Has anyone on here been able to pass MA inspection on a obd2(plug in)test? I have 2 PCM one tuned and one stock and they will not pass. On the stock one i have a code for the EGR p0400 and then one for no activity from one of my o2 sims,p0160 i believe. On the tuned one the only code i have is the o2 code. I really need the car to pass and need to know the best way to get it to pass. I also have a bunch of systems showing not ready.

This is a good discussion of the GM drive cycle and rediness.

I just passed CA emmissions with all the stuff in the mods list except
for swapping in a tuned OBDII PCM. I just barely passed, but at least
I made it.l

 

so what should i do? just run though that process? I'm pretty sure the light will turn on. I took it out for a ride after clearing the code and only got 33 miles before it came back on, and non of my systems were ready

 

Well i failed again. Im thinking of sending my PCM to pcm4less to see if they could tune it to pass. anyone think they could?
