Maybe the following is also happening (?)
On some 'stock' computers, long term memory cell 15 (the WOT cell)
is being learned at roughly 30-45 mph with a slightly heavy throttle,
just before PE mode is entered. This is about the conditions that happen
when cars return down the access road from the end of the track.
The proposition is that mem loc 15 is being learned each time on the
return road after the run. Also, throughout an entire run down the track,
whatever has been learned in loc 15 is being used to affect fueling.
If the above is true for our computers as well, this means that consistent
fueling
from run to run is not possible as mem loc 15 has potential to learn on the
return
trip unless the compute is reset. Of course, this is just one variable
that we're looking at. I am sure that there are many other variables
that affect performance from one run to another.

BTW, I have only short term memory and it gets reset every few minutes.
