Putting A Chip In A TBI Truck

[woody80z28]

I was going to go 7427 for my Camaro injection retrofit until I found a steal on an aftermarket Accel DFI setup. And if I don't like the Accel I can always go to the tried and true GM. TunerPro RT and an AutoProm make it pretty easy to tweak.

how does one get started with all this custom chip stuff? i want to be able to dial in my truck a little more if possible and maybe start some side work for all my gmt400/fbody friends.

You may have an idle fuel table that is out of sync with the main fuel table. I know that with my truck (7427 ECM), any time I change the main fuel table, I have to make sure the idle table is in sync with it our else the truck will hunt at idle.

i havent gotten anywhere close to fixing it and ive tried alot. i cant drive it far to take it to my firends that can mess with the fuel tables either.
