Im using FN2r. Recently ive changed my air filter to simota air filter. Then the check engine appears. Ive dismantled the battery and hoping the ECU can adjust to the new air fuel ratio. At first it was ok. Then the check engine appears back. I havent tried changing to the OEM air filter yet.
My question is the ECU cant adjust to the new breath ? Do i have to use Hondata or equivalent?
Thanks,
Newby in I-vtec
