No success here, either, Mike.  The only way I was able to get anything
out of it was to swap in a PROM from the 3.1L engine and use Andy
Whittaker's FreeScan.  I can get most everything then except, because
the VSS input location is different on the 3.1 PROM versus my 2.8 PROM,
I don't get any VSS related info, nor highway fuel, nor EGR blah blah
blah.  I'm still looking for a program to read the 2.8 ALDL and for a
$6D mask editor.  For once, I may need to get off my lazy butt and work
on it some myself.  Egads, the though....
