PC 3

i just have a real quick question for you mike ..... does the pc now let you shut off the O2 sensers? like the race tuner does so you can run the older exhaust w/o the O2 ports in the exhaust ?

The new USB PC does in fact defeat the closed loop O2 sensor feed with an "O2 eleminator" that plugs into the sensor harness plugs. It basically flat lines the signal to the ECM so that no offset occurs. I'm not real sure how they deal with the Bias values uless they just let them go to where they will and stay there. When installing older exhaust systems, watch for clearance problems with the transmission top and side covers. Also the trans mounting brace is different on 6 speed models.
