Hello All,
I am new to bimmerpost. And already i have a question.
I have an 2011 cpe with N55. I have recently upgraded to a larger FMIC. I also have a Cobb Accessport, however, when i tried to install a new program, I got an error , the ROM on my car is unsupported by the AP. It used to be supported. Earlier in the year, I took car to dealer for service, and they changed the rom on the car. Prior to taking the car in, I had placed stock rom back on the car. I didn't put the stage 1 back on the car immediately. So in june, I wanted to put the tune on my car and it wouldn't take. I emailed Cobb Support, and they said I need to have DME upgraded. I went to Bimmerspeed to have FMIC installed, which they did. They couldn't upgrade the DME, or perhaps do not have to machine/ tools, etc.
Has anyone seen this issue before, who do I go to to fix this, so I can can put a new tune back on my car. HELP!
