Most commonly asked FAQ'S 


What Does Remapping a Car Mean?

Simply put, remapping, sometimes called ECU tuning, is when the settings on a car’s ‘engine control unit’ (ECU) are altered to improve several areas of the vehicle’s performance. By tweaking the settings on this small computer, the owner can customise how the engine works, and ultimately change the output of the vehicle to their own preferences.


How Does Remapping Work?

Remapping a car changes the manufacturer’s default settings and software on the ECU, replacing it with new software which can be tweaked and customised to the owner’s specifications.

When a vehicle is remapped, the old ECU software is overwritten when the customised software is plugged in to the car’s serial port (sometimes referred to as an OBD port tuning), however on some Types of ECU this process has to be carried out by removing the ECU from the vehicle and gaining access to its internal hardware and flashing the EPROM directly (also known as bench tuning). We ALWAYS use a diagnostics tool on your vehicle with a road test to check for fault codes and live data BEFORE and AFTER we carry out a Remap.


What Does ECU Remapping Do?

As mentioned above, remapping allows you to alter the performance of your vehicle by altering how the engine drives the car, however, it’s how the driver chooses to use the tuned car that ultimately decides what effects the ECU tuning will have and how fuel economic it becomes.

Remapping a vehicle will also have an immediate effect on speed and power; in most cases, remapping your ECU will increase horsepower by 30-40bhp, and torque up to 80nm!

A car’s engine will become more responsive, allowing the driver to overtake more easily. This can also cut down on the number of gear changes the driver has to make, allowing them to handle situations that require more torque without dropping down to lower gears. Again, this can help boost fuel economy if used strategically.
