Flex fuel
E85 conversion in Tours - Ethanol and FlexFuel reprogramming at Shiftech Tours
Drive on E85 in Indre-et-Loire with Shiftech Tours
Based in Saint-Cyr-sur-Loire, just outside Tours, the Shiftech Tours center specializes in E85 conversion, engine reprogramming and map optimization. Our FlexFuel calibrations enable your petrol vehicle to run on E85 bioethanol, SP95, SP98 or a mixture of the two fuels, without compromising on reliability or driving pleasure.
Tours and the wider Indre-et-Loire region have a good network of E85 filling stations, in Tours, Joué-lès-Tours, Chambray-lès-Tours, Saint-Avertin, Fondettes, La Riche, Montlouis-sur-Loire and Amboise. Converting to E85 is therefore a coherent local solution for drivers who want to reduce their fuel budget while keeping their engine running smoothly.

FlexFuel reprogramming: an optimised, sustainable solution
At Shiftech, we prefer customised FlexFuel reprogramming, carried out directly in the original engine ECU. This method involves fine-tuning the engine management parameters - injection, ignition, richness - to ensure perfect compatibility with bioethanol while preserving mechanical reliability. Unlike an additional box that applies generic corrections, this approach enables fine, lasting adaptation of engine operation.
Thanks to this calibration, your vehicle can run on E85, petrol or a mixture of the two, without any intervention on your part. Cold starts are optimised, combustion is controlled and overall operation remains within the manufacturer's tolerances. All our calibrations are developed on a power bench to guarantee stable, measurable results that are perfectly adapted to your engine.
Case vs reprogramming
Ethanol box or E85 reprogramming: what's the difference?
An ethanol box enables rapid conversion, but remains a generic solution. It simply makes rough adjustments to certain signals without any real internal calibration work. This approach can lead to irregularities in operation, less controlled combustion, the appearance of warning lights and premature wear of certain components.
in contrast, E85 Shiftech reprogramming is based on in-depth work carried out directly in the original ECU. Every engine parameter - injection, ignition, fuel corrections, cold enrichment - is precisely adjusted, then checked on a power bench. The result is clean combustion, smooth running and preserved reliability.
To give you a clearer idea of the differences, here's a table comparing the two solutions:
| Criteria | Ethanol box | Shiftech E85 reprogramming |
|---|---|---|
| Accuracy of settings | Low, generic correction | Very high, full internal adjustments |
| Engine compatibility | Varies according to model | Optimised for each individual vehicle |
| Cold starts | Sometimes irregular | Perfected management for reliable starting |
| Risk of warning lights | Possible | Very low thanks to calibrated settings |
| Performance | Little changed | Preserved performance and smooth operation |
| Mechanical durability | Average, depending on compatibility | Excellent thanks to controlled combustion |
| Fuel flexibility | E85 + SP, but management is sometimes approximate | Perfectly controlled use of E85, SP or blends |
In short, Shiftech E85 reprogramming is the most reliable, precise and durable solution for a successful bioethanol conversion, perfectly adapted to your engine and tested under controlled conditions.
Technology
Recognised expertise in Tours and the Centre-Val de Loire region
Since 2008, Shiftech has been a European benchmark in engine optimisation. The Tours centre applies this expertise to drivers inIndre-et-Loire and the wider Centre-Val de Loire region, who are looking for a reliable solution for driving on E85 without damaging the performance of their engine.
We support drivers in Tours as well as in Saint-Cyr-sur-Loire, Joué-lès-Tours, Chambray-lès-Tours, Saint-Avertin, La Riche, Fondettes, Ballan-Miré montlouis-sur-Loire, Amboise, Loches and Chinon, who want to make a serious E85 conversion with a calibration that's really right for their vehicle.
Why convert to E85 in Tours?
Your E85 reprogramming at Shiftech Tours: the steps
1Diagnostics and reading the engine map: checking the condition of the vehicle.
2Development of E85 calibration on a power bench.
3Road tests and validation of parameters.
4Return of the vehicle and technical explanations.
The service begins with a complete diagnosis of the vehicle and a reading of the original engine mapping. We then develop an adapted FlexFuel map on the test bench, taking into account the engine's actual behaviour. After this calibration phase, additional checks are carried out to ensure that the readings are consistent and that the engine is running smoothly. The vehicle is then returned with clear explanations of the conversion carried out and how E85 fuel is used on a daily basis.

FAQ - E85 conversion in Tours
Is my petrol vehicle compatible with E85?
Most fuel-injected petrol 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.
