Thank you for your enquiry regarding upgrades for your Focus.
We can offer two different types of upgrades for your vehicle.
The first is an ECU remap. Using our equipment and software we download the existing data from the ECU and use this as a base to create our performance ECU remap. Using the existing data ensures that manufacturer information is left in place, making the upgrade very difficult to trace. Once the performance version has been made it is uploaded to the vehicle ECU.
This upgrade will provide an additional 25-30bhp and 50-60nm of torque.
The second type of upgrade is a plug-in module that connects to a sensor on the fuel system and runs in-line with the existing engine management system. The module features manufacturer specification plugs to provide a condition sealed connection and a quick installation. It can be fitted or removed in a short period of time, reverting the vehicle to standard form once removed.
This upgrade will provide an additional 20-25bhp and 40-50nm of torque.
Both upgrades will transform the way the vehicle drives, increasing the power and torque throughout the rev range. The upgrade can also provide a fuel economy saving of 2-4mpg depending on driving style. The additional power and torque allows the driver to move up through the gear box quicker and hold the gears for longer, resulting in more driving time being spent in the lower and more fuel efficient rev range.
The costs of the upgrades are as follows:
ECU Remap: £350 plus VAT
Module: £360 plus VAT
