Car cant idle with AFC Hack.

[gettocrx]

I just finish put in my dsm blue top 450 fuel injectors and a apexi vafc2. I set the low throttle from 1000-8000 rpm to -40% and the high throttle 1000-8000rpm
-40%. but seems it cant idle @ 1000 rpm unless the curve is set between -20% and -25%. anything less then that will idle rough and will throw code43 (fuel supply). Is this normal? I'm i running lean? what should I do? I have the rest (1500-8000rpm) all set -40%.

you should hit up a dyno with a wideband 02 and tune it.

dont go by internet settings.

I think it might be with my set up setting for the vafc2! What do I put in for sensors in and out for the d16z6? I have it at 6 in and 6 out! do you think this could why?

wtf is 6 in and out?

6 in 6 out is correct for the sensors on honda... Also needs to be 4 cylinder UP... are you sure they are dsm 450's you have? What is your fuel pressure at? What is the car's setup?

save yourself the pain and sell the AFC. you could ge a chipped ECU, some chips and be a lot happier with Uberdata for the money.
