need datasheet/info for SpeedPro wideband sensor...

[Romans, Mark]

I have a friend who is a Felpro dealer and if I remember correctly they use
a honda
wideband with a resistor that is coded to your ecm.  The 02 sensor is of
little use
without your ecm.  They charge a stupid amount of money to replace the
resistor and
since it's coded to your ecm, you can't just use any replacement Honda
wideband, you
have to use one you get from them.  He's been trying to figure out how to
bypass this
too. As far as I know it hasn't happened yet.
