I did not download my original MR map when I first attached the AP unit to my car because I was under the impression the stock map was already on it. So if I unmarry the unit from my car, will the original, undetected by the dealer map be flashed back to the car?
Thanks

 

The AP should have saved the current map during the initial load process.

 

The AP would not save the current map unless you expressly chose to download it and, in this case, it looks like the OP did not...

 

^Fair enough. IIRC, on the older version you didn't have a choice.

 

even if you have an older accesport cant you update it and then be able to save your stock map? Sorry im a newb.

 

Per Cobb, the original map is stored on the unit and will be installed when unmarried and since there have been no official ECU reflashes for the MR, the program must be the same.
