Hondata

I removed the secondary o2 since it was disabled already on the OTS map from Hondata for an 2018 FK8

Running 91 Basemap with PRL bolt ons

I figured since the secondary o2 was not being used I could use the bung and run a wideband to monitor with a AEM UEGO gauge.
Originally I cleared the code but the CEL came back with revmatch issues. I plugged the O2 back into the harness as I thought the harness detected this (Noob not sure if it makes a difference) and it went away after about 4-5 key cycles, the CEL came back giving me a error code p2270

I was wondering if Hondata can cancel this and would this affect the car at all?

Any help would be appreciated
Thnanks in advance!

Have you disabled that DTC code in the big list?

So I followed your instructions, disabled P2270 and also P0136, tried it again and it's gone away. Ive only had one key cycle, will revert tomorrow if this has taken care of the issue.
