If ya'll wanna send me a copy I can compare it to a old version, and tell ya
the difference..
  If you unplugged the 9th injector then ya could run the AUJN Bin, and the
fan locations have been posted (the AUJN runs the same locations as the
ARAP, just it's a manual trannny version), and the formulas are at
programming 101.
