Thread: SAFC fuel adjustment backwards???

I have a VE motor that was recently swapped along with SSAC header, WAI intake, VE injectors, DE MAF, and DE ECU with SAFC 2.

When I unplug the SAFC2 of course it runs pig rich, but when I plug it back in and have the 6in and 6out but ZERO on the lo and hi throttle fuel, it leans back to about 12.5-13 during idle; however, when I start to lean the sucker it starts getting richer! However, when I ADD fuel it does NOTHING, not even run pig rich. The wiring looks good, so I don't think it's that, and the MAF USED to be reversed where the car wouldn't run at all, so I reversed it back to the correct direction. oh and also, the car just started to rev up to like 2krpm and stayed there, no matter how I adjusted the IACV. I have unplugged the battery and will let it set like that for a while.

any ideas guys???

idk but read this it might help

Damn thats some good info right there! SAFC Install and Tuning

Sounds like the problem isn't with the SAFC if you ask me.. try not just unplugging it (since you've effectively disconnected your MAF by doing so) but actually re-connecting the MAF wires to each other? Could be a PITA but you only have to cut the one wire, and leave the others hooked up. Remember that SAFC only controls the airflow signal to the ECU, so no matter what the ECU thinks it is, it isn't going to be idling at 2k solely because of that signal. Something else is up at the same time.

fixed it. the MAF was on backwards.

Whoops!

Indeed Indeed...

it was an honest mistake by my buddy.
