Fuel-It! CANfuel is a next-generation CANbus sequential port fuel injection controller designed to let your ECU run up to 8 port injectors with precise sequential control, while adding extensive sensor I/O and auxiliary control. Ideal for BMW G, F and E chassis applications, it delivers an easier install, robust safety features and exceptional flexibility in a rugged, weatherproof aluminium enclosure with a quality plug-and-play harness system.
- Controls up to 8 port fuel injectors sequentially via your ECU over CANbus
- Expanded I/O for performance builds: 8 analogue inputs, 3 digital inputs, 2 EGT probe inputs and 5 analogue outputs
- Four high-current PWM outputs sourcing 12 V for reliable control of external boost solenoids, relays, line lock, pumps and more
- Built-in safety strategy that falls back to batch-fire if crank sync is lost
- Bluetooth connectivity with a free Android and iOS app for monitoring, logging, real-time tuning and firmware updates
- Weatherproof aluminium housing and plug-and-play harness options for BMW platforms
BMW harness options
G Chassis harness fits all G chassis automatic transmission vehicles. The universal harness suits other BMW applications including G chassis manual transmission, F chassis and E chassis.
Operating modes
- JB4 Slave Mode available now: Full integration with JB4 for seamless control of sequential port injection, ethanol content and low fuel pressure inputs, external boost solenoids, injection status monitoring and more via the JB4 app. Includes JB4 port injection strategies for tip-in, auto-tuning based on ethanol mixture and low fuel pressure scaling. For unlocked ECUs, free unlocked MHD backend flash maps enable real-time ECU scaling based on port injection volume and ethanol content.
- Stand-Alone Operation coming soon: Direct PI mapping through the free CANfuel Bluetooth app featuring a 32x32 primary injection table and modifiers for ethanol content, fuel pressure, tip-in, EGT and full external boost PID control, with real-time adjustment in-app.
- ECU Slave Mode coming soon: Integration with a custom MHD-tuned ECU to control port injection and external boost solenoids, read external inputs and monitor injection status.
Designed for easier installs
High-current PWM outputs are configured to source 12 V so you simply ground the opposite side of your solenoid or relay for clean, reliable wiring. With industry-leading I/O, including built-in 5 V reference and signal ground pins, you have the headroom to add ethanol sensors, low fuel pressure monitoring, additional pressure sensors, EGT probes, external pumps and more.
