Thread: SAFC2 and DE ECU not communicating well

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.

any ideas guys???

Are you 100% sure it's wired in correctly? I know you said it's good but you might want to recheck it again to be sure. Do all your gauges on it read out properly?

You can only adjust the IACV when the car is in timing mode, but not by that much. 2k RPM is a lot, make sure you don't have any leaks..

Definitely check your TPS and check your ECU for codes.

Also, wrong section (tuning!)
