Default Wide band logging 0-5 v output problem

Just wondering if anybody has has similar issues as this and possible fixes.
The problem I am having is the 0-5 output from the wideband that i have to plug into my v2 reads different than what I am seeing on my gauge. It's very difficult to make proper adjustments to my ve table with it reading lean on my Ben chart but I can look at my gauge during the run and its a constant 11.2 afr. The 0-5 output reads .8 leaner than what I see on my gauge. How do I fix???
Using a LC-1 btw

Open up the calc.pid file in the EFI live folder on your hard drive (documents --> user configuration) and find the PID for the LC-1 AFR. The equation is probably incorrect. I know I had to change it when I used an LC-1.

Make sure your 0-5v input has a good ground to reference 0v from. Sometimes with a floating ground, unwanted potential can skew apparent sensor output. Some widebands are sensitive, some aren't. I've seen the LC-1 dance around without a group input before.
