Fuel Configuration, Engine Matching and Kit Contents
This sequential gas injection kit is offered for compatible PFI/MPI gasoline engines. Configurations are available for 3-, 4-, 6- and 8-cylinder applications, using the appropriate controller, injectors and fuel-delivery components.
Select either an LPG or a CNG configuration for the installation. The fuel choice determines the required reducer, storage equipment, valves and lines. Shared electronic control functions do not make the fuel-contact components interchangeable.

What Does Each Main Component Do?
Gas ECU: Processes supported engine and sensor inputs to command the gas injectors.
Injector rail: Meters gaseous fuel through channels matched to the engine and ECU driver requirements.
Reducer: Provides the fuel-pressure regulation required by the selected system. LPG vaporization and any heat-supply requirements depend on the specific design.
Wiring harness: Connects the controller to the supported signals and components according to the wiring diagram.
MAP sensor: Provides manifold absolute pressure information where required by the controller configuration.
The complete supply scope must be itemized. Confirm whether the storage cylinder or tank, filling connection, shutoff devices, mounting hardware, software and communication cable are included or separately supplied. Read our conversion kit component guide for related selection information.
How Do You Select the Correct Configuration?
Engine injection type and cylinder count are the starting points for selection. Provide the engine code and required fuel before choosing the ECU, injector arrangement and reducer.
Engine: Vehicle model, engine code, displacement, cylinder count and power requirement.
Injection system: Confirm PFI/MPI operation and the supported vehicle signals.
Controller: Match injector channels, firmware, sensors and calibration software.
Injectors: Match electrical drive requirements, flow characteristics and operating pressure.
Reducer: Match the fuel, inlet conditions, delivery capacity and required outlet behavior.
Installation: Check available space, mounting, connections and destination-market requirements.
Direct-injection engines require a separately supported solution. This PFI/MPI application does not establish GDI compatibility. Review our direct-injection conversion guide when identifying the engine type.

Calibration and Optional Controller Functions
Calibration must match the selected hardware and engine. Confirm injector profiles, sensor settings, reducer conditions and the fuel-switching procedure using the supplied controller instructions.
OBD communication and automatic adaptation are version-specific functions. If required, request the exact ECU model, supported protocols and documented function list before ordering.
Automatic fuel switching depends on the controller settings and system design. Confirm the required temperature, pressure and other switching conditions. A single fixed threshold should not be applied to every installation.
Frequently Asked Questions
Can the same physical kit serve every cylinder configuration?
Each engine requires the appropriate controller channels and injector arrangement. Confirm the itemized configuration for the intended 3-, 4-, 6- or 8-cylinder application.
Are LPG and CNG components interchangeable?
Fuel-contact components must be selected for the intended fuel and service conditions. Storage equipment, reducers, valves and lines can have different requirements. See our CNG and LPG conversion comparison for related information.
How much can the conversion reduce running costs?
Cost savings depend on local fuel prices and measured fuel consumption. Include any retained gasoline use, maintenance and conversion cost when comparing the operating cost per distance traveled.
Will the kit preserve the original engine power?
Performance must be assessed on the installed vehicle. Fuel properties, engine condition, component sizing and calibration affect the result. Confirm performance through the applicable commissioning and operating checks.
What maintenance interval should be followed?
Use the intervals specified for the supplied components and operating conditions. Follow the filter replacement schedule and inspect gas lines, connections, wiring and any coolant circuit according to the system instructions.
Documentation, Installation and Inspection
Technical claims should correspond to the supplied models. Request datasheets, wiring diagrams, installation instructions and applicable approval or inspection records for the selected components.
Installation requires a qualified autogas technician. Verify component compatibility, mounting, routing, electrical connections and the specified functional and leak checks before completing calibration.
Inspection requirements differ by component. Electrical, pressure, leakage and environmental test records should identify the relevant part, test conditions and acceptance criteria.
