Chiptuning for 431

Puretuning is a specialist in Chiptuning petrol and diesel engines for performance and fuel efficiency. We have years of experience remapping Challenger agricultural engines to optimise for performance and efficiency.

Many Chiptuning companies around the world choose Puretuning for tuning their Challenger engines. Our Challenger 680B 12.5 431HP engine remapping file provides the best possible performance and results within the original safety margins.

The benefits

In the case of the Challenger 680B 12.5 431HP 431hp 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 Challenger 680B 12.5 431HP engine produces more torque at lower RPM. This also means that you can change gear earlier, so your Challenger 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 Challenger 680B 12.5 431HP engine and its fuel consumption. We can customise the ECU for any tractor.
