Why should I remap my car’s ECU?

When car manufacturers create engine maps for the ECU, they have to develop them so

that the engines they control have a balance between fuel economy and performance for

all geographical regions and all driving styles.

As a result, the software on your car is not necessarily optimized for your driving style or

for fuel supplied in the country in which you live. Understanding this, many vehicle

owners wish to further refine their car’s engine map through the process known as “ecu

remapping” so more the engine’s performance potential can be released.

Typically non-turbo petrol engine cars have less to gain from remapping than turbo

charged vehicles regardless of whether or not the engine is petrol or diesel. Turbo

diesel engines tend to realize the most gain from ECU remapping as they benefit both

from the turbo as well as from their higher compression ratio. But equally performance

increases will differ because the requirement of the vehicle owner will be different.

Not every car owner wants the most powerful vehicle, some would rather a blend of

improved overtaking performance when required mixed in with improved fuel economy

for the rest of the time.
