91 GTA tpi 383 Stroke need help new tuner.

Hi everyone my name is Jason and I have a 91 Pontiac Gta with a 383 Stroker that I just fired up. I have a autoprom tuner and I am using the Tuner Pro Rt software. I have everything up and running from the emulator but now I am lost. I am not sure where to start at or what to adjust it all looks foreign to me. I have already updated the checksum to AA and turned the vats off and adjusted my coolant temp but now that it is time to do actual tuning to adjust a/f and make the thing run halfway smooth I am lost. I was looking at the list of values I am not not sure what to adjust to get my block learn up it is running at 108 at the moment. I have not tried driving the car yet I was fearful of burning something up.

Jason, 108 is rich, much less likely to damage your engine than a BLM in the upper 140's. If it is not warmed up it will also run richer. It sounds like a new engine, so rich is better. We will need to know what ECM and BCC to better help you. You should also read the tuning sticky on this forum to help you understand what you are doing

Thank you for the heads up on the tuning sticky. The computer is number 1227730 and it is running bin file ANJF 4307. I pulled the stock bin file from the archives on this forum thank you for that.

There are other guys on the forum that know the 7730 better than I do, and can provide much more help.

Thank you Jim I will wait to see if anyone else responds. I understand about the block learn and the numbers but how to adjust for them in all the different sections is greek. I was trying to figure out how to even do the data logging tables while driving so that I could see what it was doing and I cant even figure that out. :confused:

I use the attached Log File Analyzer (Excel Spreadsheets) to tune $8D / '7730. Intermediate Excel skills required.

Dave thank you for these tools! I am assuming that I do a data log and input the values into the log file analyzer and than the correction log will give me the corrected values? I am new to the tuner pro program is there any good u tube videos on setting up the data logging utilities for these spread sheets? I am having a hard time even getting the data logging figured out.

first thing you gotta realize is 108 is the limit, so it could actually be 90 or 70 or 107 and you'd never know. once it hits 108, it stops.

you are trying to nail 128 if you didnt know that already.

if you want to get this done quickly, you need to baseline your fueling into a range where you get useful readings, since right now its way off.

i'd reccommend with your emulator, (have someone else drive) get it nice and warmed up and hold it at cruising range, then very very slowly raise your injector constant until it gets to..say..115-120. then you're still in fairly safe range but all your trims will probably be useable.

then do a ton of logging and fine tune the rest with those spreadsheets

steveo, when looking in my data the only two lines I see for injector are (injector pulse width low offset vs. base pulse width) and (injector pulse width low offset vs. base pulse width) would the injector constant be labeled as something else?

The log file will need to be exported as a .csv file. Attached are a few screen shot on how to export the log file to a .csv file.

Attached is a .zip sample to learn with. Open the .csv file first, then open the Log File Analyzer.xls. It will take several seconds for the entire .csv file to process.
