Multi-Cylinder Fuel Control and Component Selection
This sequential gas conversion configuration is offered for compatible 6-cylinder and 8-cylinder MPI gasoline engines. Select a CNG or LPG system with the appropriate ECU, injector arrangement, reducer and sensors.
The proposed controller is the Mini-2568D-6-8CYL. Confirm the exact hardware, firmware, harness and supported injector configuration before ordering. The selected version must provide the channels and functions required by the engine.

What Components Are Supplied?
The quotation must identify the supplied components and quantities. The proposed package contains the following items, with specifications selected for the intended engine and fuel.
Gas ECU: Controller with the required injector channels and matching firmware.
Injector assemblies: The required number of supported gas injection channels.
Reducer: Fuel-specific unit selected for the operating conditions and engine demand.
Sensors: Compatible pressure and temperature sensing components.
Wiring harness: Harness matched to the controller and installation.
Gas filter: Filter selected for the fuel phase, flow and pressure conditions.
Hoses and fittings: Specified line sizes, connections and quantities.
This component list does not establish a complete vehicle installation package. Confirm the storage cylinder or tank, valves, filling connection, mounting hardware, switch, software and communication cable separately. Read our conversion kit component guide for the role of each system part.
How Are Injectors and the Reducer Selected?
Injector sizing depends on engine demand and defined gas operating conditions. Provide the engine code, displacement, power requirement, intended fuel and regulated pressure before selecting injector flow and nozzle configuration.
Coil resistance must match the ECU driver specification. The 2Ω and 3Ω options cannot be selected by fuel name alone. Confirm the supported injector model, drive requirements and software profile.
CNG and LPG require different fuel-delivery specifications. Select the corresponding reducer, seals, filtration and lines. Browse our gas pressure regulators for related products.
Factory and Processing Image
Calibration and Commissioning
Calibration must match the engine and installed hardware. Confirm the software, communication interface, injector profile, sensor settings and fuel-switching procedure for the selected controller.
Automatic setup, where supported, does not replace operating checks. Follow the controller instructions and verify the required engine conditions during commissioning. See our injector rail and ECU calibration guide for related information.
Frequently Asked Questions
Does this configuration fit every 6-cylinder or 8-cylinder engine?
Compatibility requires more than the cylinder count. Confirm the engine code, gasoline injection type, signal requirements and controller support. This page describes MPI applications and does not establish direct-injection compatibility.
Can one injector rail configuration serve both engine sizes?
The installed system requires the correct number of injection channels. Confirm the rail arrangement, ECU outputs, mounting and hose layout for the specific 6-cylinder or 8-cylinder engine.
Can I use an MP48 controller instead?
The controller must support the required channel count and system functions. The 3- and 4-cylinder MP48 configuration described elsewhere on this site should not be selected for this application without separate documentation establishing support.
Is the same package suitable for both CNG and LPG?
Choose one documented fuel configuration for the installation. Controller fuel support does not make the reducer, tank, valves and other fuel-contact components interchangeable.
Can components be ordered separately?
Individual replacement components can be requested. Provide the existing part identification and specifications so the replacement can be checked against the system.
What are the packaging and warranty terms?
Packaging and warranty must be stated for the quoted configuration. Confirm the number of kits or components per carton, included items, warranty period and claim terms before purchase.
Installation and Maintenance
Installation requires a qualified autogas technician and model-specific instructions. Verify component compatibility, mounting, wiring, gas connections and the applicable functional and leak checks before returning the vehicle to service.
Maintenance must follow the instructions for each component. Replace or service filters at the specified intervals. Clean or dismantle injectors only where the manufacturer provides a service procedure.
