hey all, just want to say thanks in advance for any help provided.
old setup was afc/keydiver/2g maf
now i have afc/vpc/keydiver chip.
the vpc came with a 660 chip. the keydiver chip is set for 550's (i had denso 550's before).but since i put the vpc in the i had to subtract a lot from the afc just to get the fuel trims back on track. for idle i have it at -35% (before was at -15%) and even with that the fuel trims are in the low 80's which is still very rich IMO.
*should i have jeff reflash my chip for 660's?
*should i put back the 550's and use the stock VPC chip? i think this would probably be the best option for now just to see what happens.
*anyone else with the same setup that could tell me their rough settings for the VPC?
my setup:
B16g running 20psi, denso 660's, rewired 255hp walbro, Aeromotive fpr set at 37psi, FMIC, external tial 40mm, 2.5" exhaust.
