An engine control unit (ECU), or engine control module (ECM), is an electronic control unit which controls various aspects of an internal combustion engine's operation. The simplest ECUs control only the quantity of fuel injected into each cylinder or the spark timing of an engine. More advanced ECUs found on most modern cars also control the ignition timing, variable valve timing (VVT), the level of boost maintained by the turbocharger (in turbocharged cars), and other peripherals.
The Prins VSI system has it's own dedicated ECU which interfaces with the vehicles ECU to precisely control the LPG delivery.
