Someone correct me if I am wrong on this

VE = base fuel map
AE = Part throttle acceleration MAP/Modifiers
PE = WOT fuel MAP/Modifiers

Datalog looks very rich and your IAC counts looks weird starts high in the beginning and at the end it settles down to zero??? If you can get it to idle decently, consider doing this: http://www.gearhead-efi.com/Fuel-Inj...-Fuel-Pressure

The issue with the IAC is what I am trying to fix, not sure what is going on with it. I changed the VE1 corrected table and got it to idle and start better but now it dies when i put it in gear.

Kacy, by any chance have you checked the IAC wiring. I have seen a couple of instances where the IAC wiring was installed incorrectly, especially when changing IAC styles like going to a big block IAC

I haven't had a chance to try the idle set procedure as I just got back and its sub freezing here again. When it warms up a bit I will try the reset procedure.

@davew do you remember if that tune was to work with stock pump and psi or TPI pump and 18 psi?

Ok thanks Dave.

I have correct the IAC issue it now reads between 15-18 steps while idling warm, but ti still idles at 1k rpm will not go lower unless in gear. I sprayed the base of tbi and adapter and no change in rpm to indicate vacuum leak.
