ECU Remapping

Let Your Engine Work The Way it Should With an ECU Remap

When your car’s manufacturer was programming or ‘mapping’ its engine control unit (ECU), they had to allow for a wide range of possible operating conditions. So, they compromised.

For example, they had to consider sub-standard fuels, extreme temperatures, high altitudes, different emission laws and the possibility of scheduled servicing not happening.

Remapping Process

ECU remapping means changing various parameters in the program or ‘map’. It frees your engine of the restrictions of ‘average’ ECU settings.

Every engine has a unique map that we can fine tune to improve power output and, in many cases, fuel consumption.

When remapping a vehicle, we take a reading from the ECU’s processing chip of your vehicle and then adjust various parameters such as:

  • Fuel pressure,
  • Boost pressure (on turbocharged applications),
  • Ignition advance, and
  • Throttle pedal control.

What Happens When a Vehicle is Remapped?

When we remap a vehicle, especially when fuel saving is the priority, we focus on improving low-end torque and widening the power band as much as possible. More low-end torque means you need less throttle to maintain cruising speeds when fully laden or going uphill. It also means staying in higher gears at slower speeds and changing gears less often.

How Safe is the Process?

Remapping an engine is a completely safe process. It gives the engine the performance it should have had before compromises were made to the original programming. Every engine will have its own unique map. By adjusting this we can fine tune the characteristics of your engine; unleash more power and in many cases, reduce fuel consumption too.

Does an ECU Remap Improve Fuel Economy?

When you adjust your driving style to take advantage of the extra low-end torque, you will see a decrease in fuel consumption. This is most noticeable on turbo-diesel engines, where we see improvements of up to 20 per cent.
