DLP with AEM UEGO erratic reading

[thommo]

Hey guys
I just received my new DLP and have hooked it up to my old AEM UEGO. (one before the new LSU 4.9 sensor)
I am having some major issues with it. You can see it in my log file attached.
First this is how i have set it up.
Running it all on a Microsoft Surface Pro 3. (has one USB port)
I have the DLP and the PLMS cable plugged into a 4 port USB Hub and then an extension cable plugged into the laptop.
I have the UEGO grounded to the chassis and a wire from that chassis ground to the GND on the DLP.
I have the 0-5v UEGO on AUX 1 on the DLP.
As far as im aware i have it all setup as per the guide.
I have copied the Lookup table that comes with Nistune and pasted into the AFR 1 .csv.
When i bring up the wideband in Nistune i am seeing roughly a 1 AFR difference to the gauge reading.
And it wildly jumps around as you can see in the log.
Can anyone suggest what might be happening here?
Any help will be greatly appreciated
Thanks
Scott
