o2 censors do you need to run them , if you dont what happens ? im running standed computer and a 5 speed manual box if that helps?????

The ecu needs the oxy sensors to run in closed loop mode. Some ecus use four oxy sensors like mine but I deleted the rear two and it seems to run ok.

what do you mean you deleted it? is that possible? do you have TRAC?

used the engine trans computer as a transplant into a different car. The front cut did not come with rear oxy sensors so I didnt hook any up to the rear oxy sensors input into the ecu. seems to run ok but no doubt that the computer would bring up an error code.....
