What A/F ratio does everyone run at idle? I just put a wideband in my cobra and at the rear o2 sensor location at idle, my car is idling at about 10.2:1 which seems incredibly rich to me. It idles ok but you can definatly smell the rich burn.
Thats what I figured. I just fired off a question to fastlane motorsports who built the car. The driver side front O2 sensor is not installed, it is zip tied to the downpipe because the coolant pipe interfears with the bung, and I now wonder if the tune was using the drivers side rear o2 I removed to install the wideband o2 sensor.
I am new to the mustang world and came over from a supra with an AEM standalone so I am trying to pick up SCT tuning as quickly as I can.
