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 (within legal limitations).
When a vehicle is remapped, the old ECU software is overwritten when the customised software is plugged into the car’s serial port (sometimes referred to as an OBD port). This simple functionality has made the process of tuning a vehicle considerably easier.
We also offer ECU out or bench tuning alongside box tuning or rail tuning. These can be purchased from us and sent to you already tuned to your desired settings and simply plugged in instantly mapping your car and controlled from your phone!!
What does ECU Remapping do?
Remapping, sometimes called ECU tuning, is when the settings of a car’s ‘engine control unit’ (ECU) is altered to improve several areas of the vehicle’s performance. By overwriting the existing settings with new software, the owner can re-programme the car to manage the fuel injection, airflow, sensors and more (within legal limitations).
What is Remapping?
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.
For example, it’s a common belief that remapping a vehicle has no effect on fuel economy, however, this technically isn’t true. As a result of ECU remapping, a car usually sees an increase in power, which can come at the expense of higher fuel consumption. Owners will often drive their cars more ‘enthusiastically’ after remapping, accelerating quicker when possible to enjoy the noticeable difference in output their car has, and therefore, further increasing fuel usage.
On the other hand, if the driver chooses to change their driving habits to make the most of the increased power and torque throughout the ‘rev range’ and gear changes, then fuel economy can be improved. It really comes down to how the driver chooses to use the tuned car which decides how economic it becomes.
Remapping a vehicle can also have an immediate effect on speed and power; in some cases, remappers claim to have increased horsepower by 30-40bhp, and torque up to 80nm! A car’s engine can also 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.
KESS or KTAG
Kess allows you to read and write the ECUs of cars, bikes, trucks, tractors and boats simply connecting the tool to the diagnostic port. An easy and simple way to apply the mapping to your vehicle.
KTag is used to read and write the ECU while on the bench: Each of the microprocessor, EEPROM, and flash memory can be accessed by connecting the tool to the ECU board. Using KTag means that potentially the vehicles ECU needs to be removed to apply the map and this process takes longer.
Depending on the make, model and age of the car will dictate which method is used to map your vehicle.
