Default Wideband offset

my buddy has a PLX wideband in his truck along with the PLX wideband gauge.
Problem is the gauge is reading 11.0AFR and im logging 10.0 AFR with EFI Live. Its 1.0 AFR thru out the whole spectrum.

How in the world do i correct this?

Tuning Speed density kinda sucks at the moment with this problem..

Just like the tile says. You need to adjust the wideband offset. There is a spreadsheet on hp tuners that you can plug in what it's reading on the gauge vs logging software and it will spit out a number that you subtract or add to the offset. Or you can just go and take .5 out of the offset and see it it reads closer or further away and fine tune the offset from there.

Right click in one of the primary table cells and click insert. Then your wideband should be under user defined. Just double click on your wideband and the offset formula should pop up.

What does the wideband gauge say?

Transfer function should be something like volts*2+10
