My friend is going to let me borrow his wideband the Innovate Lm-1. I have the Apexi SAFC II. If I hookup the wideband and tune my car then when he wants it back are my air fuel ratios going to be the same because I tuned it with the wideband O2 sensor and im going to be plugging the stock narrowband O2 sensor back in?


My car is S4 turbo II.

 

i am not positive but im pretty sure it would still be tuned correctly sence you are chaning the settings in the AFC. i think as long as the AFC didnt change. i think it would be the same. * but i am not positive. *
