Siemens SIM4LE/SIM4SE

New AT Protocol!

Dear Users,

Take a step back in time with a new update dedicated to the brand with the star's iconic Youngtimers! We are thrilled to announce that the Siemens SIM4LE and SIM4SE ECUs are now officially supported on your AutoTuner Tool.

These ECUs manage the legendary 180, 200 Kompressor (2.0k), and 230 Kompressor (2.3k) engines. This is an excellent opportunity to breathe new life into these bulletproof engines or to offer highly requested FlexFuel (E85) conversions on these models.

⚡ Method: 100% OBD (Normal Read - NR) Forget about hard-to-reach ECUs! Simply plug your tool into the OBD port, read, and write. A perfect and highly efficient solution for your workshop.

• Mercedes C-Class (1997 - 2000)
• Mercedes CLK (1998)
