AEM 4110 will read but won't show tables

[motrhedx81]

I have the AEM 4110 AFR gauge. I have it set up in the channels and it reads, but it won't record when I try to set up tables for AFR Errors. Do I have something set up wrong?

I'm using the white wire from the gauge connected to the red wire from the pro-link.

This is a 2000 GMC L29 7.4/454 running on the black box PCM (0411 in plans but time limited at the moment).

log, channel, chart, table files attached for reference.

For those that may be interested... It looks like the GM black box (BB) has to use the 'low res' AFR commanded channel. And I needed to make my math point to the transform AFR parameter/channel. I reworked my math like HP told me and it worked.

Updated math, log, graphs files below for reference

Here's the response I got from HP on my ticket.
----------------------
Based on the AFR error XML channel provided, it is not set up with the proper channels.

​Commanded AFR is not being logged in the HPL log provided.

The AFR channel setup in the math equation is the raw voltage, you will want to use the transformed pid.

Instead of:
100 * ([30011.10] - [50121]) / [50121]

The equation should look like:
100 * ([40000] - [6001]) / [6001]

40000 being the 4110 transformed channel and 6001 being the AFR commanded. 6001 would need to be added to the channel list in order for this math to log.
