Hello from France,
I have a 3 series 328i made in 2013 and imported from USA. It get the engine N51.
I want to tune it to stage 1 + flexfuel Ethanol E85.
Is someone here able to do that ?
N.B: there something strange, I exported the ecu file and the size is 2Gb. I have a set of ecu files that I got from internet for the same car model (BMW 328i E93), and some of those files are 256 Kb in size, other are 512 Kb. SO I wonder why my ECU file size to hight (2 GB) compared to others (256 Kb or 512 Kb). I don't have the history if this car, may be it was already tuned for something. My question is "is it possible to check the content of the file if it already be tuned or if it is an original file ?
