    Being a Delphi I have high hopes.

    The MAT would be Ohms just like an IAT or CTS. Then used in 256 bit in PCM and there's a table for that in $0D.

    The MAP is a 5 volt reference, (Specs from link) 0.25 to 4.75 VDC depending on MAP/Vacuum and there's a chart in the link but no real specs, or do I know of exact specs for regualr MAP sensor?

    But looks like four sensors and some good for boost. Differant styles to, one with bolt hole so I'm guessing it would be a boosted application.
    • 15 kPa to 102 kPa Normally Aspirated
    • 12.5 kPa to 115 kPa Would work?
    • 20 kPa to 250 kPa 2 bar
    • 10 kPa to 350 kPa 3 bar

    EDIT: Here's some good info on GM MAP sensors:

    I don't remember where I found it, but I have used this(Volts/Vacuum/Kpa), and it pretty much matches up to what Mark posted.

    Nice!

    When you get that close remember that Barometric pressure has to be accounted for.

    Definately keeping a eye on this thread. If this sensor ends up working out, it would make a nice little addition to my wrangler when I do the gm ecm swap on it. It would help clean up under the hood a bit, eleminating some wire, vaccum fiting/hose, and the map sensor itself from the large bracket mounted to the firewall.
