6.1 is simpler/easier and will get you close enough. Eric even suggested I work w the 5.7 chip longer. I have the car running good on it too. I like he doesnt just try selling you the most expensive setup either. I however pulled the trigger on a SD2 cause I want to learn how to tune/read VE and spark tables.
Tunning with an SD or a 6.1 (Chip).

Best ET w 5.7 TTchip was 11.3@122mph and 1.9 60'. Keep in mind that was only my 5th pass in my life. Kept shaving .2 sec off ea pass just learning how long to burn out, what boost to launch with and etc. That also wasn't w a built rear end, transbrake or 2step. Next yr I'll utilize all of that w my SD2 and see what I get...track experience plays a huge role though also
Agreed. !! I don't even race anymore but still run the SD2 and love the extra tuning ability. My wot map was close and didn't need but a little tweak. What I play with is the cruise map so correction is nill. With a little practice it's actually fun

It may not make sense to some folks, However I don't know anyone who knows more about these cars then Richard Clark. With that said going with his advice .

either one. they both work well.
Since you went with SD2, go ahead and download tunerproRT software and locate the .xdf definition file for SD2. It's much easier and much more convenient using tunerproRT to edit the SD2 BIN files than it is to use the powerlogger. The definition file for SD2 is located on the turbotweak support board and it's also posted around here in a few places too.
I think if you log into the racetronix support board you will find the fuel injector offset data that you need to get your injector offset calibration setup to precisely match your injectors. that's where you want to get started. Having the injector offset right in the beginning is very helpful later on. Most common turbo buick injectors are characterized on that support board.

If you go SD2 you will
Never need another chip again . If you have the supporting equipment to run the sd2 I would definitely go that route . Any future changes u do you can go and change the settings with sd2 . Plus you get to ditch the MAF which in it self is a giant plus . I'm running E85 with the SD2 chip and have it set up to change the tune per ethanol content. Just my 2 cents . Good luck whichever way go

I use TunerPro RT v5. It's still a freebie like regular tunerpro.

I have the 6.1 and am pushing it way past what it was burned for. Looking forward to moving to SD2 to gain some flexibility in my tune. I wish I had bought SD2 to start with although I cant fault the 6.1. Its been easy, reliable and surprisingly good at correcting for bad baselines etc. Someday I hope to see fuel pressure correction / compensation added to Erics chips like xfi. I eventually see myself going xfi it just isnt in the budget right now

Can't speak for Richard Clark's knowledge of tuning chips but I would agree he know's a lot about the car itself. I think the people that shy away from this type of technology are the people who don't understand it so simple is better. You can argue both way's I guess.
How do i find injector offset data to calibrate my injectors?
This Steve, Prasads buddy? How else can I go about getting the fuel injector offset data to calibrate

I cant see anything on the racetronix forum, they allow me to sign in but nothing is viewable... Must be cause they know I own a turbo buick. He made it clear that he didnt want to support those w turbobuicks anymore due to some past history...idk, its what he told me over the phone earlier this yr.
Steve at FTS just said the fuel injector offset data will be all done by Eric @ TT for the SD2. Shouldn't have to worry about setting that up then when I get started.

It will be in the ball park. I never use published injector offset data. I generate my own on the car under actual running conditions with the Buick ECM.
So there is no standard injector offset data to a particular injector. Wether the data is from you or from Racetronix, its just data put together from past experience that will get you close. Since every car is different tuning that data will be required.

Dave how did you get CF% to show up on the graph page.INI file ?
