How many WBO over CAN

Post by Chybber »

Let's say I want to connect like 6 widebands to measure individual cylinders on a 6 cylinder engine.
I run the engine on a uaEFI could I connect 3 "Dual WBO channel" https://www.shop.rusefi.com/shop/p/dual-channel-wbo over CANbus
Would that work?

For WBO you can sen any of 256 CAN ID offset. It needs two CANID (transmits two packets). So you can add up to 128 devices on one bus.
For RusEFI FW, currently only two CAN WBOs are supported https://github.com/rusefi/rusefi/blob/fb7df80694e7f69c2558b0ea8ed415a71b13bbe7/firmware/init/sensor/init_lambda.cpp#L32 . But we can add few more.
