Re: How to tune out rear O2's with hp tuners ??
You'll want to go through the DTC list and find all sensors of both bank 1 and bank 1 that are labeled as Sensor 2.. Sensor 2 indicated the rear sensor
You will want to leave the DTC On/Off flag as it is, but will want to set the error mode to "No Error Reported".
