what the hell? Maf and s-AFC problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So when my s-AFC is hooked up my car (w/sr20det) runs just fine. Now when I unplug my s-AFC my car will not run, it acts as though my MAfs is unplugged. I can't rev past 2500rpm, idles rough etc.

Any ideas?

dont you have to cut the maf wire and run it through the safc, of if ti is unplugged the ecu wont get a maf voltage?
