I have a WB O2 sensor that reports O2 percent, sensor temp and error status via CAN bus and I would like to use it with rusefi. It's the Ecotrons ALM und uses a Bosch LSU 4.9 sensor controlled with the CJ125. http://www.ecotrons.com/products/wideband_controller_alm-board/.
The sensor uses as standard the SAE J1939 protocol at 250Kbps. The manual claims that it can be re-programmed to use a different protocol, but so far I've been unable to make that work.
Here's an example of a recorded data package:
Code: Select all
3 0FF00 01 //page number
55 F7 //=63317 -> 20.54 %O2
FC FF //=65532 -> 15.99 lambda (need to re-check calculation- 15.99 seems wrong)
8B AF //=44939 -> 1053K sensor temp
1 0 //=1,0 -> no errors, and PWM duty cycle high is 1
4C //=76 -> PWM duty cycle low -> PWM duty cycle is 332
