Diesel Remapping

Diesel tuning is very popular because of how well diesel engines respond to ECU remapping. When it comes to remapping diesel engines, we can offer economy and performance remapping or even a mixture of both.

Our BlueOptimize products are designed specifically for diesel engines, with the benefit of having lower fuel consumption and emissions which in turn will save you money.

But Viezu’s specialism goes further than just economy, with our expert diesel remapping offering a large increase over stock power. Diesel remapping is also very popular for fleet operators, thanks to our remapping software that vastly improves fuel economy.


Our petrol ECU tuning is developed for performance giving you a better throttle response, acceleration and of course increased bhp. The performance can be increased even further with a range of performance parts which Viezu Technologies can supply and fit at our workshop in Warwickshire, just outside of Stratford upon Avon.
