Hi, Justin, I recently bought a pro racer from yyou and also bought a big air maf (My car is a saleen"06 ,from Puerto Rico) I have some questions about the timing in my jdm tune, why the car is running at 10.8 to 11.3 a/f ratio and at about 5,500 to 6,000 rpms the a/f ratio goes up to 14:confused: any help will be appreciated.

Hi, you could be out of fuel pump, injector, the maf could be pegging, or it could simply be a tuning issue. We'll need more data to figure it out. Log injector pulsewidth, maf voltage, rpm, load, spark, fuel pressure, and fuel pump duty cycle.
