My thought process is, well, scarey if you want to know the truth....
So using the AFR (stand alone O2 sensor) to monitor AFR under normal driving conditions. Then switch on the gas and using the EFIE, adjust AFR back to the baseline.
I'm going to try running up a hill (po-boys dyno) and try adjusting there as well.
BTW this is for a 92 Jeep 4.0 HO I-6 A4 3:55 final gears, factory tire size.
