I tackled the Throttle Load Axis Variable (it is used heavily to
determine TCC lockup).   I still don't understand exactly what
is is calculating, if someone wants to look at the flowchart,
it is at http://www.hit.net/~rah/F43B_F4C6.gif .    The 
part of the code that I don't understand the purpose of is the
A = A - B part, I don't understand exactly why.  The rest of
things are pretty clear.  I have the things that confuse me
marked as such.

Ok,  I found the limits of the TPS voltage.  If the voltage is
less than 0x0C or greater than 0xF6 then it uses 0x38 as the default value.  I expect with
the TPS failed things may run pretty odd.
The above limits are pretty clear from the flowchart.
