TCC lockup - which scheme would give better performance?

[Roger Heflin]

Ok,

I have pretty much disassembled and deciphered the TCC lockup code,
and I feel I can add some code for a TCC lockup scheme, but I don't
want to go to the trouble of adding it if it won't help.

Without code changes (only data)

The current lockup occurs at 95 mph, which is way down in my rpm range for my engine,
about 4400 before lockup, 4000 after lookup.  I am going to change this so that it locks
up just before the end of the 1/4, somewhere around 105 or so.  

No code change required for this:
The second choice is to lock it up at say 76 in second gear and let it stayed locked
through 3rd also.

Here is the scheme that requires code adjustment:

The third choice is to lock it at 76 in 2nd, unlock it in the lower rpms in 3rd and lock
it back up just before the end of the quarter in 3rd.  The idea is to get the engine more
quickly through the lower rpms,
and lock the converter at the best moment to keep things around the
power band.  76 mph in 2nd puts me just a bit higher than my HP peak.  The locking before
the end of the 1/4 is because the car lurches pretty hard when the convertor locks, and
currently after it lurchs the engine hits low rpms and more slowly accelerates.

I know the GN guys had some schemes, are they similar to what I have and which one worked
the best?

I am also considering more serious code changes, such as adjustments to allow less fuel to
be injected in 1st and 2nd to get a more optimal mixture.
