Why Remap My Vehicle?

As with most modern technology, the cars of today are controlled by internal computer systems referred to as 'Electronic Control Units' or 'ECU'. The program stored within this ECU is known as a 'map' hence the term 're-mapping'. When manufacturers design a vehicle and its engine, they generally have a ‘1 size fits all’ approach to the way the ECU map is programmed. Many variables need to be taken into consideration.

The type of fuel you put in your tank for example, has a big effect on the way the engine runs. It would not be commercially viable for manufacturers to create a separate ECU map for every region, so instead they design the vehicle to be able to run on the lowest grade fuel. Most of Europe and the UK benefit from very high quality fuel so we can optimise the vehicle's ECU map to make the most of this fact.

Manufacturers also need to sell their cars to a range of different drivers. The Mk5 VW Golf for example, leaves the factory with a 2 litre turbo diesel engine producing 140bhp. This car could appeal to both a young person wanting a fast and fun hatchback or an older person looking for an easy to drive, comfortable car. How do they get around this issue? They make a car that’s fast enough for the younger person, but without the sharpness and instant throttle response that the older person may find hard to live with.

PDT can accurately, safely and reliably re-map your vehicles ECU to make the engine perform exactly as you want it to (within safety tolerances of course).
