GM MAP Sensor 2 bar

[Zak - Andrew Wakeling]

Hey guys,

Dad and I went through the procedure of mapping out a 2-bar and a 3-bar 
MAP sensor, and I too am puzzled why GM/Bosch/Delco/Delphi are keeping 
such facts a secret, not to mention other sensors like wide-band o2s, 
coolant temps, iac etc... I mean, its not like we're going to develop 
Delco computers or anything! (and don't any of you get ideas... hehe)

Anyway, enough of my ranting... I'm not 100% of these figures, but we 
did spend a considerable time boosting the sensors up with a compressor 
etc, and using a digital gauge to measure PSI, so if they're not exactly 
right, they're CLOSE.
Anyway, I've put the file in this url:
http://www.cse.unsw.edu.au/~akwa622/gmecm/

Its a excel file, and its got dec/hex, volts, 1-bar, 2-bar, 3-bar.. so 
its still good for a heap of things. I've even got the formula's in the 
excel sheet (even though they're straight line), so you can go and check 
them out.

Hope you had a good holiday!

Btw, not to be politic or anything, but I've just installed Netscape 6, 
and its SLOW as buggery... so I suggest you stick with what you've got 
unless you're rigged with good hardware.

Cheers,
Andrew Wakeling
