OK so I just started tuning my car,
first time.
here's the setup
jdm d15b vtec, allstock except exhaust, no cat.
cx d15b8 injectors(why i have to tune).
ostrich, lc1, crome
OK so here's the deal, when i'm cruising around at partial throttle, afr is at high 14's, which is cool, but when i give it LESS gas it immediately dips down to 11-12afr then dips back up.
so say i'm cruising at around 12hg, then drop the pedal back to 20hg real quick, i'll see a huge increase in fuel, EVEN THOUGH if I cruise at 20hg steadily at that same rpm, afr will be at a normal 14somethin.
so basically when I let off the gas completely, I see my afr curve drop WAY down, then jump WAY up(as injectors cut because i'm in gear).
any thoughts???
thanks!
