ECU Coding and Programming

An Electronic Control Unit (ECU) is an electronic unit that controls one or more of the electrical systems or subsystems in a vehicle.

In-car software is becoming one of the leading needs for service and updating software may be the only way to fix some of these issues: drivability, fuel efficiency, power loss, fault codes, and durability of mechanical parts.

ECU configuration also allows users to personalise settings in their vehicle such as the chimes on their car, set how many times its one-touch signal flickers, remember settings for Start/Stop systems, and more. Some vehicles allow you to activate or deactivate certain functions.

What is an ECU, and why does it need Programming?

An Electronic Control Unit (ECU) is an electronic unit that controls one or more of the electrical systems or subsystems in a vehicle.

Computers and software in cars have been expanding at an exponential rate. In-car software is becoming one of the leading needs for service and updating software may be the only way to fix some of these issues: drivability, fuel efficiency, power loss, fault codes, and durability of mechanical parts.

Mobile Automotive Diagnostics and Programming involves changing certain software configurations and parameters to allow and enhance functions in your vehicle. Local regulations can affect what comes with your car fresh out of a dealer, but with these modifications, you can customise your car to your specific needs and requirements.

Why Reprogram the Original ECU?

Most vehicles are tuned with the average user in mind, with no vehicle modifications and with the highest emissions restrictions applied.

Reprogramming the original ECU is the cleanest, safest and quickest way of correctly compensating for engine, induction and exhaust modifications. The maps in the standard ECU may be adjusted to cater for virtually any modifications that are likely to be made to a car.

The safety features of the ECU are retained, such as sensor checks, fuel cut, boost cut, rev limit, speed limit and ‘limp home’ mode, though they may be altered to suit the car and its modifications. E.g. if the ECU detects a problem (engine over-temperature or failed sensor), it is still in full control of boost pressure and is able to take evasive action to preserve the engine. This is in stark contrast to external controllers and piggy back modules that either take over control of engine functions, or fool the ECU about the state of its sensors.

Customise Car Feature Settings

ECU configuration also allows users to personalise settings in their vehicle such as the chimes on their car, set how many times its one-touch signal flickers, remember settings for Start/Stop systems, and more. Some vehicles allow you to activate or deactivate certain functions.
