Dealer update!
Make the legends roar! We are extremely proud to announce that the famous Siemens MSS52, MSS54, and MSS54HP ECUs are now officially supported on your AutoTuner Tool.
This protocol opens the doors to the BMW Motorsport hall of fame. It allows you to work on the mythical naturally aspirated inline-6 and V8 engines that forged the brand’s reputation in the late 90s and early 2000s. Today, these vehicles are highly sought-after collector cars whose owners often seek refined optimizations (rev limiter adjustment, drivability improvements).
⚡ Method: 100% OBD (Normal Read – NR) Respect the integrity of these collector cars! You now have a solution that allows you to read and write these ECUs directly through the diagnostic port, with no tedious bench work or removal required.
Supported Highlights:
BMW M3 (1998+) – 3.2i (M)
BMW M5 (1995+) – 4.0i
BMW Z4 (2002+) – 3.2i (M)
BMW Z8 (1999+) – 4.0i
