Will hp tuners log dual widebands via usb using the innovate lm2 3807 unit? If so how would I do it. Looking to purchase one for doing carb and efi tuning. Thanks for your time guys!

Hey Joshua, good question and this isn't something I've done personally. I don't believe you can log dual widebands into the scanner via serial (which is my preferred option where possible), however I can't see why you wouldn't be able to wire both widebands into separate AN voltage inputs on the MPVI interface. If you do this then you need to be mindful of ground offsets that can affect the accuracy of your data.
