AEM WIDEBAND X SERIES 30-0300 ISSUE

I just replaced my AEM Wideband 30-4110 with a 30-0300 X Series.
But why does the datalog fluctuate when I use the AEM X Series 30-0300 in Smanager?
When I used the older version, the datalog in Smanager was perfectly normal.
Analog + in D10
Analog - in D22
12V in A25
Ground in A26
(AEM Wideband X Series 30-0300)

Analog input D10
Analog - (none)
12V in A25
Ground in A26
(AEM Wideband Old 30-4110)

My question is, should the analog (-) be connected to the analog ground on the board?
All replies are greatly appreciated.

Try connecting the analog ground and see if that helps, it can be connected to the ground on the K-Pro board.

The analog ground needs to be hooked up to D22.
