On a tractor unit covering 100,000 km a year, a few percent of fuel consumption add up to several thousand euros. We develop maps tailored to your actual use: long haul, regional, tipper, tanker, crane rigid or recovery.

What you gain:

  • Lower fuel consumption — a typical saving of 5 to 10% depending on use, route profile and driving style.
  • Torque available lower in the rev range — fewer downshifts on hills, under load and when pulling away again.
  • Smoother driving — linearised throttle response, less driver fatigue.
  • Removal of factory limiters where they have no technical justification on your configuration.

How we work:

  • Reading of the original ECU and backup of the file before any work.
  • Development of a bespoke map, not a generic file bought from a catalogue.
  • Testing on the dyno or validation under load, depending on the vehicle.
  • Work completed in a few hours, with no extended downtime. We visit your depot anywhere in France from 5 tractor units.
  • Return to the original file possible at any time, free of charge.

Emission control systems: our maps are developed while retaining the original emission control systems and the vehicle's compliance with its type approval.

Indicative estimate provided for information only. The actual saving depends on the engine, the gearbox, the duty profile, the load factor, the weather and above all the driving. It is measured on your fleet after the work, based on your own fuel consumption records. No saving is guaranteed without prior measurement.

Race truck preparation

From the bare chassis to the dyno run, right through to trackside support on race day. What we develop in motorsport feeds directly into our work on your operational vehicles.

Wiring and electronics

The vehicle is stripped right down to the chassis for a complete rebuild of the wiring harness and the installation of our in-house electronic modules.

  • Complete wiring harness rebuilt from new
  • Electronic modules developed by Techtronic
  • Race-specific CAN network and sensors
  • Integrated data acquisition

Engine development

Every map is validated on our dyno, not estimated. The measurements are quantified and repeatable.

  • Injection and fuel flow mapping
  • Boost pressure and turbo selection
  • Air, coolant and oil thermal management
  • Monitoring of the regulatory speed limiter

Support and data

We are in the paddock on race weekends, with the truck's data right in front of us.

  • Data acquisition and lap-by-lap analysis
  • Set-up changes between heats
  • On-site electronic diagnostics
  • Monitoring of temperatures and pressures

Frequently asked questions

On a vehicle still under manufacturer's warranty, the manufacturer may cite a modification to the ECU in the event of a dispute over the engine. We tell you this clearly before any work, and we keep the original file, which can be reinstalled at any time. Most of our customers have work done on vehicles that are out of warranty.
Yes. The original file is read and backed up before any modification. Returning to the factory configuration is possible at any time and free of charge.
Allow a few hours for a standard job. For a fleet, we schedule the work vehicle by vehicle so that your operations are never brought to a halt.
For a single vehicle or a small fleet, the work is carried out at our workshop in Boulleville in the Eure department, between Le Havre, Rouen and Caen. From 5 tractor units, we come to your depot anywhere in France.
Most often between 5 and 10% depending on the engine, the duty profile, the load factor and the driving. A vehicle already run efficiently by an economical driver will gain less than a vehicle working laden on hilly routes. We rely on your fuel consumption records before and after to measure the actual result.
We retain the original emission control systems and the vehicle's compliance with its type approval. A vehicle treated in this way passes its roadworthiness test as normal.
Scania, Volvo, Renault Trucks, DAF, MAN, Mercedes, Iveco, as well as rigid trucks, construction plant and agricultural machinery. Tell us the make, model and year and we will confirm feasibility before any travel.
