## rusEFI Wide band oxygen
rusEFI has two probably working implementations for Bosch wideband oxygen control:
* We have cj125 integration
* We like [https://github.com/mck1117/wideband](https://github.com/mck1117/wideband) even more. See [the forum thread](https://rusefi.com/forum/viewtopic.php?f=4&t=1856)
## rusEFI wideband module
* [https://github.com/mck1117/wideband](https://github.com/mck1117/wideband) is what we use [the forum thread](https://rusefi.com/forum/viewtopic.php?f=4&t=1856)
See [rusEFI-Wideband-Controller](rusEFI-Wideband-Controller)
See [Hellen-WBO](Hellen-WBO)
TODO: document it better
## cj125 troubleshooting
We have a few rusEFI console commands relevant for cj125
``cj125_info``
``cj125_restart``
``cj125_calibrate``

AndreiKA says Prometheus works
Matthew says 0.3 SOIC-24 boards works
Wideband controller based on Bosch CJ125 chip
green is vUr, temperature feedback
red is duty cycle
yellow is vUa, the lambda current measurement
white is converted AFR
fully operating in <30 seconds
in to closed loop in ~18 seconds
P=30
I=5
D=0.3
though you could probably use D=0 since the system is already damped so hard

## CJ125
* CJ125 is an unavailable older old chip replaced by CJ135. CJ125 is not available from legit distributors for many years now. There is no documentation for CJ135. Some time ago we chose to no longer spend resources on CJ125.
