Remapping provides many benefits for the longevity of your vehicle

ECU remapping involves updating and modifying a vehicle's engine control unit to help the vehicle perform at its best. The ECU acts as the "brain" of the car, gathering information from sensors and sending out the necessary information to the injection system.

improved throttle response

ECU remapping optimizes engine control, reducing lag and making your car more responsive

increased fuel economy

Calibrating the parameters can result in a reduced fuel consumption and optimize efficiency

up to 20% more power

Get up to 20% more power and improve your vehicles performance by optimizing your ECU


Increasing your vehicle's power can improve efficiency and save money over time. This is essential for business

Let us know what you want

your goals

Tell us your goals: Maybe you want better performance when towing, or maybe you are looking for more torque from your tractor. Whatever you are trying to accomplish, let us know. We will figure those goals into our remap customization. There is not a one-size-fits-all approach to engine remapping. Depending on what you’re trying to accomplish in terms of performance improvements, there might be different configurations to get you there. As such, it is vital that you know what your goals are and convey them clearly to your technician.​

An engine control unit (ECU) is a type of unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by taking input from various sensors and computes the information using a preprogrammed ‘map’. The ECU will take the inputted information and compute the required output, such as quantity of fuel to inject. 

When we remap a vehicle, we aim to optimise power and torque output of the engine within the safety margins of the manufacturer. We will never come close to reaching the limits of a vehicles engine, we guarantee it. 

Each individual person uses their vehicle differently and has different needs and requirements, we always take these factors into account when remapping any vehicle to match a vehicles performance to the owners specific set of needs. 

There is a number of benefits including increased performance, torque, throttle response and fuel economy!

One of the main benefits to ECU remapping is moving the power and torque further down in the RPM range meaning you access more power and torque earlier and with less throttle. Typically, we see improvements of 10-15% in horsepower and torque. Depending on the vehicle this can be slightly lower or higher. 

Another benefit that is commonly seen from ECU remapping is the elimination of any flat spots in the power and torque curve. It is common for modern vehicles, particularly common rail diesels to have a flat spot off idle which is demonstrated in the dyno read out below, the bottom line is the power and torque curves of the pre-run when the vehicle was delivered to us and the top line is after ECU remap.


We can re-map the majority of diesel vehicles and equipment including Trucks, Buses, Tractors, Agricultural and Marine applications. Not all cars can be remapped, usually due to their age. Typically, cars produced before 2000 are too old and don’t feature the car remapping software needed to optimize the vehicle’s performance.
