Thanks Mopar_Rich. I'm still new to EFI, but trying to learn more as I go. I might have some questions on connecting a flex fuel sensor to the FAST 2.0?
I was looking over the manual for the FiTech and the tuning options look pretty good, but the AFR and Timing matrix are only 3x3? I'm guessing the software is interpolating the 3x3 matrix at finer granularity?
