At MTG AUTO SPORT, we carry out the Flexfuel E85 conversion through a custom engine remap, with no add-on box installed.
Each vehicle is assessed individually to ensure optimal operation on Bioethanol E85 fuel, while guaranteeing engine reliability and safety.
The remap is carried out using professional equipment and a rigorous methodology, tailored to the specific characteristics of each engine.
This work involves precisely modifying the ECU parameters so that E85 fuel can be used under the best conditions of performance and durability.
The modifications cover in particular:
– Fuel injection management
– Cold start optimisation
– Lambda parameter adjustment
– Adaptation of the engine maps
– Checking of engine operating values
– Testing and validation of correct operation after the work
Each conversion is carried out to order, taking into account the condition of the vehicle and how it is used.
The benefits of the Flexfuel E85 conversion:
It offers an economical and high-performance solution for your petrol vehicle.
This conversion notably allows you to:
– Significantly reduce fuel costs
– Improve driving smoothness and enjoyment
– Retain the engine's original performance
– Drive on either E85 or petrol, interchangeably
– Optimise overall engine operation
Compatible vehicles
The Flexfuel E85 conversion is possible on a wide range of petrol vehicles, subject to technical compatibility.
It applies in particular to:
– Petrol vehicles of all makes
– Indirect or direct injection engines
– Naturally aspirated or turbocharged engines
– Recent or older vehicles
Before any work, we systematically carry out a full vehicle compatibility check.
Important information regarding certain ECUs
Some recent vehicles have protected ECUs that require a specific procedure before the engine ECU can be read or written.
Depending on the type of vehicle and ECU fitted, an unlock procedure may be necessary to allow the work to be carried out.
Compatibility and the working method are systematically checked before any operation.
In some cases, a Bench / Boot procedure or a manufacturer-specific procedure may be required.
If an additional unlock operation is necessary, the customer will be informed before any further work or additional invoicing.
Checks and safety
Engine safety and reliability are at the heart of our approach.
That is why every conversion includes:
– A preliminary vehicle diagnostic
– A check of the engine parameters
– A check after remapping
– Validation of correct operation
Important notice (professional)
The vehicle must continue to be used in compliance with the regulations in force.
The E85 flex-fuel conversion must be carried out by a qualified professional with the necessary equipment and skills.
Correct operation is guaranteed provided that:
– the vehicle is serviced regularly
– the manufacturer's recommendations are followed
– there is no prior mechanical fault
