The benefits

In the case of the John Deere 6850 12.5 439HP 439hp engine, our ECU remapping file is tailored for more power and flatter torque, reduced fuel consumption, and an improved throttle response. By optimising the torque curve the John Deere 6850 12.5 439HP engine produces more torque at lower RPM. This also means that you can change gear earlier, so your John Deere engine will run at lower revs and hence more efficiently.

The process

We analyse your tractor 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 John Deere 6850 12.5 439HP engine and its fuel consumption. We can customise the ECU for any tractor.
