K-Pro V4 Wideband readings jumping up and down wildly

Hi guys,

Having an issue with an AEM X Series Wideband / K-Pro v4. The air fuel ratios during WOT pulls are jumping up and down wildly. There's no STFT's, as ''no WOT compensation'' is selected, so it's not wideband feedback causing it. It's a brand new AFR gauge and sensor. Wired into Analog0 and set up in the calibration as such.

I've included a copy of the datalog as well as the calibration if anyone has any feedback.

Cheers guys

Have checked the fuses in the engine bay? The error P1166 is probably the cause of the strange fuel status.
