Two-stroke engines
Review the intake arrangement, crankcase or reed-valve layout where applicable, lubrication requirements and the existing ignition system. These details affect how an EFI conversion is integrated.
ELECTRONIC FUEL INJECTION
EFI begins with
the whole system.
Fuel injection brings electronic control to fuel delivery. A successful retrofit also depends on the mechanical installation, fuel circuit, electrical supply and engine calibration.
Discuss your engineSYSTEM ARCHITECTURE
What an EFI installation brings together.
| Integration area | What to establish |
|---|---|
| ECU and sensors | The control unit uses available engine and operating data to determine fuel delivery. Confirm sensor types, signal requirements and the supported control functions for the selected ECU. |
| Throttle body and injector | The intake interface, air passage and injector arrangement must match the engine and installation. Check geometry and clearance before selecting hardware. |
| Fuel circuit | Define the pump, pressure regulation, filter and plumbing as a complete circuit. Required pressure and flow depend on the chosen injector and engine configuration. |
| Electrical installation | Review supply voltage, power demand, grounding, connectors, routing and protection for the complete system. |
| Calibration and validation | An initial calibration is a starting point. Evaluate the engine across the intended operating range before accepting the installation. |
ENGINE ARCHITECTURE
Two-stroke and four-stroke integration.
Four-stroke engines
Review the inlet manifold, throttle arrangement, timing signals and operating range. The mechanical adaptation and calibration should be assessed for the specific engine.
COMMON QUESTIONS
Before choosing a configuration.
Will an EFI conversion automatically increase power?
Performance depends on the engine, hardware, calibration and operating conditions. Establish measurable targets and validate them on the actual installation; a generic power increase should not be treated as a guarantee.
Can I keep my existing engine?
A retrofit starts with your existing engine. Send its make, model and displacement so that the configuration and any adaptation work can be discussed.
Is an adaptation already available for my engine?
Availability is engine-specific. Ask for confirmation of the current configuration, what is included and whether further mechanical development or validation is needed.
