Generic CAN (GCAN) — Current Beta Feature

Haltech identifies this Nexus ECU / display platform as eligible for Generic CAN (GCAN), its user-programmable CAN messaging feature. GCAN is provided at no additional licence cost on eligible Nexus hardware and can also be enabled on existing eligible units through the applicable firmware update.

• Create custom CAN messages for supported third-party devices and systems.
• Useful for OEM dash retention, CAN sensors, steering-wheel / switch controls, ABS data, loggers and other custom CAN integrations.
• Haltech currently specifies support for up to 30 CAN frames and 200 signals.

Important: GCAN is currently released by Haltech as a beta feature. Access requires opting into the applicable beta software / firmware through NSP. Check Haltech's current GCAN release instructions before updating, back up the existing configuration first and verify all connected-device operation after the update.
