E85 conversion in Toulouse - Ethanol and FlexFuel reprogramming
and FlexFuel at Shiftech Muret
Drive on E85 in Haute-Garonne with Shiftech Toulouse
Located in Muret, south of Toulouse, the Shiftech Toulouse centre specialises in E85 conversion and engine reprogramming. Our experts will help you transform your petrol vehicle so that it can run on E85 bioethanol, petrol or a mixture of the two fuels, without compromising on performance.
Bioethanol E85 is now one of the most economical fuels available in France. With a dense network of E85 stations around Toulouse and Colomiers, it is a safe, reliable and environmentally-friendly alternative.

FlexFuel reprogramming: the most effective solution
At Shiftech, we prefer made-to-measure FlexFuel reprogramming to the installation of additional boxes. This method consists of adapting the engine management parameters directly in the original ECU, allowing perfect compatibility with bioethanol while preserving mechanical reliability.
- Use of E85, petrol or a mixture of the two fuels.
- Optimised cold starts.
- Engine management compliant with manufacturer tolerances.
- Calibration developed on a power bench for measurable, reliable results.
Each reprogramming is unique, adapted to your engine and tested in our facilities to Shiftech standards.

Case vs reprogramming
Ethanol box or E85 reprogramming: what should you choose?
An ethanol box acts as an additional module between the ECU and the injectors. It enables rapid conversion, but remains generic and does not take account of the specific features of each engine.
Shiftech E85 reprogramming, on the other hand, is based on precise development of the engine mapping: each parameter is adjusted, analysed and tested. The result is optimum performance, with no engine warning lights, fine management of the air/fuel mixture and controlled combustion.
It's the cleanest, most sustainable and most efficient solution for your vehicle.

FAQ - E85 conversion in Toulouse
Is my petrol vehicle compatible with E85?
Most fuel-injected engines can be converted. We always carry out a diagnostic before any work is carried out.
Is E85 reprogramming reversible?
Yes, we can restore your original mapping at any time.
Is an E85 box as effective as reprogramming?
No. Universal boxes do not take account of engine specificities. Shiftech reprogramming guarantees precise, long-lasting tuning.
Does bioethanol damage the engine?
No, when used correctly and managed with the right calibration, E85 poses no risk to the engine.
