This is true. But then, if one had a known good AFM, one wouldn't being
having this problem, either. Just because the one on yer buddy's van works
doesn't mean it's calibrated correctly. I guess what we'd be talking about
is a new OEM AFM right out of the box.

It seems to me there were postings here a few years ago by someone who had
figured out the voltage outputs. I'll do a search and post results if I find
any.
