how to properly prevent p0420 from coming up?
I thought it would be as simple as unchecking the DTC box in engine diagnostics tab - however, the CEL continues to stay on without actually telling me what the code is.
hi flow cat, s/c LE5
What is the right way to do it? Don't just say "tune it out" because I don't know what you mean by that. If there is a way for the ECU to recognize that there is a hi flow cat, therefore, higher airflow through the cat is ok (thus no code), I'll do it that way. But I don't know where to change that parameter.
