Title: Turbo Tweak GN ECU
Post by: good2win22 on July 10 2018, 09:56:51 PM
Got an email yesterday with shipping info and another email today with software installation instructions. Going to be a huge learning curve for me and I would like to share the ups and downs.  I'm pretty sure there is knowledge to be tapped here from others who have used the software. As of now I only have instructions and a schedule that will only allow for reading till the weekend

How PnP is it? What do you have to do electrically to install it?

I assume it does away with PL, Scanmaster and such.  Does it have any alarms built into it so you have some warning when the laptop is not connected?

It's an ECM replacement with whole lot of stuff you can play with and mess up.   


How exactly PnP is PnP here?
Remove stock ECM.  Plug in harness to GN ECU. install wideband in downpipe.  Run wire to wideband from ECU.  Run vacuum line from manifold to ECU.  Start engine

Bob is working on a "dash" and I assume there's already something out there for the MS3 that can be used.  Haven't researched that.  No need for cables, built in stand alone wifi. But if you must use a cable, there is that option as well. I have heard that folks with this tuning software sit in the stands and watch the run on the laptop live. Not sure I'm willing to test that. Most folks using the Mega squirt systems have gone away from tuning to KR.  They don't feel that the time it takes to calibrate the sensor is worth the effort... I don't get that. Something about frequency changes after going so far away from a stock configuration.  Eric has three dashes to choose from on the software.  What's in the video I posted the link to, a GNX style dash and a dash that has like everything you could of think of.  I kind of played with it a bit this afternoon.  I put up the gas afr gauge next to a gas lambda gauge, made the correlation visual.


Going to play with it tomorrow while on shift and see if I can set up a fuel pressure table, calibrate it and then put it on a dash somewhere.  Have to work on Friday a little bit as well but should be back at the barn Friday evening and all weekend to get more familiar with it and clean up the install
Title: Re: Turbo Tweak GN ECU
Post by: Steve Wood on July 12 2018, 08:18:07 AM
If there is no prevision for KR, then I would guess there will be a bunch of people that try to run 30 psi of boost on a 25 psi engine.  Back in the days when I could still claim I could hear, the only time I heard detonation on a TR was immediately followed by a blown engine.

The frequency of detonation in a stock block is reportedly around 6k hertz.  If the factory could monitor it and pull timing, I would think it could be done today as most high performance engines pull timing as soon as they hear knock.

I would also like to track fuel pressure and shut it down when it dropped something like 10% from the boost level.  How many times have I seen people basically running on alky because they did not realize their fuel pump was dying...severa l times.

The easy install and immediate start up is very impressive.  They will sell a bunch of these things. :)

As far as dash, will a tablet work? Something to slip in front of the giant speedometer.

Next thing comes to mind is the wifi. Is there a way to "lock it down". The statement of "sitting in the stands" worries me about the element of people who might be up to no good . Strong password?

Incorrect. The CEL can be used as a visible indicator of knock.  The pulling of timing when knock happens is all tunable

They took a well proven platform and tailored it for the Buicks so they did not re-invent the wheel but they customized it specifically for our cars and added enuf features to make it run out of the box without having to import a trained monkey to tune it after each race.

The best thing is that it was brought to market by two really nice guys that have always bent backwards to help people.

Steve - until people stop tuning off knock threshold they are still going to break stuff.
Title: Re: Turbo Tweak GN ECU
Post by: Steve Wood on July 13 2018, 11:48:43 AM
All I know, is that if one is running 25+ psi of boost and the fuel hiccups, one has a very expensive mess left under the hood.

I don't know exactly what you mean by knock threshhold as I have always run a couple of percent more fuel at a minimum than what testing showed I could run without detonation as I have found it makes minimal difference in performance to be a little rich.

I also know that fuel quality varies as do ambient conditions and I like to stay away from all the possible lines that I can think of.  Having a management system that tries to save the engine seems like commonsense to me if something goes wrong.

Having the ability to monitor fuel pressure and alert me early is better than finding out that the pump is going away too late.

I distinguish between warnings and tuning.

Post by: nocooler on July 13 2018, 12:40:23 PM
Steve - I’m talking about the guys that keep turning it up until it knocks, and dialing it back some. Where they could have snuck up on it and found that it’s perfectly happy with less timing than they are trying to feed it.

This ecu can do all of what you want and then some.

Door 1. You can change your fuel pump once a year. It's about a 2 beer job and hundred bucks for a new fuel pump. Door 2. Or, you can go WFO with a pump going weak...and learn how to pull your engine and swap head gaskets and spend a crapload of money. Door 3. You can also leave the engine in, and lean over the fenders to change them and blow your back out.

Define raced. You've been at this a long time. How many sets of head gaskets have you seen lost going WOT, whether it be on the street or track due to neglecting fuel pressure and the resulting detonation. 
Title: Re: Turbo Tweak GN ECU
Post by: Steve Wood on July 13 2018, 07:50:57 PM
have no idea.  For raced, I meant cars regularly taken to the track and running boost above 17 psi.  I admit, I have seen quite a few cars spraying alky survive blown hgs because the alky covered up the lack of fuel.  That is why I initially asked about logging fuel pressure and settting off an alarm when the pressure dropped some percentage below the boosted expected level

I've have my eyes open for years for a differential switch that can handle fuel for that very reason.    I haven't even came across one I could modify.

You've got a great idea of an alarm or light going off or both, if the fuel pressure drops to a certain point or percentage. Now, I'll ask you another question. How many people have admitted to you and how many posts have you seen, where guys have kept they're foot in it even tho the knock gauge is lighting up like a xmas tree.

Remove stock ECM.  Plug in harness to GN ECU. install wideband in downpipe.  Run wire to wideband from ECU.  Run vacuum line from manifold to ECU.  Start engine
That is pretty PnP - did it come with a start-up tune from the seller?  That is one of MS biggest issues is novices building tunes - especially VE tables.
As for KR, I'd imagine you could still keep the factory ECM connected and listening to at least display knock events.  It is a weird little system converting a crystal resonance frequency to a digital signal to a timing retard rate.

This system has the ability to increase injector duty cycle to compensate for fuel pressure that is not rising one for one. Just have to tell it what the base pressure is set at with the vacuum line off

Eric emailed a few weeks back asking if anything had changed on my combo since I last purchased the sd2 from him. I replied with the only change was going to a non lock up converter. He sends a thumb drive with his tune for your combo.  Start up video is from Eric's tune. I haven't changed anything yet. I am really impressed with his tables he built. I'm going to really nail down the idle first. I'm really liking being able to smooth the tables on the 3D graph. Can't do that with fast

There - that's the difference which justifies the added expense.  The support offered is the game changer here, assuming Eric can keep up with the demand.  Demand being the issue for some highly entitled novices who feel PnP includes Eric flying to their homes to set it up/troubleshoot/tune it for the money they spent.  We saw this on a lesser scale with MAFT Pro - cutting edge tech, price, and complexity at the time - I think Bob let it die because the learning curve was too steep for the Cool Guys who got overwhelmed/disappointed.

I have no doubt you got a grip on this, so buyer's remorse is unlikely in this instance.  $3K for an PnP OS/hardware, datalogging, and direct tech support is a very fair deal.

You know the old ISAC (alky boost controller could do that).  I discussed with bob at length about a knock sensor boost cut and some other things.   In the end the lean out using the wideband is the most reliable boost cutoff.  I don't remember the details but that was the consensus.  Of course the ISAC couldn't see the fuel pressure.

Post by: good2win22 on July 16 2018, 11:43:17 PM
Got some time today to clean up the install and take a little drive. Also spent some time on the phone with Eric about using the EGR wire for the fuel pressure signal. Had to design a gauge, calibrate the signal and wah-lah, logging fuel pressure.


He and Bob truly designed this thing with a lot of thought. Although the ECU has a 4 bar MAP used for its calculations, your existing MAP you wired up to work your alky controller still works. No mods.


Oh yeah, scanmaster 2.2 still works and you can go old school and connect to the ALDL wire. Have to do a little mod and you can use a scanmaster G connected to the ALDL.


Used the auto tune feature while cruising at 55. Auto updates the VE table. 


Not one tip in stumble....

Post by: Steve Wood on July 17 2018, 08:26:22 AM
I always found it strange that FAST advertises auto tune in their ads, as do other companies, yet it does not seem to be available on the ones sold to Buick owners.

If Eric/Bob can sell you chips that you can plug in and run extremely well with, without changing a single parameter, then you should be able to load the exact same information into an ecu and have it run well from the get go.

If Holley can sell you a system that you dial in your specifics before you crank the car and then drive off while it self-learns, then surely, FAST could do the same thing...EXCEPT, tuners would have a greatly reduced business.  And, once the mystique has been removed from the process, tuners will have no one to blame, except themselves, when they cause an engine to blow by tweaking it too far on the dyno and it will not be able to hold up under real world conditions.  Very few of these guys ever admit to being at fault.

If the Buick crowd figured out the auto tune it would seriously cut into the business model of those "tuners". They aren't doing that.
Sounds like this one will be the go to in no time. Everyone will have the base tune and be all over the "cool guy" I have an aftermarket computer .

Jason is way ahead now. Mid tens on the horizon and some high nines in the back of his mind.

As someone who sells the Turbotweak ECM (and Ihadav8 members can contact me for special..."promotions" for the cost on this ECU)

I am really excited to see how spot-on Eric's tunes are, and how easy it seems for people to learn.

For those who have recently purchased this ECU, how did you go about learning the Tunerstudio program? I have a local customer who is thinking of getting one of these, but I have never used Tunerstudio (other than play around with the program on my laptop, not hooked up to any ECU or vehicle) and I am looking for somewhere/someone who can teach me, or just show me WHERE to go in order to learn the Ins and Outs of the program.

I have the drive, the desire, and the motivation to learn Tunerstudio. My problem is that I have looked far and wide and have not found anything that can teach me how to use this program, and therefore I am stuck in this purgatory of inability to learn Tunerstudio!

Any help..ANY help..would be INCREDIBLY appreciated!!

Tunerstudio is pretty nice. Download the software, and they have some sample projects you can look at. If you’ve used any other tuning software you’ll be able to find your way around.

Jason, is it doing boost control with the stock solenoid? Planning on using it to control your alky?

I haven't messed with boost control yet. Still doing it with the RJC manual boost controller. I have plans to use the ECU for the alky control but haven't got that far yet

I always found it strange that FAST advertises auto tune in their ads, as do other companies, yet it does not seem to be available on the ones sold to Buick owners.

If Eric/Bob can sell you chips that you can plug in and run extremely well with, without changing a single parameter, then you should be able to load the exact same information into an ecu and have it run well from the get go.

If Holley can sell you a system that you dial in your specifics before you crank the car and then drive off while it self-learns, then surely, FAST could do the same thing...EXCEPT, tuners would have a greatly reduced business.  And, once the mystique has been removed from the process, tuners will have no one to blame, except themselves, when they cause an engine to blow by tweaking it too far on the dyno and it will not be able to hold up under real world conditions.  Very few of these guys ever admit to being at fault.
I've been preaching open-source tuning for years - it is good to educate the masses.  And yes, pro tunas are never responsible; leaving 5-15% on the table is fine at today's power-levels.  Some of the shitty LS tuners out there should be drawn and quartered for the deception, misrepresentat ion, and theft they do.

Lock up the pcm and get something busted in their end. Sounds like blackmail to me. I can't imagine that shop would last very long. But people are pretty stupid and I guess have lots of money to throw around.

I guess it is a good thing I don't care to have anything new. Seems like making things hard to repair hurts resale value of any new one. Kinda counter productive to get a "right now" score. But then that is how the new wave of business works, this quarter profits, we can worry about next quarter then, and next year or decade isn't even thought about. No wonder stuff doesn't last very long.

If I was farming I sure wouldn't buy something I couldn't work on. Tech marches forward. I'm sure someone will crack the code. If they can dream it up someone else can hack it. https://www.breitbart.com/tech/2016/12/30/report-self-driving-cars-can-hacked-just-43/ (https://www.breitbart.com/tech/2016/12/30/report-self-driving-cars-can-hacked-just-43/)

Farmers are buying illegal copies of repair manuals and interface software from overseas - the problem is getting parts from the OEM.  It isn't like RockAuto carries Dorman parts for a John Deere tractor.

And then there is how long those parts are available for before the whole thing is rendered obsolete.
Title: Re: Turbo Tweak GN ECU
Post by: TexasT on July 19 2018, 11:36:03 AM
Lots of stuff will come to market if the OEM doesn't support its wares. China, India, Hong Kong, Korea have manufacturing ability way beyond what we think I am sure. Pretty much everything Is produced over there now. Even the raw materials are over there. And sent there from here by the container/ship load. We as a country have taken our economy to selling money instead of actually producing anything substantial. And with the over saturation of lawyers/attorneys taking us back to the times of the robber barons of yestercentury the little guy gets short end of the stick.

To get back on track, how is the fooling with the software going on the Jason end? I would be interested to know what Mr bison has to say about the setup. And anyone else  who has fooled with it.

I'm glad to help in any way that I can!


Here is the link to the controller. I believe they are retail of $499, but the "ihadav8 discount" will put that..well.... let's just say you'll be a happy camper :)  Link: https://www.diyautotune.com/product/microsquirt-can-transmission-controller-4l80e-subharness/ (https://www.diyautotune.com/product/microsquirt-can-transmission-controller-4l80e-subharness/)


I was actually talking to Brad the other day about providing everyone in Canada with special "across the border" pricing. I know they get hit hard with the exchange rate and customs, so I was going to change my entire pricing structure for people over the border so that they can hopefully afford badass parts without getting completely screwed from the exchange rate and fees.


I figure who cares if I don't make all the money possible on something- that is the WRONG reason to become a vendor. I'd rather just make enough to cover my buy-in costs/etc, and sell it to the guys up North for basically what I pay for the stuff, maybe mark it up 5-10%, depending on the product, but this way they can hopefully save hundreds of dollars on parts so that even with the exchange rate being what it is, they are still saving a lot of money.


I don't think it is fair that the guys up North are not privy to the same parts that we are, simply because the country they live in charges incredible taxes and tariffs on the parts, and the exchange rate is awful. That isn't their fault, and their car shouldn't have to suffer for it. If I can give them turbos for a few hundred dollars off, or ECUs for hundreds less, then I will, damnit! No reason their car's performance should suffer just because of their location....


Anyway, sorry for the rant... if you're looking to get that 4L80E controller, or anything from DIYauto/AMPefi (they are the same company) please let me know and I'll hook you up on the cost.


Actually there are probably very few things you would need for your car that I wouldn't be able to hook you up on! hahah! You'd probably be surprised at all the companies I am a vendor for....

Dude anyone can go to the classes! ....or at least I HOPE SO! I sent in my application to attend on Friday, and I'm waiting for confirmation of my seats. Hopefully I receive an email back on Monday confirming my classes.

The courses are November 3rd-7th, and cover Tier 1 on the 3rd, Tier 2 on the 4th n 5th, and Tier 3 on the 6th and 7th.

Tier 1 course is $150. Tier 2 and 3 are $225/ea. I know it will be a lot to absorb in a short period of time, and with hotels/car rentals/airfare I'll be spending a good $2,000-$2,500 but I firmly believe it will be worth it.

Not only to educate myself on the Holley Dominator I plan on running (shhh! ;) )  but to help kickstart my career as a tuner by learning as much possible and being certified in a specific ECM/software. From there, the goal is to eventually apply my knowledge of the Holley software to the TunerStudio and XFI softwares.

Aside from all that, having certification from Holley that I actually know what I am doing (because I admittedly do NOT know speed density right now) will allow me to garner better labor rates when I tune people's cars (I'd never charge my friends...that is a given) and hopefully add some legitimacy to the status and respect of RPS in the eyes of my peers. Hopefully they will see this as a genuine step forward towards learning "real world" tuning procedures and abilities.

Regardless of what my peers say, I'm stoked to take the courses so that I can learn this software and truly maximize and tune my own setup once I get my Dominator! I am doing this for ME, SCREW what everyone else thinks!! :D

I really don't feel that the ecu will make the car any faster. The ease of installation and Eric's start up tune was definitely a bonus for knuckleheads like me.  I believe it's the software running the ecu and the ability to manipulate it is what the makes the difference. Being able to analyze the data and make the changes is what makes it fast.  With the mph I've already put down, I'm hoping for mid to low 10 second pass at the current power level.  Maybe turn it up and see where it goes from there...  I don't have a cage in the car, so that's a factor as well

Are you having issues connecting your laptop to the ECU over the supplied wifi?




When I was first looking into the MS3 units and the ShadowDash application, I found out that Android tablets (or phones) have more difficulty connecting to the ECMs using Wifi than using the Bluetooth connection.


For whatever reason, the Android tablets that were using the Shadowdash app could connect much easier and more consistently with the Bluetooth, than the wifi. The Bluetooth had barely any delay, and I mean so little that if you were using it as your dash/gauge cluster, I would have no concerns about how quickly it was able to receive and display the information.


Food for thought- if you run the ShadowDash on an Android tablet, you can use the application MSDroid for Android devices, and actually make tuning adjustments on the fly with your tablet and have it saved to your ECM! So not only could you have your own custom dash with the Shadowdash, but you wouldn't need a laptop because the MSDroid application allowed you to make tuning changes with the tablet!


Just sharing some info that I found helpful at the time.

I was introduced to a feature that the FAST guys don't have.  The spark, AFR and VE tables can be triggered to go calculate fuel, meet specific AFR and specific timing from more than one table each.  The AFr has 2 tables, the VE has 4 tables and the ignition has 4 tables.  That means that spark, AFR and VE can be set up by KPA and rpm and then triggered to go to the separate tables when above a preset KPA.  That's more tables with more resolution that can be fine tuned at set KPA and rpm.  Here's a pic of the two VE tables I have set up

Not at all.  Just some more features.  Although the GN-ECU does have a faster processor than the XFI

Boost control would seem to me the most useful thing.  Alky control might be useful for those running two nozzles when it comes to keep from spraying too much, too early

The extra tables are more for show than go imo. :)

I always start at the end of the equation and work backwards.

In drag racing, particularly 1/8 mile racing, There are two segments of the race.  Launch and finish.

During the launch segment,  we leave the line around 4000 rpm, or faster, with a good converter and shift a moment later at something like 5800 rpm. The main part of this is getting the car to spool quickly and reliably so the car is well within the power band when the hammer is dropped. From that point to the shift out of first, tuning is not particularly sensitive as the load on the engine is relatively low after the initial hit on the tires. Timing and A/F are not that crucial.  The hardest part is tuning so the launch is nailed.

With a good converter, second and third gears occupy a 500-800 rpm band on a good combo.  It's really easy to tune A/F and timing on a narrow band with the main emphasis being acknowledgemen t  that the torque converter is applying a variable rate load on the engine which means we tune largely on the bottom end of the gears where the load is and ensure top end has just enough.  1/8 mile tuning is very simple because the engine does not have much time to build excessive heat...particu larly when spraying alky.

1/4 mile racing requires a bit more emphasis on third gear because combustion chamber heat can get away from you if not anticipated.

Contrary to all the discussion about processor speed and such, it's all negated by the short time and rpm band in which we operate.  A chip will produce the same times and top speeds as an aftermarket fuel management system.  BUT, an experienced tuner can quickly adjust to wide swings in ambient weather conditions and adapt to changing track conditions that affect traction if there is a provision for boost control.  24 out of 25 don't understand the process due to being occasional racers that show up a few times a year.  Those guys may well be more consistent on a modern chip.

In the end, the faster you are, the more crucial becomes launch-especially if there is a car in the next lane that you have to beat.

No sneaky stuff on VE table 2. My converter is on the tight side. Flashes around 43-4400 on the launch. Shifts at 5800ish and rpm drops to 46-4700 on the 1-2 shift. The 2-3 shifts at 55-5600 and drops to 44-4500. I scaled ve table 2 so that I could uses this table for that specific rpm range. Way more control of fueling in the "power band"


Boost and alky control are already integrated features in the software. Just haven't got that far yet plus I don't have a boost leash or external waste gate.


I'll be home Monday from work and plan on doing some testing of my ignition issue. Going to run a hot wire from the alternator to the coils. If that has positive results, I'm going to ditch the TR6 and run the ignition thru the ECU. Bob got me a connector to mate with the CCCI connector that will be routed to the ECU via a can bus connector. Still have more more than 7 open inputs not counting the unused wires on the engine harness connected to the ECM.


More than likely I have the cart before the horse but is that out if character of me?

These tr6 coils, are they set up like the ing1a coil on/near plug? Or is it more like the stock setup with the stock coil and box to fire ccci thing?

The coil setup on the 3.1(off topic engine) doesn't seem to take much to fire it as I think it is a plate, three two "conductor" coils and a module that plugs in that I think has four conductors. Doesn't seem too complicated but I don't really know as I plug it in and It works on that car. Though it gives missfire code and a check engine light sometimes.

Pretty interesting stuff.

Yesterday I wired up the coil on plug to run the ignition system from the ECU. That's right, no more TR6. Although I'm still using the TR6 box as a mount for the coils at the moment. Quick chat with Bob, a few ignition settings changed on the software, and car started right up. Need to re-verify timing this morning since the settings changed and then make a few test passes. Big bonus is now being able to use the dwell table among other features. Hoping this remedies the ignition issue, if not, a hot wire via a relay to power the coils next.

Yes sir. Under load at peak demand, I’m getting a misfire. My TR6 didn’t get hot and the voltage strip didn’t de-bond from the board like Larry’s did but it has happened to others and it always seems to be at higher rpm’s. When you install a TR6, you get a 25 amp fuse to replace the 10 amp fuse in the CCCI circuit. Most folks don’t realize the load on the 30+ year old wiring. I have a newer Casper’s engine harness installed on my car but the coils are power hungry. Being able to control them a bit more precisely and with a bit more voltage is the plan

"I’m getting a misfire"
First, I believe you should take the following as food for thought, not gospel. My experience is apples to your oranges.

When I run into this, it is NA. Symptoms are the same as valve float. Breaks up at higher RPM, WFO. Severe cases stop accelerating. If I know the valve springs are good, I usually try to convince the owner to reduce the plug gap. Any improvement will indicate over-saturation. No improvement does not rule it out. I have not seen saturation problems with less than 7 amps supplied to the coil/s. In my world, if you do not need that MSD-7x box,do not use it even if free.What gap do you use and how much boost?

Valve float=the inability to keep the intake valve from bouncing off the seat after closing. The 206 and 212 Comp lobes common in signatures here, have been around since at least the early 1980's. I am somewhat familiar with dozens of them. They are ground on oem quality cam cores which necessitates Comp's recommendation of 90-95# of seat pressure.A 1.77" valve will have about 2.45 sq in area. At 25 pounds per sq in boost, it is about 60# trying to hold the valve off the seat. Combine that with the minimum seat pressure I require and arrive at your own conclusions. I require 110# min seat pressure from 6000-6500. 125# min from 6500-7000. Heavy valve train and hyd rollers require more pressure.What rpm are you trying to turn?

If you determine over-saturation is your problem, I would start trying to find the path to ground. Early HEI distributors at high rpm (NA) with module controlled dwell/aftermarket coils were lucky to get to 5k rpm w/o breaking up completely. I was able to cure most by replacing the rotor screws with nylon ones.

HTH, good luck.

Good info!  Springs are known to be good although they may have weakened a bit in the last year. I'm looking to go through the 1/4 mile traps between 6-6300 rpm. This cam has XFI lobes and are a bit on the aggressive side. Went through a big nut roll a while back with this cam and spring pressures.


The TR6 has a some known issues when it comes to misfiring at higher rpms and higher boost levels. Just trying to sort it out and share what comes of it. A little help from you guys never hurts either!
Title: Re: Turbo Tweak GN ECU
Post by: TexasT on November 07 2018, 03:55:28 PM
Maybe pull a spring or two and do some pressure testing.
As suggested, maybe a smaller plug gap to see if that might help.
Are there logs of the runs gettin broken up? I guess the tunerstudio will allow it to be seen if you are comfortable posting it.
I guess you got the trans under control to do the shifts where you wanted?

Keep up the good work on the wagon. It is looking GOOD!

Will this thing pull full rpm @ light load?

There is a guy who I have known for yrs, although I am not involved in any way. I have walked around his truck. He buys complete motors and the builder has great support. It is a blown methanol big inch hemi. Above 2800 hp. About 55# boost. He runs a 10 amp magneto. Plug gap is .016-.018.

One of my theories, coil over-sat is further aggravated by the inability to empty the previous charge due to high resistance. No proof.

I have a V8 air compressor. The pass side head is a 2-cycle air pump. 302 Ford. 100 cfm @ 100psi. The distributor is oem V8, with 8 trigger events for the remaining 4 cyl. If the 4 unused plug wires are not grounded the motor will be unable to take load and run smooth. It will break up before the governed 3200 rpm.

All of this to get here. If reducing plug gap does not allow some amount of higher rpm, I would look at a component issue. Probably where you are/have been already.

On a note, I would like to see you get away from increasing the voltage to your coils. Voltage does no work. The current from 12v @6 amps is exactly equal to 7amps @ 10.28 volts. Every 12v points ignition car ever produced was resisted down to 6-7 volts to the coil. My street car in 1971 went 9k rpm w/single points and single coil. Modified Production cars ran 1/4 mi w/6.50 gear and ran dual points/2 coils and reduced voltage to everything.

If you do not have @ 6 amps minimum to all coils, I would not expect another solution. If your Mean Effective Pressure is not exceptionally high, you should not need more than 6a.JMO

Yes it will go to 6000 rpm with a light load.  How do I know?  Pulled the tranny down into low gear and made what I will call an NA pull up to 6000 rpm and no hesitation. I did this to satisfy my concerns with the springs.  On a side note, talking with David Husek and he said he has seen lifters jump the lobe on cams with xfi lobes and not enough spring pressure.  Said he tore one down with a broken cam.  I can imagine there's quite a bit of force on the cam with a lifter landing on the backside of the lobe.


I could be completely wrong with today's ignition systems, but my understanding is that today's coils operate on battery system voltage and the computer controls the dwell time (we're taking milli-seconds) in between discharge cycles.  I believe the TR6 still fires the coil in a waste spark manner like the stock system, meaning the coil is firing on the compression stroke and the exhaust stroke on the same cylinder. Thus the heat build up and possible saturation.


Steve chime in and educate me
Title: Re: Turbo Tweak GN ECU
Post by: Steve Wood on November 07 2018, 10:58:56 PM
These days, you educate me!

Remember, that under boost, the springs have to do a lot more work to close the valves than they do in an NA situation.  I really don't like the XFI lobes because they are pretty violent and valve springs don't last long. Rapid acceleration worsens the situation.

I agree with your assessment how the ignition works

"Yes it will go to 6000 rpm with a light load."


Good. You may or may not be into valve float. The OEM saw fit to install 85# springs on motors with hp peak of 4400 rpm. Most will go 5800-6000. Run smooth. They are probably in valve float at 5k.


 "he has seen lifters jump the lobe on cams with xfi lobes and not enough spring pressure."

You are describing lofting. I stopped using spring pressure to control lofting years ago and I was late to the party.


 "Said he tore one down with a broken cam.  I can imagine there's quite a bit of force on the cam with a lifter landing on the backside of the lobe."

If the cam broke, it is flat tappet. I have commented on the quality of cam cores here. Probably a Comp.

"I could be completely wrong with today's ignition systems, but my understanding is that today's coils operate on battery system voltage"


I will try one more time. You will have battery voltage at the starter. The same voltage can be found at your interior courtesy light. One needs 300+amps, the other needs 0.01amps. Swapping the two power sources will not work. Just because you have battery voltage to your coils, do you have  300+ amps or 0.01 amps? You said the coils were cold to the touch. If I had issues running and the coils were cold, I would verify proper current availability. Coils do not care about voltage at the supply.


"and the computer controls the dwell time (we're taking milli-seconds) in between discharge cycles."

Computers require voltage not amperage. I have the ability and tools to measure the quality (intensity and duration) of the spark and plug resistance on running engines. Sounds like you are talking about (C)apacitive (D)ischarge ignition. CD ignitions can present serious problems.

  "a waste spark manner like the stock system,"

Forget everything I said about the inability to empty the coil charge.
