OFT Turn off O2 Sensor Codes?
So I am fixing to install a JDL UEL header with no pre-cats. I already have an OFT and have been running it's canned tunes for years. I will be switching to the stage 2 (or whatever) tune for OEL headers after the install.
Does the OFT included tunes turn off the emissions codes set by not having pre-cats? Do I need to use antifoulers on the O2 sensors when I install or can I just install them normally? Sent from my Pixel 7 Pro using Tapatalk |

Tune disables cat related codes. You are fine with just tune.

OFT tunes for the facelifts (K00G, K01I) actually have an additional DTC (P2270) that is not found on the A01G/A01I series, which reports the post cat O2 sensor stuck lean.
That DTC may possibly trigger with aftermarket headers or preinstalled spacers, but it is not in the provided OFT definitions so it can't be disabled with RomRaider - but it apparently can be disabled using Ecutek.
