Failing inspection - SOS

[jbfj]

His mods are likely going to throw the fuel trims off enough that the monitors won't run, or at least not anytime soon. Best bet is going to be a set of OEM cats and a tune for emissions.

Think I just need OEM cats or should I get OEM headers too?

They are one piece.

O2 sensor spacers will cure 2 of those readiness prob!ems.

I just need 7 out of the 8 monitors ready so if o2 defoulers would solve O2S and HRT that would get me there

It's showing DTC's and pending DTC's I believe. It will not pass with those.

Only shows those on the stock tune. When driving on the custom tune this is the result

What are the DTC's and Pending DTC's? Something in your tune is causing the monitors not to run. Short of a different tune, nothing you do is likely to change that.

Post drive cycle on the stock tune. Seems looks like I may just need to pick up stock headers/cats and an inspection specific tune

2 of those will go ready with more driving and a cold start or 2. It just took me 161 miles over the weekend for my CAT monitor (no cats), and EVAP to go ready. I would keep driving the car, and wait long enough to either see a few more go ready, or a CEL to pop up, and then you’ll know what your next step should be.

There seems to be no rhyme or reason as to what clears O2 heater. Sometimes they will clear on a cold start, sometimes they won't clear after 5 cold starts with short drives, but will at the end of a 20 mile drive.

You’re telling me. I only have the oxygen sensor heater monitor, and oxygen sensor monitoring remaining to go ready. I believe both will go ready together. I’ve been 161 miles in 5 separate trips and 4 cold starts! I’ve never waited this long for those two to go ready. Cat efficiency actually went ready after 122 miles. I’m currently using O2 spacers with the smallest insert. Wondering if there isn’t quite enough exhaust gas helping the heater get to temp quite quick enough. I will wait though and see what happens before swapping out the small orifice insert. Not even sure if the sensor heater monitor is actually looking at the upstream or downstream O2 heaters, but I assume downstream.

After I boosted my car it took a long time for fuel and evap to go green. I think you need more drive time before you keep flashing tunes back and forth op.

You got the cat monitor to go ready without cats?

Does that mean on the custom tune I won’t pass because the monitors aren’t running and on the stock tune I won’t pass because of the DTC’s? Will the DTC’s cause the OBD2 portion of the inspection to fail or the visual/discretionary part?

Check engine light is on, pictures of codes are attached

I always do. Takes a few different combinations to try with spacers and orifices, but yes.

Those are mostly all tune related. Looks like you’ll definitely need to contact your tuner to enable all emission systems or go back to stock.

Could I drive it around as is on the stock tune and have all monitors go green or is that a bad idea? If I have emissions systems enabled will the CEL go on? Will I then fail inspection for that? No risk of failing the visual side of the inspection, just need to get past the OBD2 part
