Mercedes-Benz CLK 220 CDI Stage 1 Remap
On Mercedes-Benz CLK 220 CDI diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. 220 CDI engines with 136–150 bhp reach 180 bhp with a Stage 1 remap; the largest gain is +44 bhp (W209 220 CDI 136hp). Pick your version in the table below.

GP Power ECU applies the software at its workshop in Hukou, Hsinchu, using EcuPrime-developed files; workshops can also order the file directly.
About the Mercedes-Benz OM611 / OM646 / OM647 CDI (pre-2008 200 / 220 / 270 / 320 CDI)
These are the first-generation common-rail diesels of the W203 C-Class, W210 and W211 E-Class, Vito, Sprinter and ML. Known for their durability, they respond reliably to a remap even at high mileage.
How a Stage 1 remap works on the Mercedes-Benz CLK 220 CDI
Stage 1 recalibrates injection duration, rail pressure and boost. With simple emissions hardware on this generation the calibration focuses directly on the engine; the mid-range torque gain is clear.
Pre-remap checklist
- Injector sealing and injector seals (burning smell and carbon traces).
- Oil leaks at the turbo and intake hoses.
- EGR valve cleanliness.
- Automatic gearbox oil and filter service.
