Hey guys, I purchased this shitbox about a month ago and have yet to pass emissions. RBC intake manifold, Full Race catless DP to a magnaflow muffler. Bought a hondata and running a base map with all sensors turned on. No CELs but I cannot get the oxygen sensor or cat monitor readiness set. I’ve done about 120 miles of mixed driving and deliberately aiming to do the specific drive cycle for this car. Have a 90 degree defouler and confirmed downstream o2 sensor is working by comparing voltage reading through the drive cycle.

Anybody had a similar experience? If so, how did you get these monitors set?

If I can’t get them set in the next 50 miles or so, I am reverting to stock dp (once I find one) and flashing a basemap. And no I can’t move to an emission free county. Any CONSTRUCTIVE feedback appreciated, TIA!
