Econospeed is a dynamic throttle controller that allows a vehicle's maximum road speed, engine speed, and maximum rate of acceleration to be limited by any customer defined criteria.

By electronically restricting the vehicles maximum rate of acceleration and forcing earlier gear changes by limiting maximum revs Econospeed encourages economical and careful driving. It is a fit and forget system with no training or management required.
It simply means that over-revving a vehicle will not be possible but full power will still be available.

EconoSpeed is connected between the accelerator pedal and the Engine Control Unit (ECU). It constantly monitors acceleration demand from the driver, with the throttle pedal, as well as monitoring the engine and road speed of the vehicle via a Controller Area Network (CAN).


When acceleration is at an optimum level, EconoSpeed allows output to the ECU, as much throttle as the driver requests. However, if EconoSpeed detects that acceleration demand is (or is about to become) too high, it restricts acceleration to a pre-determined level. This level is based on the speed the vehicle is travelling at the time.
