User-definable inputs and outputs

  • 1 × 25A high-current output, configured as starter control by default.
  • 2 × analog voltage inputs.
  • 4 × synchronised pulsed inputs for voltage or frequency signals such as flex fuel.
  • 4 × low-side digital pulsed outputs for functions such as boost control.

Compatibility and installation notes

For factory port-injected Honda K-series engines. Automatic transmissions and low-impedance injectors are not supported. The supplied air temperature, knock and oxygen sensors replace the factory sensors.

Not supported: VTEC pressure switch, thermofan switch, transmission reverse switch, or serial communication with factory Honda DBW, BCM or ICC modules. Factory A/C request and coolant gauge functions through those modules are not retained. The factory Honda ETC module must be bypassed or removed so the Rebel K can control the throttle.

Optional injector harnesses — sold separately

  • HT-186013 i4 GT150 (USCAR EV6).
  • HT-186014 i4 Timer (EV1).
  • HT-186015 i4 Sumitomo (Denso).
