Custom enginemapping
Engine and gearbox tuning designed for your car and your use, on road as well as on track, by an engine engineer based 700 metres from the Paul Ricard circuit.
- Workshop in Signes (83)
- 700 m from the Paul Ricard circuit
- Official BMW M France partner
Every map is calculated for your car, never copied from a generic file.
Our engine engineer tunes the engine and gearbox case by case, based on your car and your road or track programme. Tell us about your project.
How a custom engine mapping unfolds
- ▸ Initial diagnostic
- A full electronic read of the engine and a mechanical condition check before any work begins.
- ▸ Engine mapping
- Individualised tuning of engine parameters based on your car and your road or track use.
- ▸ Gearbox mapping
- Optimised gear shifts when the transmission allows it, in line with the engine tune.
- ▸ Validation and checks
- Post-tune verifications to confirm the expected behaviour on road or in track conditions.
Our approach to custom engine mapping
Engine mapping is about far more than loading a power file. At Bernis Factory, every tune starts from your car and the way you use it, on road, on track or both. Our engine engineer maps the engine and gearbox case by case, never reusing a generic setting that would ignore the car in front of him.
This bespoke logic applies to the high-end sports cars we work on every day, from Ferraris to BMW Ms, including Mercedes AMG, Porsche and Nissan GT-R. The goal stays the same: to achieve consistent, reliable behaviour suited to your driving, rather than a single power figure shown on a dyno.
Custom mapping or generic remapping: which should you choose?
A so-called generic remap relies on a standard file, identical for every car of the same model. It ignores the real condition of the engine, the fuel used, any modifications already fitted and the way you actually use the car. A custom map, by contrast, starts from your vehicle: our engine engineer measures its behaviour and calculates every parameter according to your driving, on road as on track.
For a sports car that runs both on the road and at the Paul Ricard circuit, this bespoke approach is what guarantees consistent, reliable behaviour rather than a mere power figure shown on a dyno. Every engine remap carried out at Bernis Factory is therefore handled case by case, never reusing a standardised setup.

Engine mapping and the Paul Ricard circuit
A large part of the mapping we carry out revolves around the track. Our workshop is located 700 metres from the Paul Ricard circuit at Le Castelet, which lets us adjust a tune to a track-day programme and support owners before, during and after a day on track. We are an official BMW M France partner for track support and recommended by ORECA, and our team has a recovery truck to step in directly on site.
Custom engine mapping in Signes
Bernis Factory is located at 26 Allée de Dublin in Signes, in the Var. This setting right next to the Paul Ricard circuit shapes our business and the way we approach engine mapping. Whether you are an enthusiast from the region or passing through Le Castelet, you will find a workshop that ties together three complementary trades: maintenance, preparation and restoration of high-end sports cars.
Frequently asked questions about custom engine mapping
- What is custom engine mapping?
- It is a tune of the engine electronics calculated specifically for your car and your use, rather than a generic file applied to every vehicle. At Bernis Factory, our engine engineer tunes the engine and, where possible, the gearbox, case by case.
- Which cars do you carry out engine mapping on?
- We work on the high-end sports cars we prepare every day, such as Ferrari, BMW M, Mercedes AMG, Porsche or Nissan GT-R, for both road and track use.
- Is the mapping suitable for track use?
- Yes. Our workshop is 700 metres from the Paul Ricard circuit at Le Castelet, and we adapt the tune to your track-day programme. We are also an official BMW M France partner for track support.
- Do you also map the gearbox?
- When the transmission allows it, we optimise gear shifts in line with the engine tune. Everything is studied together to keep behaviour consistent and reliable.
- How do I get a quote for custom engine mapping?
- Tell us about your car and your project through our contact page. We will study the most suitable tune for your vehicle and your use together, with no standardised answer.
- Custom mapping or generic remapping, which should I choose?
- It depends on your goal. A generic remap applies the same file to every car of a model, without accounting for its condition or your intended use. At Bernis Factory we work exclusively bespoke: our engine engineer tunes each car case by case, for consistent, reliable behaviour, on road as on track.
A workshop dedicated to custom engine mapping in the Var
Finding a workshop able to deliver genuinely custom engine mapping, rather than a simple generic file, is rare. Much of what is offered out there sticks to a standard tune, when every high-end sports car has its own requirements. Bernis Factory approaches this work from its Signes workshop, with the eye of an engine engineer used to mapping engine and gearbox case by case.
This mapping is part of a wider approach to preparation, alongside the maintenance and restoration of sports cars. Right next to the Paul Ricard circuit, the workshop supports both owners who care about how their car behaves on the road and those aiming for track use, without ever pushing beyond what the vehicle can truly handle.
To deepen your understanding, how engine mapping works is detailed in our guide. If you'd like to go further, our engineers can reprogram the ECU of your vehicle on the dyno in Signes.
