Engine Control Unit is the computer of any vehicle that controls the functionality of an engine. It analyses the information such as the engine temperature, accelerator pedal angle, oxygen content in the burnt exhaust gases, and other parameters. With all this information, the engine adds the right quantity of fuel to provide a good mix of fuel economy, performance, and emission control when pulling away, overtaking, pottering down the road.


ECU remapping changes the default settings and software made by the manufacturer of a vehicle. While remapping a vehicle, the old ECU software is overwritten with the customized software and is put into the car’s serial port. This simple functionality has made the process of tuning a car easier. What ECU remapping does is that it takes data from the ECU’s processing chips of the vehicles and adjusting various parameters within the stock map like fuel pressure, boost pressure ignition advance, and throttle pedal control amongst others to release the actual performance from the engine. Today, no doubt, remapping the car has become a trend for every car lovers so, why don’t you try for yours.


After Remapping from us you will feel the moderate difference in Power, Torque and Fuel economy. The throttle response will be much better and sharper.
After ECU remapping you will get

  1. It helps in increasing the power and torque output.
  2. An increment in the mpg, and finally, an improvement in fuel economy.
  3. Improved vehicle performance and drivability.
  4. A subsequent increase in the efficiency of your vehicle.
  5. Smoother power delivery
  6. The complete customization is possible for your driving needs.
