Is it possible to turn o2 sensors off with racer tuner? I have a 09 flhx with 2011 ecm and throws codes for inoperable o2 sensors because of change in sensors and ecm.thanks Pete
You can go to the main AFR table and change any of the settings that are bold to not bold (basically richen them up) and it will no longer run in closed loop. I believe the ecm still looks for the sensor to be connected though so it will still trip a code.
