Services Overview

Aftermarket ECU and software upgrades are a popular performance upgrade choice for higher engine output and engine upgrades. We get a lot of questions from our customers about what the best aftermarket ECU is. Our team has explained for you what to consider when choosing your ECU upgrade.

Aftermarket upgrades

The feeling of building a project or track car is great on its own. However, it gets even better when thinking about all the potential aftermarket performance upgrades.

There are so many possibilities including:

Electronic fuel injection upgrades
Suspension upgrades
Brake upgrades
Intake system upgrades
Exhaust upgrades
Forced induction
Custom wiring and sensor upgrades

One key component if you have done some of the upgrades above already is to upgrade your Engine Control Unit to increase your vehicle’s performance and to make adjustments to suit modifications.

ECU upgrades

The ECU, sometimes also called engine management system (EMS) or engine control module (ECM), monitors and controls the operation and performance of your engine. It is a small electronic box that manages sensor inputs, auxiliary outputs, fuel injection, and ignition of your engine. To do so, the ECU calculates the correct input amounts relying on its digitally stored equations and numeric tables that can be completely customised.

Several variables such as the temperature of engine and fuel, the fuel quality and pressure, the engine demand, and air pressure can influence the mixture ratio the ECU has to determine.

If one variable changes, the ECU calculates the change for other components to maintain the engine efficiency. The ECU keeps track of the inputs, processes these, creates the output in form of engine action and stores the data.

These functions allow the ECU to also pick up on faults in the engine system. If a sensor malfunctions or performs outside of its tolerance range for a period of time, the ECU registers this. It creates and stores a fault code in the system.

This fault code can then be evaluated by our ProSpark team when accessing the fault codes from the ECU memory. Usually, fault codes consist of 5 digits and begin with a letter followed by four numbers.

Vehicle upgrades & ECU

If you have added upgrades to your vehicle, one option is to custom reprogram your stock ECU. This is to inform the ECU of all modifications that have been added. You can therefore then reprogram it with a more optimised data table to match these upgrades. There are several Factory ECU software programs that can allow your stock ECU to become completely tuneable.

In general, most factory ECUs only allow a small amount or no alterations to the original settings at all. Many aftermarket features such as fitting a turbo or cams won’t be supported by those ECUs either. To control your added features and optimise your engine’s performance, you will require an aftermarket ECU.

Aftermarket ECUs allow us to use to full potential of your engine and your other added features so that you can make the most of your vehicle.

Usually, aftermarket ECUs give you the possibility to:

Adjust fueling
Adjust ignition timing
Increase engine reliability
Add new features such as launch and traction control and safety features
Make other adjustments

Custom Wiring Solutions

Reliable and tidy engine wiring is something that often is overlooked. A tidy and well-planned engine harness is key component to any project.

We can create any custom wiring harness to suit your application. Our team works with all types of aftermarket and factory ECU. We can assist with anything from small sensor additions to full engine and vehicle re-wires and Motorsport Harnesses.

We only use the highest quality wiring, connectors, and processes. Our ProSpark team works with you to make sure we can create the best result for your pride and joy, race car or project.
