I flashed MHD stage 2+ for the first time and people say it takes 30-45 minutes for the very first flash but it flashed in 8 minutes. I'm using a cable straight from bimmergeeks. As soon as I flashed and started my car it was misfiring like crazy even through I never got codes for a misfire and so I immediately flashed back to stock and put a regular code reader on it and got code U01000 and U0001

U0100- lost communication with ECM/ PCM "A"

U0001- high speed CAN communication bus

Yeah my battery was fully charged and on the charger. My car does have a software update but I doubt that's the problem. I know my coils are bad so I'm have new ones coming in maybe that's why it was misfiring bad.

Did you ever resolve the issue? Have a 335i n55 that was flashed to stage 2+ and it worked fine but after I flashed it back to stock so I can sell it, the same codes appeared for me.

My code disappeared really fast. I think it was just from flashing the car

That's good that it worked out for you. I threw MHD an email about it as the code seems to still persist.
