75563, question about A/F gauge???
Posted by nightwolf2369, Jun-03-04 09:35 AM
ok, since i got my testpipe on, i have not hooked-up my rear o2 sensor. when i get my a/f gauge, is that gonna affect it? if so, how much? thanks in advance for the help guys

iirc the A/F gauge reads the front O2 sensor. also iirc, the rear O2 sensor is basically a cat working/not detector...

Exactly. Your AF guage will read off the front O2 in the downpipe. There is a resistor mod for the rear O2 you can do to prevent the CEL from popping up on you. Rear O2 pretty much just tells you if your cat is dead or not.

Nope, blame the tree huggers for this one.
