I am currently running a chromed chipped ecu and wonder if installing a vafc would be harmful? I've searched but have yet to fine a definitive answer.

I know all the hate that the afc hacks have had. If the vacf is hooked up, all I'll be using it for is minor fuel adjustments and simple data log. I am running dsm 450s and if my fuel adjustments are set to 0 across the board, will I still suffer from timing advance from the vafc? Also, with the vafc adjusting the map sensor signal, will this hinder what my chipped ecu is program to do? Any helpful information would be much appreciated.

 

if you try to fine tune with the vafc while running a chipped ecu you will chopping farting crap running car. say you have your ecu retarding the timming 1 degree for every pound of boost. but you have the vafc turned to -20 some where in the rpm band you ecu will not get the signal to retard the timing becouse the afc minimized the signal.

i was just like you at one point in time but then i "converted" your best bet is to just sit down with crome and not move till you get it figured out that is what i had to do took about three days.
