i have the lm2 and i have the positive green wire goin to port one of the mpvi pro, and i have the yellow ground wire going to port 5, i also have a wire coming out of port 5 going straight to the battery ground. i can see lm2 wideband on my table and guages(blank data tho) but it doesnt show any info in my histograms under afr error either. so im pretty lost. not sure where i went wrong.

im also trying to do a 2 bar map tune on a 2004 silverado. thanks of any help, ill try to post up my config file for you guys to look over.
