    Default What OS for using Stoich...

    I have 02020003 V3 and all the tables are numbers instead of stoich, real irritating! Is there a version or a way to convert what I'm using so its easier to program?

    Also, in speed density mode can all the fuel calculations be off just ONE table instead of 50 tables all modifying each other!?

    The way I see it, I need a base map, cold enrichment map and an accelerator(TPS) map. This is a drag racing only application and there just does not need to be so many modifying tables!!!

    In tunetool: Edit->Properties->Commanded Fuel Values->Display In set to AFR.

    I don't understand your second question... The PCM has an algorithm which looks up the a whole bunch of various tables to determine airmass, fuelmass and injector pulse width... this is just how it works. If you do an AutoVE tune, then after having done that, there will be only 2 tables at the very most that you have to tweak to control the AFR.

    Thanks Joecar - As for the second part, I figured all that out for now....

    Since I've had a lot of seat time with the Holley Commander 950 it just helps confuse me with GM's way of doing things.

    Remember, GM's PCM's are for driveability quality on production cars and have many more features than the Commander.
