## External WBO
|
|
|
|
* External controller with analog output, like then AEM 30-4110 and similar products.
|
|
* External controller with CAN interface, like the AEM X-Series wideband controller/gauge.

## CJ125
|
|
|
|
* CJ125 is an unavailable 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.
