Four steps

How it works

  1. Diagnosis and reading

    A full health check of your engine with the diagnostic tool, then your original file is read (extracted).

  2. Development

    Your map is modified to measure. In most cases, we receive the new map in less than 24 h.

  3. Writing

    The new optimised map is written back into your vehicle's engine computer (ECU).

  4. Test and handover

    A test together, parameters checked in real time (logs), then the keys are handed back.

Frequently asked questions

Does remapping damage my engine?

With a Stage 1, we respect the mechanical tolerances set by the manufacturer: we never go beyond the safety limits of your engine, turbo or gearbox.

How much does a remap cost?

Stage 1 is €490, Stage 2 €570 excluding parts, Stage 3 from €700. Gearbox, E85 and option prices are on their pages.

How long does the work take?

The work starts with a diagnosis and reading your original map. The file is then sent to be modified. Depending on the vehicle, we receive the new map and finish writing it in less than 24 h.

Can I mix E85 and unleaded?

Yes: that is the principle of the Flexfuel conversion. The engine computer (ECU) adapts in real time to the proportion of bioethanol and unleaded (95 or 98) in the tank. You can fill up with either, or mix them.

Can the vehicle be put back to stock?

Yes. We keep your original map. If you sell your vehicle or want it back to stock, we write the original file back (Back to stock option, €150).

Are the simulator figures guaranteed?

No: they are indicative figures. Every engine is different; tell us your vehicle for a quote.

Can the modified vehicle be driven on the road?

Changes to the engine map may affect the vehicle's road approval. The modified vehicle is reserved for use on a closed circuit. The customer is solely responsible for how the vehicle is used.
