First, I'm in a 2015 335i with a VRSF catless downpipe, I already tried the VRSF downpipe fix, wired everything correctly and it didn't work, heard it only works on PWG cars and mine is EWG, not my question though and not looking to try another "fix".

Second, I am running MHD Stage 2+ and don't know if that will mess with my readiness, Do I need to flash back to the stock map?

and Third, I've come to the conclusion that i'm just going to replace my catless downpipe with my old OEM catted downpipe.

So my main question is, if I switch to the stock map on MHD, and re-install my OEM catted downpipe, will I pass emissions? and if not what do I need to do?

You’re right, the catsim will only work on PWG. Put the stock DP on and upload the stock tune then buy a $15 OBDII reader to confirm readiness. You will need to complete a drive cycle to achieve readiness, see below:

Well, I would suggest modifying the title of this thread if you want people to weigh in with the info you need, rather than search the forum for very specific terms like "VRSF" "catless", etc. People seeing the "Passing NY Emissions" title may not realize what info you really need, and may not click on the thread to see the details.

Good luck.

You don't have time read and I don't have time to write a detailed explanation either, so I'll answer your question quickly.














Maybe.

you have mhd...flash what ever tune and just drive the 50+miles within 3 cold/hot cycles at 40-60mph to get you to ready state... should be all good.. .
