Is your engine running smoothly? We provide expert engine tuning and engine diagnostics in the Arundel, Bognor Regis, Chichester area at our Fontwell garage. For many people a tuned car is simply one which runs at peak efficiency. This is achieved by a full service and adjustment to factory specifications.

For others the aim is to get their vehicle running and performing better than originally intended. Due to the conservative settings used by manufacturers and low cost manufacturing methods, there are lots of methods for improving your engine’s performance.

These methods can also be used to maximise economy by pushing the engine into its most efficient range. The Crypton tuning machine is used to run a diagnostic check on older vehicles to show up faults.

There are many settings which effect how your engine runs. With engine tuning we can make adjustments to ensure that you machine is running efficiently. Engine tuning can also increase performance beyond the manufacturers standard settings.

The ECU is the Engine Control System. Most modern engines have an ECU. It is a mini computer that can control many aspects of how your engine performs under different conditions. If it goes wrong you need a garage with specialist equipment to reset it.

Engine mapping is a series of settings controlled by the vehicle’s ECU. The Engine Control Unit can be remapped to give better performance. Often manufacturers set them to accommodate all kinds of driving conditions and fuels. For example UK fuel standards are high and the settings can be altered to specifically suit this higher grade of fuel.

Most definitely. The more efficiently your engine performs the less energy it needs to carry out its tasks. It is also environmentally healthy because a well tuned engine not only uses less fuel but it puts out fewer emissions. A well running engine will also last longer. The engine parts perform better and replacement times can be extended.
