not sure on the flash, but as someone already stated you will need to go through the cycles at least a few times.. if you wanna bang it out in one go do it at some low traffic hours so you can comfortably perform the cruise portion of the cycle on the merritt or 95.. took me two cycles. make sure the car has sat overnight and when you start it you only perform the cycle.. no shenanigans and no errands.. just stick stricly to the cycle directions/procedure.

make sure you have the dial setting on the dp fix correct as well.

also i had no problems in the past, but when i registered in ct everything checked out until someone decided to do a mirror test.. unless you know the guy they will likely fail you. most shops will get you on ramps so their camera can show the cat and others will do a mirror test or if you are lucky do nothing once the obd passes.. been pulled over a few times and they haven't mentioned the inspection.. lady at the dmv said they don't even bother they just care if the car is registered and visually everything checks out.. lights/tint/plates etc.

I have procede Fuel Flash for pump gas. I had no issues in map 0 and not removing the flash. Having an $18 tool like the amazon link I posted will show you readiness. If you have readiness and no obdII codes related to emissions you should pass.

I flashed my backend to stock because I wasn't seeing readiness before doing so. Like I said previously, it took me a number of adjustments on the DPFix before I got it right, so it could've just been coincidental..
