 ## 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)
