ECU Software & Calibration

Also known as ECU Remapping, Tuning, or Calibration to enhance vehicle performance & driveability. At Jaye Cars , we develop in-house software to increase performance on a variety of vehicles. Our software is developed and tested to ensure that reliability is not affected. ECU software calibration includes an increase in the engine’s horsepower, torque, faster throttle response and power throughout the RPM range. One of the positive side effects of an ECU calibration is the increase in fuel economy.

ECU Remapping

An ECU is a small computer that controls the operation of an engine. Car manufacturers make the engine smoothly run by calibrating the ECU software. These settings are made before vehicles launch to the market.
There are a lots of variables which must be considered in the ECU software setting such as different weather conditions, rules and restrictions and fuel quality and other parameters which you can modify all these settings by ECU Remapping. Remapping can adapt the car to the climatic conditions of the region and also the fuel quality of different countries. After ECU remapping, fuel consumption will be fully optimized and reduced. Moreover, the car’s acceleration will be better and also engine knock will be eliminated.

Is Remapping Safe?

Yes — when carried out professionally, remapping is safe for your vehicle. We use proven tuning files designed specifically for your make and model. Every remap stays within the safe limits of your engine and gearbox.

Gearbox Map Adjustment

Our gearbox adjustments are available for a selection of vehicles. We can control gearbox parameters like gearshift change times, clamping force on clutches, and changes to torque limiters. This is more suited to vehicles with a Stage 2 tune or above. We recommend this option to our customers wishing to achieve the most from their vehicle’s performance.
