Could any one tell me how to get my air fuel ratio on the data logs of the diablosport predator?

 

I don't know if it actually shows A/F ratio. It will show o2 sensor voltage and injector duty cycle.

 

I'm sure they leaned the curve out a bit, but it's still fat enough not to cause any troubles if that's what your worried about? i would definately stick to the reccomened fuel for which ever tune you have.
This is probably a question that should be posted in the Diablo forums which is found directly off the Diablo site itself. Mike can answer that better than anyone here. That tuner just came out.
