I ran it twice during opening day at the track this year. I let the
tranny shift by itself and then did a manual shift run. Both runs gave
15.8x. This computer was also recalibrated for 5600 rpm shift points
(shifts were dead on on both runs). 60' times were 2.289 and 2.303.
1/8 times were 10.127 and 10.171. On the third run, I swapped in my
'96 MP PCM and promptly ran a 15.2x with lower manual shift points (~5000)
and had problems getting the 2-3 upshift. 60' time was 2.121 and 1/8 time
was 9.631
No more runs that day as it was free entry and every vehicle in Ontario
must have been there :-)

BTW, I also recorded the '97 MP PCM CA version (no fed version for the auto.).
Under WOT, spark advance ranged from 7 to 28 degrees advance. There is a
22 to 7 degree retard at the 1-2 shift and a 26 to 15 degrees retard at the
2-3 shift (for CA emission standards, I believe). Two runs with this computer
gave a 15.854 (auto. shift) and a 15.523 (manual shift). The third run
with the '96 MP PCM got me a 14.908.
