Cat Monitor Not Supported

nick654

OP,

I literally just had this same issue with emissions. You have to call dynosty, tell them you had a tune and need to pass emmissions. Hal will email you a file that has all monitors turned on and then you upload it to the car with the ecutek cable. I am not sure if you have to buy your own individual cable though so you should ask about that. Also, once you flash the car you will need to drive the car to set the ECU readiness. There is a readiness monitor in the ecutek software that will let you see when the systems are ready. I let the car initially warm up to about 180-190F then drove 10 min on the highway going 55 mph (sets cat readiness) then you need to do a bunch of stop and go driving ex. driving 30mph for 2 min and coming to a complete stop multiple times. It seems like a hassle but from uploading the factory tune to setting ECU readiness it took maybe an hour.

Hope this helps

Update:

I passed emissions today after reflashing the car to stock and setting readiness.
