    Hey everyone, a friend of mine has a 96 prelude that he races at a local dirt track in the mini-stock class. lately hes been running into the ECU throwing codes and it's killing the cars power. The codes for the O2 sensors on the car and I remember hearing something about o2 sensors getting clogged up from running 110 octane gas. I was wondering if theres any way to take the sensor out and running a resister in it to trick the ecu into thinking nothing is wrong (I know you can do it with the AIT sensor). If anyone knows anything about this please help me out. Thanks.

    its definitely possible, but i dont know how to do it. .45 volts is the reading it needs to be.

    HO2S Sensor voltage (with engine at operating temperature):

    At 3000 RPM ------------------------------------ 0.5 Volts
    During deceleration from 3000 RPM ------Below 0.5 Volts


    Hope this helps

    convert to obd1 (as simple as buying a harness and an obd1 computer) and burn a chip that disables the o2 sensors so it always runs in closed loop. problem solved.
