Hi everyone, i recently swap the pcm out of my 97 yukon with a 02 411 pcm out of a expressvan. Got it runing pretty good.
I got a aem wideband O2 and did the autoVE tune to it and thats about it.
I have msd igniton 6a, coil and wires, headers LT1 cam, full engine rebuild, no head work or intake or injector work just a new spider inside the intake.
Now that i have the AFR at its Stoichiometry. Where do i go from there. can i more Power enrichment for towing or take offs on the highway. Can i get a lean cruise out of it for long hauls to work. Havent found much on playing with the spark tables one that interested me was b5908 fuel mixture spark correction and b5919 optimal timing for torque.
Im not asking you guys to write out a whole formula but kinda a direction to a link or a write up you guys know of.
All help is much appriciated, i couldnt find anyone to tune the old prom burner in the truck so i looked into it and found out about the swap and efi live. its a lot more money the paying someone to tune it, but i love learning and this tuning stuff has always interested me.
Thanks
Ben
