So iv got a 07 335 that im trying to do the flash on. Car was bought about 2 years ago w/ mods from a girl. She has no idea if the ECU had been flashed already since she also bought it w mods. Anywho im getting an error while trying to read the ECU intitially. Cant be voltage because I even hooked another car up and kept the Volts at 13.2 during the read. Some people say switching a laptop will help (preferably older model) but before I do that does anyone else have any other suggestions or way of veryfing that my ECU is not stock? anyway I can check with the JB4 interface or BT Cable? thanks!
Oh and Program Reads "File read from ECU not valid,do not use" ill try and attach a photo.
