Afr500can and prolink

[ns158sl]

I finally am trying out a afm500can with a mpvi2 with prolink. I have 5.04v vcm suite. The afr reads close to the wideband but the lambda reading ranges from 4 to 60s... Trying to dial in math for gmve and that is not working and am starting to think it is to do with the wonky lambda reading. I have the can directly wires to prolink, and yes the can +/- are correct, obviously because the afr output is reading right. I am using math 6059 also which seemed to be the only option that would work. Any insight on what I'm missing?

Did you have the software match the jumper setting? I know if the jumper is on extreme and you input standard range in the ballenger software it will be off.
