Hey everyone im do for emissions im FBO with JB4 and backend flash i flashed back to stock if i set my JB4 to Map0 will i pass !? With my catless downpipes !? I do have downpipe fix but i was wondering if anyone passed without it !?

[trohde78]

No, you will have a check engine light for the downpipes.

The check engine dont come in right away if i turn autoclear off and set it to map0 it takes 20min or around 10-15 miles so iwas hoping to do that within that period of time just not sure of the o'2s will get ready that quick

As long you will not have CEL you will be fine. I have catless DP and cobb stage 2 map and I pass emission test without problems.

Do you flash back to stock or do you just leave it in stage2 and go for test ?

I it was on stage 2 with catless dp and Dinan axle back free flow exhaust that is pretty loud. Emission guy is connecting obd cable to the car so as long you do not have any codes you're fine. As long as they will not place any sensor on the exhaust pipes on our cars we'll be fine. Let me know how the emission test goes.

Thank you for all your help, i flashed it to stock and i will put JB4 to Map0 so they can connect to the car i will try to get it done this friday

And will report back

if you flash the car, you need to let the ecu to re-check its emission systems. or else you will fail the emission test, just fyi. you might want to look up the details on this since I don't remember off the top of my head.

I believe Illinois allow for one of the monitors to "fail" or "incomplete". So if you can't get your cat readiness to come on due to your downpipe, but everything else is ok, you should be ok from my experience.

Thanks yeah i flashed back to stock about 2-3months ago so should be fine with relearning, everything else looks fine and no check engine even with JB4 in map0 with AutoClear

You used MHD or BB to flash? You can monitor the emission readiness through MHD app just FYI.

[Impac]

I use both to flash BB and MHD but ever since MHD came out i've been using it for backend flashing, i forgot MHD has that option i will check it tonight after work

So quick to assume people are idiots. I was asking for someone else. Thanks for the help though.

Even then it depends on the county...
