The MAP is not a Plug+Play, change item.  It's signal is also used for
figuring out barometric pressure.  So to change it means finding and
changing all the barometric calculations.  The Accel unit is probably
sold for use with a system they sell, that uses a 2 bar calibration.
  I've only heard of two guys change a ecm from one MAP sensor to
another range of MAP, both times was way over 6 months of work.
  Yours being a PCM, I'm assuming it's an auto tranny.  Means even
more work.   Clever use of a Haltech E6GM ecm might be an option.
