LSTAG 400 DPI is a modern sequential gas injection controller, which allows gas supply to selected models of cars with direct injection.
The STAG 400 DPI system controller constantly performs gasoline injection to protect petrol injectors from damage, which in engines with direct petrol injection cannot be permanently switched off. Their tips are located in the combustion chambers and the gasoline flowing through them cools, lubricates and cleans them.

In direct injection systems, gasoline injection serves to protect the gasoline injector. Gasoline injection in such an engine is constant and continuous.
The percentage of gasoline injection and also individual gasoline consumption depends on the type and class of the system, as well as the type of engine.

Direct injection autogas systems are dedicated to a specific engine code. Due to the need to emulate gasoline injectors and the high-pressure pump, the STAG 400 DPI controller must be fine-tuned to the gasoline controller. We are constantly working on the development of the controller and the development of new codes. You can take part in the research by participating in the Extended PLUS program.
