ECU Remapping (Flash Tune)

Optimises your engine control unit’s outputs. Most manufacturers set their ECU’s conservatively. Remapping or ‘flash tuning’ your ECU fine tunes the software that controls engine performance.

Efficiency is greatly improved – and because it’s the same process the manufacturer uses – it’s safe for your engine.

When Should I Consider Flash Tuning?
When aftermarket changes are made to your vehicle, such as the addition of a turbocharger or intercooler, conversion to an alternative fuel, or changing of the exhaust system. If your vehicle is exhibiting noticeable acceleration lag or flat spot. ECU remapping virtually eliminates this. Or – when you regularly tow with your vehicle, want to reduce fuel consumption and boost power.
