I got an ignorant question. If I have a chip which uses wide band O2 signal, the 5v signal wire goes to pin F14 as per instructions. But, why can I just wire the wide band to original narrow band pigtail? The only difference I can think of between the two sensors is that the wide band is a heated. The signal is the same 5v, correct? Wouldn't the ECM be able to run engine until sensor is at operating temps? I mean, it saves a basic tune.
