The technical manual always includes a chapter on the software tool. For LPI Vialle, you need:

Parameter table from manual:

| Parameter | Petrol Mode | LPG Mode (Target) | | :--- | :--- | :--- | | LPG Pressure | N/A | 5.5 – 6.5 Bar | | Injector opening time | 2.0 – 3.5ms | 2.2 – 4.0ms | | Lambda correction factor | 0.95 – 1.05 | 0.98 – 1.02 | | Pump PWM duty cycle | 0% | 65% – 85% | lpi+vialle+technical+manual

If your live data deviates by >20% from these manual values, the manual instructs you to perform a "Zero pressure calibration" (disconnect return line and run pump at 10 bar).

The LPI Vialle system is hydraulically complex. The manual provides a color-coded circuit showing: The technical manual always includes a chapter on

One page in the Vialle LPI manual warns: “If engine coolant temperature exceeds 95°C, LPI system will disable liquid injection and revert to vapor start mode.”
Why? Liquid propane in a hot fuel rail can vaporize prematurely — causing vapor lock. Most vapor systems never deal with this. LPI engineers had to solve chemistry and fluid dynamics.

In the world of alternative fuels, few names command as much respect among engineers and converters as Vialle. For decades, the Dutch company was the vanguard of LPG (Liquefied Petroleum Gas) technology, moving the industry away from primitive vaporizers and into the era of liquid injection.

For mechanics, tuners, and automotive students searching for a Vialle technical manual, the search often represents a desire to understand the "Blue Power" legacy—specifically how the company solved the thermodynamic puzzles of injecting liquid gas directly into an engine.

This article explores the technical architecture of Vialle’s LPI systems, the components detailed in their technical manuals, and why this technology remains relevant today.
