AFC hack question at IDLE!!!
Okay i got dsm 450cc injectors on the V-AFC... i'm not sure if my Air/Fuel ratio gauge works but at idle it says EXTREMELY rich even at -%50 across the board for LO-TH on the V-AFC. is this right? let me know for sure

Re:AFC hack question at IDLE!!!
That gauge is ----. It isn't worth looking at unless you are at WOT because the ecu is doing so much adjusting and ----.
That doesn't sound right though. Mine bounced all over hell. Are you sure you have it hooked up right?

Re:AFC hack question at IDLE!!!
like i said i dunno if its hooked up right on my 91 si wire harness isn't it the WHITE wire? cuz for OBD-0 on these engines the o2 sensor is just 1 wire.. or that i use or know of.... if not, what other wire is there?

Re:AFC hack question at IDLE!!!
I don't think the AFC touches the oxygen sensor wire at all? Or are you talking about the accuracy of your gauge?
Don't trust those at all. They won't give you a reading worth a ----.
How are the RPMs at idle? Also does it SMELL like you're running rich?

haha well..... right now i'm on an open downpipe, the downpipe should be made in a week hopefully. i think in the AFC FAQ it says at only HI-TH on the AFC... what about LO-TH? also what wire do i hook up the A/F gauge up to on my 91 si wire harness... the white wire? thats the wire i use to hook up the o2 sensor.. no CEL.

I'm not sure what color your O2 sensor wire is, so I won't attempt to guess. On my OBD2 it was brown I believe, or purple. ---- if I remember.
You want to set both your hi and lo throttle to -40% and adjust it bit for bit at each RPM interval.
The general 'cross over' point is at 75% because I think thats when the ECU actually considers you switching from lo to hi throttle.
