Remapping
for passenger cars

No generic file: every map is developed for your vehicle, then measured on our dyno before and after. You leave with the report.

More power, more torque, a crisper throttle response — without compromising reliability when the vehicle is standard, and making full use of your mechanical modifications when there are any. A dyno run before the work, development of the map, a dyno run afterwards: the gains are measured, not just claimed.

Stage 1

Standard vehicle

Map optimised for the manufacturer's configuration. The best ratio of gain to budget.

  • Increased power and torque
  • Mechanical reliability preserved
  • Lower fuel consumption in steady driving
  • Can be done remotely on most ECUs
Stage 2

Intake and exhaust

For vehicles fitted with a direct intake, an exhaust system or a sports catalytic converter.

  • Map adapted to the actual airflow
  • Full use of the parts fitted
  • Dyno tuning mandatory
Stage 3

Mechanical tuning

Camshafts, pistons, turbo: injection and boost are recalibrated to suit each modification.

  • Full development on the dyno
  • Custom injection and boost parameters
  • Reliability follow-up after tuning

Can't come to Boulleville? On most models, stage 1 can be carried out remotely: you send us your engine ECU following our shipping procedure, we remap it and return it within 24 to 48 hours.

Remapping starts here

You cannot write a good map without understanding the mechanics it controls. That is why we strip down, measure and know engines from the inside.

Pistons, connecting rods and rings prepared on the Techtronic workbench

Knowing every part

Pistons, connecting rods, rings: every component has its tolerances and its limits. We know them because we have them in our hands, not just in software.

Understanding the mechanics

Surface finish, running clearances, thermal behaviour: what the mechanics can really tolerate is what sets the limit on what the map is allowed to ask.

Then writing the map

The map comes last: it exploits the engine's potential while respecting its measured limits, and is then validated on our dyno.

What about your vehicle?

Estimate your diesel savings

On a standard diesel engine, a well-developed stage 1 map lets the engine work lower in the rev range, with more torque available: you use less throttle to get the same pick-up. Enter your usage and the calculator works out a realistic range.

An indicative estimate, not a guarantee. The actual savings depend on the engine, the condition of the vehicle and above all on your driving: if you constantly use the extra power, consumption does not go down. The power and torque gains, on the other hand, are measured on our dyno before and after the work and appear on the report handed over with the vehicle.

Motorsport vehicles

Rally, hill climb, circuit. From the original engine management to programmable ECUs, right through to in-race data analysis.

Emission control systems

For vehicles intended exclusively for motorsport (circuit use, vehicle not re-registered for the road) or for export outside the European Union, we can work on DPF, EGR and AdBlue systems.

This service is carried out on presentation of proof of use and after the customer has signed a declaration. It is not offered for a vehicle driven on open roads in France, where it is prohibited.

Frequently asked questions

It depends on the engine. On a recent turbocharged petrol or diesel engine, a stage 1 generally delivers 15 to 30% more power and torque. On a naturally aspirated engine, the gains are more modest. In every case, they are measured on our dyno before and after: you leave with the report, not with a promise.
On a vehicle under warranty, the manufacturer may cite the ECU modification in the event of an engine dispute. We keep your original file and can reinstall it at any time, free of charge.
Yes. The original file is saved before any modification and can be reinstalled at any time.
Stage 1 optimises a strictly standard vehicle. Stage 2 is for vehicles already fitted with a sports intake, exhaust system or catalytic converter: the map is developed on the dyno to make use of the actual airflow of these parts.
Yes, for a stage 1 on most models. Download the shipping procedure and send the ECU; it is remapped and returned within 24 to 48 hours.
On a standard diesel, yes, in steady driving: with more torque available at low revs, the engine works under less load at the same speed. The reduction depends on your journeys and your driving; if you constantly use the extra power, it disappears. Estimate your savings with the calculator.
Yes, E85 flex-fuel bioethanol conversion is one of our specialities, with or without performance remapping. See our dedicated E85 conversion page for details.
Half a day on average for a stage 1 with dyno runs before and after. Stages 2 and 3 require longer tuning, scheduled with you.
