About remapping

The Suzuki Swift accounts for 73 files in our catalogue, with the 1.4 Boosterjet turbocharged petrol as the dominant engine, followed by the 1.3 DDiS diesel and the naturally aspirated 1.6i. It is a light supermini, and that lightness means any torque gain is felt more than usual at the wheel.

Stage 1 accounts for 60 of the 73 files, with 6 additional Stage 2. Being a light car with a modern turbocharger, the 1.4 Boosterjet offers an interesting margin for improvement. The most frequent ECUs are the MED17.9.63, the MG1CS026 and the ME17.9.51 on petrol, plus the MJD6 on the diesel versions.

Frequently asked questions

How much is felt on such a light car?

Quite a lot, precisely because of the low weight: the torque-to-kilo ratio improves noticeably, especially on the 1.4 Boosterjet turbo.

Do you cover the 1.3 DDiS diesel?

Yes, it is present in the catalogue although in lower volume than the Boosterjet. The bulk of the work on the Swift is petrol.

What is Stage 2 and do I need it?

Stage 2 assumes mechanical modifications such as intake or exhaust. If your car is standard, what applies to you is Stage 1.
