How do you know what A/F ratio you are running?? Is there a formula to use--using numbers from LT1-edit and the logging software??

Thanks,

Mark

 

The only real way to tell what the cars A/F ratio is buy using a wideband O2 sensor. But if you want to know what you have the PCM set for- Open loop can be figured out in the %chanfe air/fuel Vs. rpm table of tunercat. That table is for WOT, there is a formula that you have to use, look in the calibration help section, it will tell you the formula there.

 

What about for LT1-Edit??

 

Not Sure.
