VF650 SC kits having issues in MA?

Anyone familiar with folks not being able to pass inspection in MA with this kit because of tune issues? Someone mentioned that me but wanted to verify on here.

Hey guy. From what I heard you swap out exhaust to stock (for the cats and readiness) and swap over to stock map to pass emissions. That's what ESS told me.

I have a ESS but same pricipals... You are most likely not passing due to catalyst readiness. Your tune may have that turned off to eliminate a cel on a car that has the primary cats removed.

Also I am not sure about vf but ess provided me with a separate tune with a 5000rpm redline to flash into my car and drive it for a few hundred miles to get all readiness monitors to pass.

Readiness can be checked on any simple obd2 scanner so once you see that they have passed you go for your sticker. You may need you factory xpipe, high flow cats, or secondary o2 sensor spacers to get the car to pass the catalyst testing.

Surprized at this problem

MA allows one flag not ready. So if your tune disables cat efficiency codes (so as to prevent the CEL light), you'll have "cat not ready" or "cat incomplete" but all the rest should set and you should pass.

Check readiness as eatsleepboost suggests and see what the issue is, if any. Just remember that everytime you reset codes with the scanner, all emission-related OBDII flags will reset and become not ready. Sometimes it can take a while for everything to set again, particularly (in my case) evap

This is because there are two readiness for cats. Not one.

Correct me if I'm wrong;

There is an "oxygen sensor" flag which reports the functionality of the the sensors upstream of the catalytic converter and a "cat efficiency" or "catalyst" monitor which reports on the downstream sensor function.

Upstream sensors are critical to the operation of the engine which relies on them to report A/F ratio.


Downstream sensors are not critical to engine operation and are solely present to verify normal function of the converters

No tune would spoof or otherwise monkey with the operation of the upstream sensors and the "oxygen sensor" flag will always set. The "cat efficiency" flag, on the other hand, is purposefully disabled so that users with test pipes do not have suffer constantly lit CELs. Therefore, the "cat efficiency" flag always reports not ready.

Anyway, I have a VF620 with VF stock tune and test pipes. I have one not-ready flag, "cat efficiency", and I pass inspection.

So you have secondary cats? I think that helps, no?

Dpaul your post is correct except in MA you are allowed to have 1 "not ready" non-continuous monitor. Since the cat monitor is continuous it has to be ready to pass. An evap rediness can read "not ready" and still pass.


Secondary cats don't help anything inspection wise. They are after the rear O2 sensor. They wouldn't only help if inspection stations did an old school test and put a sniffer on the tail pipe but that is no longer done.

Not sure I follow. Yes, as I stated in post #4, MA allows 1 not-ready monitor. However, I don't think a distinction is made between continuous and non-continuous monitors.

My experience has been that a not-ready cat efficiency monitor will pass MA inspection, if all other monitors are set. I have done this many times, at several different inspection stations, over the last decade, with three vehicles that were tuned and lacking converters.

However, I was failed when I showed up with both cat not-ready and evap not-ready. To be sure, this case involved a tuned E90 335xi, not the M3, but that shouldn't make any difference.

Perhaps it was just the inspection station that I used. I was forced to remedy the evap problem.

I do have them (I think!) but as eatsleepboost points out, they wouldn't help
