Wideband O2 gauge readings inconsistent with Datalog

Anyone ever get these problems ?

My innovative gauge says 14.7.... my datalog output from the sensor is as much as 2 points above that.... even under load....

The setup is properly wired... but I suspect there is a voltage issue... anyone ?

What program are you using to datalog? With Crome, I have to use the offset to compensate and get the values more correct. Even then, the display on the laptop is often FAR off the display of the wideband. The averages recorded however are on target. Thats all that really matters in the end.

averages are correct ?

I use crome pro right now and yes, the offset is adjusted so that it matches up ON IDLE... but once I start to hit the engine with load... the laptop gives me very different numbers (haven't noticed if the RECORDED numbers are different from the real time display tho) I've been tuning with the wideband gauge instead... but I tune by myself and it is a long long process if the wideband output is not accurate... so I cannot just make a few pulls and re-tune asince I can't trust the figures in the laptop.
