Hijacking this thread, anyone know of a good shop that can update our ECU? From what I hear, all "tunes" are just tweaking some values/tables in the ECU, it's not all new software (this is why all tunes are "adaptable" because they're using the bmw software that adapts). So for this reason it's probably a good idea to get the latest version of the ECU firmware before doing the tune. All dealerships around here seem to suck, but maybe someone "knows someone" (looking at you gferil).
