    can't see wideband in chart vs time

    I got a MPVI3 +pro link and LC-2 wideband

    I connected my wideband in input 1 (red), used the innovate software to zero my ground.
    (set 0.50v at lambda: 0.5 and 0.50v at lambda: 1.5 =reading of 0.53v in channel.
    I set 4.50v at lambda: 0.5 and 4.50v at lambda: 1.5 =reading of 4.59v in channel)

    with excel I found the formula (X/3.9016777)+0.3695=lambda X=volt


    NOW HERE THE ISSUE
    I see my lambda reading in "Channels" on left side but and can't get a reading in "Chart vs. Time"

    You need to have RPM on the left side of your chart

    I figured out.
    the air fuel ratio for my wb don't read anything, until I used equivalence ratio. But now the issue was my commanded is only in AFR.
    I used math - user -to convert commanded AFR to lambda
    -for the MAF calibration formula
