Which engine gains most?
The 0.9 turbocharged petrol, by a clear margin. The naturally aspirated 1.0 gains considerably less, since there is no boost to adjust.
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.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
