Lpi Vialle Technical Manual Top [work] Jun 2026

The LPE-7 is the technological core of the LPi system. It is an intelligent slave computer that intercepts the injector signals from your car's original Engine Control Unit (ECU). Instead of using its own fuel map, it translates the petrol injector's timing signal into a precise command for the LPG injector. This approach gives LPi its significant advantages by avoiding performance losses from air displacement, which can be up to 7% in vapor systems, and ensuring the original engine management's self-learning capabilities are fully retained for optimal fueling under all conditions.

The LPI Vialle system requires careful handling and operation to ensure safe performance. The following safety precautions and warnings should be observed:

The term "Top" in the context of Vialle documentation refers to the . Unlike the quick-start guides or owner's brochures, the Technical Manual Top is designed for advanced technicians. It contains: The LPE-7 is the technological core of the LPi system

The LPi system operates as a "master-slave" configuration where the original vehicle ECU continues to manage the engine, while the Vialle LPE unit translates petrol signals into LPG injection pulses.

Extracting the pump module requires emptying the tank entirely using an approved LPG recovery station. Once removed, inspect the internal fluid window. If fluid is discolored or low, the pump requires a formal bench overhaul or replacement. 3. Injector Cleaning Profile (As Needed)
