⚠️ Liquid propane boils at -42°C (-43.6°F) at atmospheric pressure. If liquid LPG contacts your skin during a component swap (such as removing an injector or disconnecting a fuel line), it causes instant, severe frostbite . Professionals working with LPI and Vialle systems can

The vehicle's original engine computer monitors variables like engine load, ambient temperature, mass airflow, and oxygen levels via the

The wiring harness is critical for seamless integration with the vehicle’s OBD-II and factory engine controls. Installers must tap into the petrol injector ground-control wires to allow the LPE module to read the signal durations. Lpi Vialle Technical Manual

: The phase change from liquid to vapor absorbs heat, increasing intake charge density. The Flush Phase and Start-Up Sequence Blow dry

This requires safely evacuating the LPG tank, removing the multi-valve assembly, draining the old fluid, and refilling it with the exact volume of factory-specified Vialle fluid. Fuel Rail Flushing

Unlike standard vapour injection systems, which rely on an evaporator and mixer, LPi injects LPG directly into the intake manifold in its liquid state.

Located in the engine bay, this component regulates the pressure differential between the fuel rail and the tank. It ensures that a consistent flow of liquid LPG is always available at the injectors and routes excess fuel back to the tank via a return line. The LTC (LPG Treatment Unit) / Coupe Unit
