All vehicle remapping is a re-flash service. This requires us to upload a new file to your ECU. The process takes on average 1-2 Hours.

Furthermore Remapping is done with specialised tuning software on a computer which connects to the car’s ECU. 

During the remapping process, various parameters of the engine’s operation such as fuel injection, ignition timing, and turbo boost are adjusted to enhance performance. The remap file is customised to suit the specific make and model of the car, as well as any performance upgrades installed.

After writing the new software to the ECU, the car undergoes a test using road or a dyno test to ensure the effectiveness and safety of the new settings. Sometimes, additional adjustments may need to be made to optimise the performance of the car/vehicle.

Increased Power Capabilities 

One of the most common changes of ECU remapping is increasing the power capabilities of the engine, resulting in quicker acceleration and faster top speeds due to a noticeable increase in output. 

Improved Responsiveness & Fuel Efficiency

But ECU remapping isn’t just about speed and power; it can also improve the responsiveness of your car and its fuel efficiency by allowing you to reduce the number of gear changes required to overtake and perform other driving situations which require torque and horsepower, but it does require you to perform these correctly.

Yes, it’s safe to do as long as it’s done correctly by a trained professional.
