 ## 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)

+* 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.
