alternate wideband displays

[DOHCAccord]

Anyone have any ideas on how to check the wideband readout against the laptop display. i got my wideband today but the display is backordered or whatever it really is. I want to install the wideband, hook it up to my ecu, and have it all ready to go, but i want to be able to check the readout from the wideband against what the laptop is showing. any ideas??
