No you were right because I checked the manual and they say at sea level it should read 101Kpa.
A=ground
B=signal
C=5volts
Soooo I did a resistance check from A-C (2.08)and then from A-B (4.56)and C-B(6.65)ohms
The higher resistance is in the wrong spot?
I connected it up with the Power and ground swaped and wala!! 4.8 volts
I am going to hook it up with the A-C wires swapped
What do you think?

I am not familiar with your MAP sensor to figure out as to which wires go where.
Get the specs for the MAP sensor and figure out what the input/output wires are.
Is it possible that you have a 5 wire MAP sensor and you have just counted from the wrong end?
eg ABCDE is how you counted it, when it should be EDCBA.....

Colin I am getting a goo map signal now.
Thanks a lot for your help as I would have never guessed the map was wired backwards, as per the Tec-GT instructions I might add.
Anyway Thanks a lot Colin.

Thumbs up to them. I assume that 928 MS puts the kit together from components that they buy. This kit had a 3 bar MAP sensor in it for a boosted car.
Here is the replay from the TEC-GT fourm

Figured I would chime in. The wiring diagram that is shown in the manual is absolutely correct. As for the part number you listed in the email, this is for a 3 BAR sensor. If the program in the TECgt was set up for a 1 BAR sensor, then the reading you originally got would make sense. If the engine is not boosted, you may have received the incorrect MAP sensor. The orange connector is a dead giveaway that the sensor is not a 1 BAR, as they use a green connector with a different key. Hope this helps clear things up!
