I'm looking to adjust the boost in car. Is the Greddy Profec Type 2 the way to go? Thanks John

What, if any, piggy-back or standalone ECU parts do you have now?
The ISAC system that was released a few years back looked really cool... especially as a boost and alky controller.
-
Are you looking to just increase the boost? Or are you looking to set the ramp or pull boost for launches?
-
Im running the stock computer / TT chip.. Just looking to increase / decrease boost inside.. Currently I have the RJC controller. John

Just put a turbonetics boost controller in it.

remember that when you increase the boost, the car will run lean unless you reprogram the chip to match...and if you reduce the boost, the car will be too rich unless you...

Steve, i have the TT chip for my setup with Alky.. currently running 20lbs.. prob going to 23-25 once i figure out my false knock issue.. Would i need a new chip burned even though i have an Alky one?

That style was the first in car controller I used. Not Turbonetics brand but was pretty accurate with 1 full turn being 1lb of boost except after about 5lbs it wasn't that accurate. My BSTC is being donated to Santa Dave for his experimental use.
This thing here is probably ok for 90% of us. Mount it close to turbo & run a toggle switch inside the car. Altho I'll probably just leave mine tuner style since the track days are so rare for me lately.

I got a ball & spring style from one of them for $25 that has worked well for the guy I gave it to try out. The ceramic ball added the $5 otherwise $20 shipped.

AMS is probably overkill.
I suppose the question is how you want to control the boost? As mentioned earlier you can play with ramp in/out rates or just total pressure.

If you have an aky chip...what did you tell Eric your max boost was gonna be when you ordered it? If you told him something like 25...then you should be able to turn the boost up to that level on the default setting. Low gear and 3rd gear fuel is adjustable.

As Brad said, fuel/air will be close at whatever boost you gave Eric when you ordered the chip. Eric has a pretty wide range of adjustment on the fuel so it should be okay for the range you are aiming for if you did not give him 25 initially.
Brad also makes a good point. Many of the chips seem to be on the rich side-particularly in first and second. This can really kill the spool up on the turbo. I have seen some real traction problems caused when the chip was dialed down on the fuel side :)
Personally, I think, on street cars, that there is no need for an in the cockpit control and they can cause more problems than any convenience they might offer. I would spend my money on something more rewarding :) Set the boost and leave it alone. You don't have to go full throttle all the time...

Some mornings I wake up and I want to watch amateur porn instead of paid performers.
Some days I like eating cow and other days I like eating fish.
Every now and then I wear jeans and sometimes I wear slacks.
But, I never want to run 17 pounds one day and 21 on another and 19 on another.....
For all the posts I've seen over the years on in-car boost controllers, I've never seen an actual real life reason to run one.
What am I missing?
When I want to lower my boost I just don't floor it. :\
-
The chip was burned for 23-25lbs...(per Eric). I currently have the RJC controller and I plan to stay around 23lbs..Thanks for the help. John

On a pure street car I agree. I run 17 psi on pump but would like to turn it up when at the track. My buddy runs 10 flats in his little 4 banger with 33psi of boost but on the street only 22 and of course he never cranks it from 22 to 33.
Maybe you're missing a good HD tv for your porn? :icon_lol:
-
Thats what i want to do.. Run 18-20lbs on street (93 and Meth) .. Then when i go to track, run a little 100 unleaded and dial boost up. Thought an in car controller would be easiest...
-
Why not run 17 on the street with straight 93? It's a bit hard to dial down the alky and keep from being overly rich at 18-20 in my experience.
No need for any mixing with 100 if spraying meth.
oops, I forgot about the three people that always post they run 20 on straight 93 :D
-

It is. It just comes with a cost. I am the LAST person who should tell anyone not to buy that cool-guy part because you want it. If it makes you happy: do it!
I really like the MAF Tuner Pro boost control function. I can set it to ramp in as I desire and can have two boost settings for high/low gears. However, I have had little need to adjust it after I got it set properly... but, setting it up was made pretty easy from the driver's seat.

I can run 20 on straight 94 with the stock turbo on my low milage car and ran 22 with the TE-44. But I can't get that high with the CPT-66. :( I think I need a really big pump! :icon_lol:
-
No...the 66 just flows a lot cooler air at the level so the charge is much more dense. It ain't the boost, it is how many air molecules it can squeeze into the cylinder which is a function of density :)
-
I've got the IQ of a house plant...so I have no choice but to adjust the boost on my car with the actuator rod.

Speaking of dense, where has Zap been?
Absolutely, Steve! The 4.1 car ran an 11.8@116 smoking the tires off the line and losing cylinder 5 right after the 1/8 mile on straight pump gas without the converter locked, with 18' of timing. Should be low 11's capable on pump gas.

Tim seems to disappeared for good this time. He made one post on FB awhile back but he has not answered any emails or told me I was an idiot in a long time.

Well I hope HE's writing a sequel. Maybe Supersix can call him again?

Steve,
You are correct about running rich at 20 lbs with Meth. I am running very rich at 20lbs with meth currently..(tuning now)..think im going to bump the boost to 23 this weekend....hop efully that will lean me out a tad. Also, bought the power logger to help. John
-
so, when you get to 23, you don't need a boost controller any more because who changes the boost a couple of pounds and retunes the car? I would set it at 24-25 which will probably be close to what the chip is expecting and Fugettaboutit :D
-
Your right ! whats 1-2 lbs :)

Years ago Dan was out with some broad in his GN. He had the boost controller in the console. He could dial it up or down for whatever boost pressure he wanted. He gets out of the car to get coffees...and unknown to him she starts playing around with the boost controller in the console. Later on in the evening he gets into a stop lite race. You guessed it...the boost was wide open...and out come the head gaslets.

One of the State Troopers and his brother were over the other day and wanted to sight in a rifle. Seems the brother's wife picked up the gun and asked what the knobs on the scope were for as she was twisting them....

Head Gaslets - an accurate description indeed
