2017 FK8 Rev Match and Emissions Error

Post by jhl0609 »

Hi,

Hondata newbie here. Got my FK8 tuned and it was kind of a set and forget thing because it just always just worked. Now come time for my emissions (VA) but I didn't pass because I completely forgot about my tune, didn't pass readiness check due to my PRL high flow cat. I tuned the car back to base map and drove it around to cycle through to get all my readiness checks but the car started throwing CEL rev match and emissions error.

The error it seems to throw is P0420 catalyst system efficiency below threshold (bank 1). I can clear DTS but that also clears all the readiness checks that it's already done, kinda a catch-22.

Any help is greatly appreciated
