You need a wideband lambda. A good and working setup is to replace your secondary lambda with AEM UEGO, and route the analog 0-5V output from AEM to ECU's SO2 input. By doing this, A/F ratios can be monitored while driving with the gauge, and also datalogging the A/F works great! Downside is that in datalogs A/F is shown only as a SO2 voltage value, but it's no big deal. Also, OBD II must be disabled to turn off the CEL caused by removing the secondary lambda.

Yes, like I said above you can see the A/F values (shown as voltage level) by looking at the sensor SO2 in KManager.
