You can find it at http://www.diy-efi.org with a simple search.
You remember highschool algebra? Grab some graph paper, you get 1.6 volts at 1 atm and 5 volts at 29 psi above atm. The output of the GM 3 bar - or any non-Ford MAP - is linear and graphs as a straight line.

Yeah, that's a 1 bar sensor for NA use.
1 bar ~ 100 kpa. The first bar gets you to atmospheric, more or less.
