On-board electronics,
from the workshop to the track

TECHTRONIC is a Normandy-based company specialising in vehicle on-board electronics: ECU repair, engine remapping and development of custom engine management. From city cars to racing trucks, everything that goes through an ECU goes through our workshop in Boulleville, in the Eure department.

We work with private customers and professionals alike: garages, dealerships and companies with a fleet, on cars, vans, heavy goods vehicles and agricultural machinery. And our first instinct is to repair rather than replace: an accurate diagnosis identifies the exact origin of the fault, which very often avoids buying a new part. A single point of contact supports you from the analysis of your needs through to completion, with one simple requirement: a solution that is durable, effective and transparent.

What sets us apart: we do not just program, we measure. Every vehicle is validated on our dyno, and the maps we develop in motorsport — up to the French Truck Racing Championship — feed directly into the work on our customers' vehicles.

Our history

2009

TECHTRONIC is founded

The workshop opens in Boulleville, with its two founding trades from the outset: automotive electronic repair (ECUs, ABS, instrument clusters, immobilisers) and engine remapping.

2012

First electronic design

TECHTRONIC develops its first on-board electronic module for cars. The custom development division is born.

2015

First car dyno

The workshop acquires its first dyno: from now on, every remap is measured before and after, with a report to back it up.

2019

New building and HGV dyno

Construction of a dedicated workshop equipped with an HGV dyno: trucks, tractors and machinery are measured just like cars.

2024

First HGV electronic design

Our development expertise reaches a new milestone: the first electronic modules designed in-house for heavy goods vehicles, notably for truck racing.

2025

Podium in the French Championship and car dyno

A double milestone: a podium in the French Truck Racing Championship, and the installation of the car dyno alongside the HGV dyno. Cars and trucks are now measured under the same roof.

Three business divisions

Electronic repair

Repair and exchange of your faulty units, tested and guaranteed. A cost-effective alternative to a new part.

  • Engine ECUs, BSI, UCH, instrument clusters and dashboards
  • ABS / ESP ECUs, automatic gearboxes, airbag modules
  • Immobilisers, keys, key cards and various modules
See this division

Engine remapping

More torque, more power, less fuel — measured on our dyno before and after. Cars, agricultural machinery and HGVs, with on-site visits for fleets throughout France.

  • Stage 1, 2 and 3 on the dyno
  • E85 flex-fuel bioethanol conversion
  • Optimisation of torque and drivability
  • Petrol, diesel, vans — maps adapted to real-world use
  • HGV fleets and agricultural machinery
  • Adaptation of electronic functions where regulations and use allow
See this division

Custom development

OEM or programmable engine management, electronic modules developed in-house, dyno tuning and data acquisition in racing.

  • Rallying, hill climbs, circuit racing
  • Racing trucks — French Championship
  • Wiring looms and on-board electronics for motorsport

Racing as a laboratory

For us, motorsport is not a showcase, it is a permanent test bench. The constraints of racing — reliability, temperatures, technical regulations — force us to understand engines more deeply than any workshop job would. This know-how then filters down to every customer vehicle.

Our truck preparations

Our approach

Electronics are now at the heart of how vehicles work. The failure of a single ECU or module can cause major malfunctions, or even leave the vehicle completely immobilised. That is why every job at TECHTRONIC begins with an accurate diagnosis, to identify the real origin of the fault before proposing the most suitable solution: repair when it is technically possible, replace only when it is necessary.

In remapping, the principle is the same: no generic maps. Every vehicle — petrol, diesel, van, HGV or agricultural machine — is analysed individually to find the best balance between performance, drivability and reliability, then validated on our dyno. Some requests call for fully customised development; this mastery of electronic development, right up to designing our own modules, is today one of the company's main strengths.

Why choose Techtronic

  • Automotive electronics expertise built up since 2009
  • Latest-generation diagnostic and programming equipment
  • Custom-developed maps, never generic ones
  • Every job validated on the dyno, with a report to back it up
  • Cars, vans, HGVs and agricultural machinery under the same roof
  • A single point of contact, from accurate diagnosis to completion
