Output ranges for sensors, need info

[John Larkin]

I looked through gnttype but didn't find what I was looking for. I'd like to find a source for voltage coorelations to output for various sensors. MAF, MAP, TPS (no brainer there), ESC, and so forth. Any ideas?

MAF
30-140 Hz or 3 to 255 gm/sec
MAP
0-5v 0-200 K/Pa
TPS
0-5v 0-100% TPS
CTS
resistive effectively 10K-100 ohms
MAT
same as coolant

Thanks Bruce. Hopefully in the next few weeks I can hook up the WB02 and my newly acquired Dataq logger and get some tables set up. I'm planning to get a 3-bar MAP also for boost logging. Will the parameters for MAP you listed still be valid for the 3-bar? Any extra info such as how those voltage levels coorelate to values normally seen on a ScanMaster that are recalc'd for display purposes (read output) would be appreciated. This is DIY-Datalogger.org, hehe. Increments and linearity rules would be appreciated as well.

3 BAR is 0 - 300 kpa (3 atmospheres) relative to perfect vacuum.

Basically that's -30 InHg to 29+ psi of boost referenced to atmosphere.

0-5 volts again.

For the water temp sender, here is a temp vs. resistence curve. This is from a GM manual I believe. I ran a test on a sensor I bought and got pretty close to this:

100C = 177 ohms
90C = 241
80C =332
70C = 467
60C = 667
50C = 973
40C = 1459
30C = 2238
20C = 3520
10C = 5670
0C = 9420
-20C = 28680
-40C = 100700

Thanks so much everyone! I'm still hungry if anyone has more info! Thank you.
