jombiee,
Pls understand that i do not do programming.
So you request I cannot do.
All the chip I have..feels, jun, mugen DO NOT have the o2- disable.
Normally what is disable are the knock sensors and speed limiter.
What you request can be done but that is not the correct solution cause you Fuel consumption will be bad.
What CEL do you get? CEL 1 or 41
If this is the case the correct way is you should be replacing your O2 sensor.
I have a long PR3 ecu and have chipped it, not problems....
Pls fix your o2 sensor. TQ
