Chiptuning for Jaguar XJ 4.2 V8 SC 400hp

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

Many Chiptuning companies around the world choose Puretuning for their Jaguar ECU remapping files. Our Jaguar XJ 4.2 V8 SC 400hp engine remapping file provides the best possible performance and results within the original safety margins.

The benefits

In the case of the Jaguar XJ 4.2 V8 SC 400hp 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 Jaguar XJ 4.2 V8 SC 400hp engine produces more torque at lower RPM. This also means that you can change gear earlier, so your Jaguar 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 Jaguar XJ 4.2 V8 SC 400hp engine and its fuel consumption. We can customise the ECU for any car, van, truck or tractor.
