if you turn the sensors off via the tune you won't pass emissions as they won't show on the readiness monitors

That is correct. Thats why I'm trying to figure it out I can reset every few months if ce shows up but not every 30miles.

When I get new spacers I'll let you guys know if that solved the problem. If not could be faulty o2 sensor.

I don't want ce light or swap top stock exhaust when going for emissions

Just a thought, why dont you get your tuners to write a separate map accessible from the cruise control (like APR) that will get you through your emissions tests

are your o2 parameters turned off or down? there is a difference. when you turn the sensativity down, they will read less oxygen and less likely to pop a cel.

i live in NY, we are allowed 1 readiness code not ready.
