Back to Stock, also known as factory restoration, consists of reinstalling the original manufacturer file into your vehicle’s ECU. This restores the initial settings in terms of performance, fuel consumption, and legal compliance.
This operation is carried out through ECU reprogramming. We write the original binary file back into your ECU, removing any previous modifications (chiptuning, EGR off, AdBlue off, etc.).
When an ECU is modified with tuning software, an internal key may be written to validate the modification. Returning Back to Stock restores the ECU to its original factory condition, just like when the vehicle left production.
You recover the original ECU mapping, free from any modifications or alterations.
Your vehicle becomes compliant again with emission standards and original certifications.
Any power gains, fuel economy improvements, or fault removals from previous remaps are lost.
A vehicle restored to its stock condition reassures buyers and makes resale easier.
It may be necessary for passing inspections, complying with legislation, selling the vehicle, or simply canceling a tune that no longer suits your needs.
No. After restoring to stock, you can reprogram your ECU again at any time if you wish.
Most cars, vans, trucks, agricultural and industrial machines with reprogrammable ECUs are compatible with Back to Stock restoration.
Restoring your ECU to stock is an important step in the life of a tuned vehicle. Whether for legal, technical, or commercial reasons, reinstalling the factory file puts your ECU back in its original condition. This operation is often required when selling a vehicle, passing a technical inspection, or undoing an unsatisfactory tune. While it means losing performance or fuel economy optimizations, it ensures compliance, reliability, and peace of mind.
