C44 After Exhaust and Flash
I just got everything put back together and after going down the road a bit the CEL came on and it's indicating issues with the o2 sensor. If you have a 2018 or newer make SURE that the o2 sensor is disabled or you are going to get the CEL coming on. I am pretty sure I am going to have to ship it back to Danos for a reflash to disable the o2 sensor.
Has anyone found a working plug for the o2 sensor? I have combed the forums and the closest I found was a optimizer from Dynojet.
If you are experiencing surging/hunting/loping after a full exhaust system is installed the o2 sensor should be disabled. If you have a 2017 or older you can just buy an eliminator kit, if you have a 2018+ you need to have the o2 sensor disabled in the ECU through flashing. You should buy a plug for the port on the exhaust as well because leaving the o2 in with the system disabled can damage the sensor. (It is a ~$150.00 part that you can sell or give away, don't destroy it when a plug costs 6.99 on amazon)
