What Is ECU Remapping?
ECU Remap is the method to reprogramming the car's engine to get control unit and override the factory by default settings. Remapping also known for ECU tuning so don't confuse with the both terms. ECU stands for Engine Control Unit (ECU). It is the process in which driver modify the car engine just to improve the throttle response, torque, fuel efficiency and power.
If you're a motorbike owner, car expert or anyone who want boost their vehicle performance, using this tool will really help you. In the United Kingdom (UK), Ireland, Scotland and in many other countries tuning vehicle is common from Gearbox Tuning to Rolling Road Tuning. Driver's want to check how an optimized engine map can Find Your Vehicle Potential.
If you want to adjust the global regulations and feel qualities you need to detune the engine. Make sure to done tuning from professional which help you to save more fuel . It also depends on the remap stage you choose. Vehicle Tuning Stage 1, Stage 2, or Stage 3, and depends on your car part's.

- Choose the remap stage.
- Add the remap cost.
- Enter any additional modification cost.
Once you enter all the details just simply click on the calculate button and see the results. It shows you the power, Torque and MPD before Remap and also after the Remapping.
You also check your vehicle power and torque gain with total investment cost. The tool also find Hours power per Pound (£) and give you note on performance to improve cost.
What Are the Stages of Remapping?
Stage 1 Remap which is good for stock vehicles. This is gained with 20% to 30% power and torque. Also improve your fuel economy if you the vehicle everyday.
Stage 2 Remap need some mods like intercoolers and exhaust system which give you a 25% to 35% performance as compare to stock. If you want more better performance it is best option for you.

For style performance setups who want the simulation tuning. Our calculator supports a wide variety of tuning types, including Eco Blue Tuning, which targets efficiency in diesel vehicles without sacrificing torque.
The Role of Dyno & Rolling Road Tuning
