#318058 What does the pre cat o2 sensor actually do on a d16? Currently my car is running without one and on a automatic ECU which I am replacing with a chipped ECU should I buy and install a o2 sensor or can I have them turn it off in the ECU before I get it? I have no problem doing whats best for my car but if its not really needed then I wont.
