New chip
« on: July 31 2020, 02:09:17 AM »
time for a different chip. I have a TT 6.1 and have a MAF translator 
Thinking of a Bailey Extender or TT 5.7.

They are both good.
I prefer the extender slightly tho because the computer controls the fuel at double or triple the 256 grams per second of a stock or TT chip which is an educated guess above 256.


Or get both and see which 1 you like.
I think TT sells both.

Read the instructions to both and see which makes most sense to you.

You have the 6.1 (WBo2) why go back to the 5.7 or extender?

I'd be looking at the sd2 chip :)

Just turn off the WB tracking and you'll have a 5.7.

and save $125 on the downgrade.

The 6.1 is my recommended chip.  After helping William A. tune his car for several years and various chips, I really developed an affection for the 6.1.  One has to be really dumb to mess the tune up.  The most important thing is to have a wb that reads right.  I came to realize that tuning is not very sensitive on a ten second car and there is little need to stray far from Eric's defaults.

Your all correct to put the 6.1 back in a box has to be the dumbest thing to do. It works so good. Set it and forget it. I’m obsess with my poor 60 foot time.  I try to get enough fuel pulled out to get the car to 60 it wants to knock in the top of 2ed just before the 2-3 shift and no improvement in 60. Turning WB off only gives control of fuel and spark in 1 and 2 together
Looks like the 5.7 will give me low gear fuel and timing  2-3-4 in the other window .I’m definitely to dumb to go SD.
Got more reading to do tonight.
Thanks for being a good place to express my dumb thoughts. And I do here your good wisdom

Tim...turn off the alky and go with race gas at the track. You can throw a crapload of low gear timing at it and you won't get any KR. With loads of low gear timing it'll launch like no ones business.

After reading Russ/Melissa's write up, I am going to disagree.  :D

Leave the alky spray on and bump the timing.  That and a converter that gives you enuf rpm to build boost on the line will throw you thru the sixty foot line.

I would be sure to measure the instant center of the car to be sure it is not out ahead of the front bumper.  Then it's up to you LOL

I would agree with you Steve in general but from a previous post

Hard top all new bushings,even the GNX over the top with a GNX seat brace

I can hold 3200 easy been 3700 a time or to I’ll check my log book tonight
3100 @#15 is solid not trying to push through.

Unfortunately, it's a bit difficult to debate when we are short of data.  I guess ultimately we need driveshaft rpm (which very few of us have) to compare against engine rpm to determine what the rear tires might be doing.  For poor people like me, a paint stripe on the tires and someone filming on both sides might be useful...or it may just provide confusion.  I think I computed some of his rpms vs mph altho that might have been some other car.  Some converters stall up well but slip too much internally after the hammer is dropped.

With regard to alky, guys seem to launch pretty well on E85 so I wonder if it is the alky or our tune that keeps us from launching hard when spraying alky.  Perhaps we should be pulling a lot more gas out initially rather than alky?

Then we have to consider track and tire conditions plus the weather.  It is not a simple mix and we don't have much in the way of data to compare it against.  If we had two more buicks running better 60' times, we might be more easily educated.  Or, in my case, probably not LOL

Just to be clear that quote was from Tim in Sept.
should be easy 1.4 sixty's.
The only difference between an alky launch or not was a little harder to get the rpm/boost up at the line on default.
Tim does say he doesn't like to sit at the line and build boost.

PL files I'm seeing you'll have to flash the convertor to 3950 to pull a low 1.5 launch. Bring up the gauge panel and use the arrows to bump the frames up one at a time. The MPH and RPM gauge are side by side. When you see the MPH go to 1...back it up 1 frame to zero. That's the RPM it's flashing too. Pulling low gear fuel and throwing the low gear timing at it has a dramatic effect on how the convertor acts upon launch.


Erics race chip on the default low gear timing and low gear fueling with the 16930 I had in my car...you could get out and run faster. Bump the low gear timing up 6-8 degrees and lower the low gear fueling to 770-780...and the convertor was a different animal altogether. Try as you might, you'll be hard pressed to find a better convertor than a 16930 for launch and 1/8th mile coupling when the low gear tune is dialed in.


Steve can describe in detail the physics and everything else involved in adding low gear timing and leaning low gear fueling in regard to launching. Steve, it'd be a great add on for your site.
