Standalone CAN wideband controller decoded from the Haltech WB1 and WB2 at 1 Mbit/s, updating at 20 Hz.
Choose the device in the gauge's settings — WB1, or WB2 device A, B, C or D — which selects the pair of WBC channels the gauge listens for. Set the CAN bus speed to 1 Mbit/s. Channel 1 also drives the generic AFR and wideband bank 1 signals. A channel reporting a sensor fault blanks rather than showing a stale value.
