BEFORE WE START

M111 tuning
FAQs.

Will this work with my Mercedes?

The project focuses on Mercedes M111 200 and 230 Kompressor engines with Bosch ME2.1: C200/C230 Kompressor (W202), CLK200/CLK230 Kompressor (W208) and SLK200/SLK230 Kompressor (R170). The ECU version determines compatibility. Send your ECU or software reference so we can confirm compatibility.

How much does a remap cost?

Quotes depend on the software version, modifications, selected options and scope of work. Tell me about your setup for a tailored proposal.

How much power can I expect?

Project estimates for the 230 Kompressor are approximately 220 hp for Stage 1, 220–230 hp for Stage 2 and 230–250 hp for Stage 3. These figures cover the described hardware and calibration together. Results depend on fuel, installation and engine condition. The 200 Kompressor is assessed individually.

Can I choose individual tuning options?

Yes. Contact Daniel directly to discuss the features that interest you. The final combination is agreed after reviewing your ECU software and setup. Immo off is currently experimental for 114.235404.04 (404) software.

Are the dashboards free without a remap?

Yes. The PC and Android versions are free and independent of the paid tuning service. Both include a demo mode to explore the interface without connecting a vehicle.

What do I need to connect the dashboard?

A compatible ECU, an ELM327 adapter that supports the required commands, and the appropriate vehicle connection. OBDLink, Veepeak and Renolink have been tested. Some inexpensive clones are incompatible. The repository includes connection instructions.
