Haltech TCA

Supported Signals

Thermocouple amplifier decoded from the Haltech TCA-2, TCA-4 and TCA-8 at 1 Mbit/s. Temperatures only.

1 Mbit/s 11-bit Standard IDs

Pick the variant in the gauge's settings rather than as a separate ECU type — TCA-4 box A or B, TCA-8 for both, TCA-2 box A or B, or a TCA-2 pair. Set the CAN bus speed to 1 Mbit/s. The module can run alongside an ECU on the same bus.
