Hello, working on a 1988 GTA

[eseibel67]

I recently changed the cam in a 1988 GTA LB9 5 speed. It runs great, but it stinks at idle, and I think a tune might fix the problem.

Not sure what equipment I need, but I find all the computer lingo very confusing. I have a couple of spare stock PROMS for burning, I'm ok with popping them in and out as changes are made.

Looking forward to reading though this site. Any advice would be appreciated.

HAHAHA! I just noticed my status is carb & points! Yes, tuning to me means jets, metering rods, weights and springs.

Very funny.

You'll work your way up with posts to Electronic Ignition before you get to Fuel Injected...

We were all beginners at one point in time.

I think the best place to start is with an ALDL cable and laptop with TunerPro RT to learn data logging.

Thanks for response. I have a professional scanner so I'm fairly familiar with what good data looks like from the various parameters. The area I need to concenrate on is the integrater and block learn, which I assume are similar to STFT and LTFT.

INT = Short Term Fuel Trim

BLM = Long Term Fuel Trim

You can make some VE fuel adjustments based off scanner, but with TunerPRo data, history tables and a spreadsheet you do way better. You'll need TunerPro anyway to make changes to chip/bin file and it also does Data Logging.

Seems like you have car skills, now you need to work on PC software skills!
