The benefits

In the case of the Mercedes-Benz A 45 MG S 421hp engine, our ECU remapping file is tailored for more power and torque, reduced fuel consumption, smoother acceleration and improved throttle response. By optimising the torque curve the Mercedes-Benz A 45 MG S 421hp engine produces more torque at lower RPM. This also means that you can change gear earlier, so your Mercedes-Benz engine will run at lower revs and therefore more efficiently.

The process

We analyse your vehicle and can adjust the engine management programme, also known as the ECU (Engine Control Unit). This engine software is largely responsible for the behaviour of the Mercedes-Benz A 45 MG S 421hp engine and its fuel consumption. We can customise the ECU for any car, van, truck or tractor.
