The TBI: 1989 1228747 GM computer, Big Block Throttle Body, bored out as big as it can get, Big Block #5235231 fuel injectors, and around 28 psi fuel pressure at the moment, 355 ci 11.8 to 1 cr. BPW is what now?

Look at this calculator and you can determine BPW (Base Pulse Width) it is the starting point of all fueling.

The $4F BLM history table was off so I fixed it.

Also added the ESC test paremeters. Looks like 3200 RPM is limit so the test happens under that, maybe lower to 800 so it never happens, also the test1 and 2 spark advance are there, set them to 0 and also knock count to pass test to 0... all theory untill proven!

Ok, so I set all as you stated above, man, you are the MAN! thank you so much! I'm at work so I'll have to re-burn my chip when i get home tonight. I'll let you know how that goes. Again, thank you so so much!

Oh one other question, how do you define the COMM PORT for TunerProRT? I can use the same dongle as I did for winALDL, or do i have to get something else to make that work? I tried hooking this up over lunch to get some logs recorded but she didn't recognize the ECM when I plugged the laptop in. (sorry very new to all this)

Since we go through this all the time I made a sticky!

Ok so did as you suggested: "lower to 800 so it never happens, also the test1 and 2 spark advance are there, set them to 0 and also knock count to pass test to 0... " when I got home, burned the chip, plugged it in, and had to go out, so I didn't get a chance to do a set of logs with TunerPro RT yet (did get it to work, thanks for the sticky!!!). However I can say as I drove the caddy, that seemed (just from seat of the pants feel) to smooth it out some. I'll know more tomorrow and keep y'all posted. THANKS SO MUCH FOR ALL THE HELP!!!
