OFT Disable P0420 Cat Efficiencty - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hey all,

I know this may have been answered many times before, but my question is in regards to disabling the P0420 Cat Efficiency error code. I am running UEL headers, catback, the 2.0x stg 2 tune (thought this would have already disabled the issue) and my CAL ID is A01I. As far as I can see there is no exhaust leaks anywhere.

I have tried to edit the tune file using the new xmls but get no option under diagnostic trouble codes for P0420? Not sure what I'm missing here.

Cheers

The defs you download from openflash don't have it and have never had it. Stg2 doesn't even have p0420 turned off.

You can get vastly better AT defs and tunes for 98RON and E85 from my thread.
