I need some help here. I've been searching everywhere and I can't seem to find a solution. I have a 2018 Honda Civic si with full 27won bolt ons including their w1 bolt on turbo, Injen intercooler, CNT racing intercooler pipes. I also have a Sirimoto flex fuel kit. So shortly after installing my 27won down pipe and front pipe I started to get the P0139 exhaust system error code so when I flashed my basemap for the W1/flex fuel setup I disabled the secondary O2 sensor but after 10k of driving I started experiencing loud sporadic banging coming from my exhaust and sometimes even sounding like it came from the motor. When I checked my sensors I would experience 2-3 knocks as well. It got to the point where I was afraid to push the car because I didn't want to blow it up. So I went and reflashed the basemap again with the sensor enabled and the banging eventually went away and I get maybe 1 knock here and there versus 2-3+ when I had the secondary O2 sensor disabled but the problem is that I still have the CEL and I'm trying to figure out a way to disable the code. It's been a nightmare trying to figure this out. I can't find it under misc or closed loop. How can I disable this code through Hondata? I need step by step if at all possible.
