Spare ECU question
This goes out to the few of you with spare ECUs. Is the ECU the same for the entire 6.2 line? I was reading somewhere that customers in Germany can get the S/SL 63 tune loaded for their C63. When buying the spare ECU, can you simply get the S/SL tune loaded? Or are the parameters far off due to the difference in exhaust? I suppose they will need the VIN from the S/SL, but I wonder if you know someone in parts/service, you could probably just get any VIN from an S/SL?
