Hello, apologies in advance for any “nooby” questions.

Last summer, I bought a G37s with a MagnaFlow exhaust, Z1 test pipes and an ECUTEK tune on it. I’m coming up on almost a year with the car and it’s almost time to do an emissions test.

I took the car once and got a fail, (which I was almost certain it would, due to the test pipes). I replaced the test pipes on the car with ISR high-flow cats last week and was getting ready to take the car to be tested a second time.

I plugged my OBD2 scanner into the car (should have done this first) and noticed that the Catalyst Monitor says “Not Supported”, instead of the typical “Not Ready”.

I then opened the ECUTEK app (which I never really have) only to discover that the in-app I/M Readiness tool doesn’t even show a Catalyst monitor (which it typically does).

I’m now assuming that this specific tune on my car has the Catalyst monitors completely disabled. I have no idea who originally tuned the vehicle and can’t find any information on getting a stock tune for emissions. Furthermore, the guy I bought this car from is MIA, I haven’t been able to contact him.

Any suggestions here? Take it to a dealership and get a “reflash”? Or get a new tune?

 

Dealership won't be able to do anything since Ecutek is aftermarket so you'll need to reach out to a tuner.

Does your city/state require all sensors to be "Complete/Ready"?

I can take a look at my app and see how it looks as a reference. I believe mine doesn't have all of those items.

 

I bought a Miata from out-of-state with an EcuTek tune which had CEL, EGR and O2 sensors disabled which appeared at the inspection station. My part of the country requires all the emissions stuff to work. I booked time with an EcuTek tuner who turned on all the devices and tweaked the tune for a couple more HP. Find your local tuner, s/he will be able to check all that.

 

There should be a stock tune in the programmer. Most tuners have you do a backup. Look in your list and flash it.
