  Subject: Air Pressure Transducer
  Does anyone know of a source for a fairly low cost Air Pressure
  Transducer that measures positive and negative gauge pressure?
  It doesn't have to measure extreme pressures.  I'm looking for a
  transducer that will measure boost pressures of up to 30 psi and
  vacuum down to - 14.7 psi.  It would also be helpful if the
  transducer was linear in measurement.  Any help on any transducers>>>
  
  The GM 3 bar MAP sensor is about $50 from the "discount" GM parts 
  dealers; I use it to log boost on the turbo Regal. Call 'em up, 
  order one and you're good to go!
  
  <<<cheaper, etc., etc.)  but it's B-I-G !  it's got connectors (the
  bane of any high rel app).  it's got so damm much VLSI ASIC's it's>>>
  
  We have a test facility called HALT (Highly Accelerated 
  Lifecycle Testing) that shakes, heats, freezes, etc the system
  boards until failure is observed. The operator I speak with often
  expresses his amazement at how far the boards have to be pushed
  before failure occurs. Oscillatory excursions of several inches 
  p-p for a board with add-in cpu cards, mem card (and IDE, SCSI 
  connecters) hanging on for dear life is not uncommon.
  
  <<<   So all these autos in the films is fairly accurate then... what 
  do you guys out there in DIY EFI land prefer? (Manual or automatic 
  transmission)   >>>
  
  Well for turbo apps the automatic is a better choice (IMO) for full
  throttle acceleration, at least for keeping the turbo singing happily
  along during the shifts...
