About remapping
The Mercedes-Benz SLK accounts for 296 files in our catalogue, entirely petrol: the supercharged 1.8 Kompressor units badged 200K and 230K lead, with the 3.0 and 3.5 V6 above them. It is a compact folding-hardtop roadster with a distinctly relaxed character.
Stage 1 makes up 257 files, with 36 Stage 2 and 22 speed limiter removals. The ECUs are Mercedes' own SIM4LE, SIM4LKE, SIM4KLE and SIM271, plus ME9.7 on some units. All work starts from the original read of the ECU.

What does the Kompressor supercharger add?
It gives a very linear delivery available from low revs, and responds well to electronic work — more so than a naturally aspirated unit.
Do you cover the V6 versions?
Yes, the 3.0 and 3.5 V6 are present in our catalogue, though the supercharged four-cylinder units lead on volume.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
