Why map my vehicle?

One of our most frequently asked questions is;
‘Why doesn’t the manufacturer offer this service straight from the factory?’
The answer is, the manufacturer looks at cutting costs across the production line, so they produce a universal ECU to be exported worldwide, to work in all different types of countries and climates, to reduce manufacturing costs. Therefore it is our aim to get the best out of your ECU.
Our power gains and improved fuel economy are achieved by very careful matching of parameters such as boost pressure, fuel delivery rates & pump timing, along with adjustments to maps that electronically limit torque, throttle response and top speed. All this information in your ECU calibration file is carefully optimised to our exacting standards. It is then programmed back into your ECU and the new and improved vehicle is ready to go.
Our aim when recalibrating your vehicle is always to gain the perfect mix of increased power and torque, whilst affording the driver some incredible fuel economy improvements at the same time. Of course we retain all the safety parameters originally programmed into the engine management system as standard, so as to protect your engine and drive train from damage.
