Okay, I just got my diagnostic scan tool and my laptop.

I am trying to figure out what the:

Block learn cell number,
Block learn muptiplier,
Integrator,
Injector pulse width

are suppose to be. generally speaking of course.

Trying to figure out if the prom chip is burned correctly or if I need to invest in doing another one.

Any help would be much appretiated.

I'll take a stab at this. BLM and INT is optimum at 128. Anything over and the ecm is adding fuel and vice versa on either BLM or INT. BLM cell will vary by what load (or g/s), rpm you're in. Really doesn't matter much in the real world what cell if BLM is always 128. Oh yeah, at WOT ecm goes into open loop so no BLM correction, it's at 128. Inj PW can vary a bunch. At idle more than 2 and less than 5ms is acceptable but by no means a rule. At WOT (depending on RPM?), 20ms I believe is lock up. General answers to a general questions. I don't know if this thread belongs here though. You never mentioned it but it sounds like you have a GM ecm and the answers I gave were for one. It also sounded to me like it has a bought prom and not owner tuned. This board is more for aftermarket ecms. If you decide to take it to the DIY prom board don't bother asking if it would be worth burning your own prom as the answer will always be, "YES". Either way, GM or aftermarket, you have the best mean of tuning your own car. No one is going to want it as perfect as you, even if they're getting paid for it.
