>78 MPH is it?

As pulled from the HAC...
L831D: FCB 76 ; UNLOCK PREVENTION THRESH, (76 MPH)

Dave - that's interesting.  I am saying that because I believe that the 
TC still locks up even if you modify the MPH and make it higher.  Could 
you give more detail on what you said about RPM readings changing internally? 
 I'm not quite following you but I want to :-)

heh heh ... no problem there :-)  I'm the one who referred TC to put this 
parameter into the definition file.  I pulled it from the anht_hac.pdf on 
ECMGuy's site.
