Lm2 wideband jumping reading

[wall-ace]

Hi im setting up my hp tuner 3.2 scanner. And add my lm 2 wideband. The problem is the reading on my scanner is different from my wideband. My wide band sits on 14.2 and my scanner jumps 14 to 15 so fast i cant even read it. Has anybody else came across this?? Thanks

got a good earth for your wideband kit? Some require you to use the same earth as the ecu

I changed earths for both my laptop and wideband still hasn't helped. My if i replay my data the afr jumps .8 from the reading of my wideband.
