Supported Channels

This integration supports the following channels:

  • RPM
  • EcuVolts
  • IAT
  • EngineTemp
  • TPS
  • MAP
  • InjectorPW
  • Ignition
  • Knock
  • CamTiming


Connecting to the Hondata system requires two wires:

  • CAN1 High from RaceCapture to CAN high of the Hondata system.
  • CAN1 Low from RaceCapture to CAN low of the Hondata system.

For RaceCapture wiring, see the CAN integration guide for wiring details.

Note: Ensure RaceCapture and the Hondata system are grounded to a common location to prevent CAN bus data errors.

If you are unsure about how to wire the Hondata ECU, or what connections to use, please contact Hondata for support.

CAN termination

The KPro4 does not have built-in CAN termination. You will need to also connect a 120 ohm resistor across the CAN High / CAN Low connections at the connections to the KPro4.

CAN preset

Under CAN Bus, select 500Kbps for the baud rate and Termination On. CANBUSBaudRate.png
