Aarons car was originally a 4 Cylinder ME2.0 Car, now with a 5.5 litre M113 V8, so that is why his best choice is the ME2.0 ML55 ECU with Julie, but he will still need to Version Code a lot of stuff to avoid Fault Codes and possibly limp modes, and ensure everything talks via CAN.
My Car is an M112 V6 SLK 320 which is ME2.8, Electronic Pedal, etc etc, and it is getting the Engine and then after testing and possibly debugging, later on the Trans all from a 2001 W220 S500 M113V8, and I will likely be using the 2.82 Ratio Diff from a C Class CDI with the V8 Trans and TCU combo.
No, I don't use any Dongle with SDS, and SDS will not change VIN unless the ECU is Virginised first, or Brand New.
What I will do is use my Programmer (KTag), to Clone the ME2.8 EEPROM Data from the V6 ECU to the V8 one, and the R170's VIN will then follow, as it is stored in the EEPROM.
Then I will use SDS to Version Code all the stuff from the W220 ECU that has different Codings, stuff like EIS from "Present" to "Not Present", Cooling Fan from whatever to whatever, etc etc.
That is exactly how the likes of Osterle and other MB Tuners do this kind of thing, although some may actually start with a Brand New ECU
HTH, Cheers Dave
Ah I see Ktag as the cloning tool.
Thanks for that bit of info.
Im installing a supercharger on a M113 55 and placing an ECU master piggyback unit for tuning.
Plan B is E55 ECU and I already have a harness handy.
Much goodness going on here when it comes to modding Benz.
Keep it up Turdo,Dave
