Bentley ECU Remapping & Engine Tuning

We list remaps for five Bentley models and 13 engine variants, all petrol. Petrol remaps typically add +8% to +17% power.

Cars as truly special as Bentley really do deserve the best, as such when we remap the engine ECU on any Bentley we are mindful of the qualities that make this marquee so special. As such we ensure that the ECU remapping we offer on all Bentleys will not detract from the silky smooth power delivery. Our ECU remapping service will iron out the flat spots in the power deliver as well as increasing the peak power output. In fact most of our customers report back and tell us that their Bentley seems to drive even smoother after the ECU remapping!

We appreciate that most Bentley owners would be much happier if their ECU was programmed in situ, as such we have spent a lot of time and money developing a system that lets us remap the ECU via the diagnostic port.

We have developed all our Bentley ECU remaps on our Dynojet 424 XLC² dyno. This dyno has speed linked rollers and as such can run advanced 4WD cars like the Bentley without damaging or overloading their sophisticated differential systems and prevent the cars cars traction control systems reducing power output.
