Smart Roadster ECU remapping

26 files available

About remapping

The Smart Roadster accounts for 26 files in our catalogue, entirely the 0.7 turbocharged three-cylinder petrol including the 61 hp version. It is a tiny rear-engined two-seat roadster, unusual in every respect.

Stage 1 makes up 22 files — a very clean profile — with 2 Stage 2. The ECUs include MEG1.1, MEG10/11, MAG1.1 and ME17.9.20 references. Being a very small engine, the relative gain is proportionally noticeable on a car this light.

Frequently asked questions

Is a remap worthwhile on such a small engine?

Yes, precisely because the car is so light: the relative gain in flexibility is noticeable in everyday driving, particularly when overtaking.

Does it affect the automated gearbox?

The work is done on the engine ECU. On this model we work with particular care to keep delivery within what the automated transmission handles well.

Is a remap worthwhile on a car of this age?

It depends on engine condition. On a well-maintained example it responds well, but remapping does not compensate for wear.
