with the afc nothing, without it any time the throttle plate is closed it maxes long term fuels trims neg trying to lean it out. almost instantly it pegs -22.7 and if I’m doing a lot of city driving it will throw a code for “fuel system too rich.”
then, any closed loop wot position it’s too damn lean. anything above 6000 Hz on the mass air flow frequency and it will knock like mad and pull timing. with the afc scaled up it’s not too bad but without I see like 8° of timing pulled from detonation, it’s too lean.
it’s god damn messed up really, I’m so damned pissed at the company I bought it off of and they won’t do anything. I woulda got a tuner a long time ago but I don’t have a laptop.
what you mean AFC?
i can wipe your ECU clean and put a fresh stock tune in then go from there to as in where you need work done…this will probably get pricey since its time consuming
