New BMW, Mini and Toyota ECUs Now Compatible with Chiptuning at RStronic

At RStronic, we continuously update our chiptuning protocols to stay aligned with the latest technologies introduced by car manufacturers.

Until now, BMW, Mini and Toyota models produced after 2020 were equipped with locked engine control units (ECUs), making any form of optimization impossible without a complex and costly procedure.

The only known solution came from Femto, based in Finland — a reliable service, but one that was long, expensive, and required shipping the ECU abroad.

Today, a new technology developed by Autotuner completely changes the landscape.

It enables ECU unlocking directly in Europe, with shorter turnaround times and a significantly lower cost.

A breakthrough that finally makes chiptuning accessible and affordable for a wide range of modern BMW, Mini and Toyota vehicles.

Major Cost Reduction Compared to the Femto Solution

Previously, unlocking these ECUs required shipping them all the way to Finland, leading to long vehicle downtime and high transportation costs.

With the Autotuner solution, the process is now handled within Europe through a controlled and certified network.

In practical terms, the total cost is now around €500 (VAT incl.) more than a standard RStronic Stage 1 chiptuning,

compared to a much higher extra cost with the old Femto method.

The result: a faster, simpler and far more affordable operation.Calculateurs et modèles concernés
