This post is explain how to datalog boost using a Raptor. The best and only real way to do this is to get a GM 3 Bar map sensor and hook it into the Raptor.
The GM 3 Bar Map sensor is the one used by FAST and DFI and is very accurate. If you purchase this sensor at a local dealer or through Napa it can be very expensive (up to $100). Save yourself some money and get it for half the price.
Go to
http://www.gmpartsdirect.com (thanks Ken B for the source) and put in part #12223861. It costs $55.04. Do yourself a favor and also get the wiring harness for the sensor Part #15305891 for $18.79. The install will be much cleaner if you plan on exposing the sensor.
Once you get the parts there are 4 different steps to this install.
1. Hook up the vacuum line to the 3 bar sensor
2. Wire the 3 bar map sensor
3. Wire the sensor to the raptor
4. Configure the raptor
Step 1: Hook up the vacuum line to the 3 bar map sensor.
This is very easy. There is only one vacuum port on the sensor. Take your vacuum source and cut it. Buy a Vacuum T and slit the signal so that it also goes to the 3 bar sensor. For those with 03-04 cobras this can all be done behind the glove compartment which is where the boost source line is. I have an 04 cobra and keep my 3 bar sensor behind the glove compartment so that its completely hidden.
Step 2: Wire the 3 bar map sensor
You will need a 5V source to supply power to the sensor. The perfect source is the TPS sensor. Depending upon what year and make of your car it will be a little different. The best way thing to do is to disconnect the plug to the TPS sensor, and then turn the key on the car without starting it up. Take a multimeter and see what pin is (+)5 volts. You might read as high as 7 volts. That is ok. Before you do any wiring always make sure the key is out of the ignition.Take the 5 volts to Pin C on the sensor. Take a good ground and connect it to pin A on the sensor, and then you'll take Pin B and wire it to the raptor. See next step.
Step 3: Wire the sensor to the Raptor
Before you wire this step make sure the Raptor isn't powered up to the Laptop or that the raptor isn't plugged into the OBD2 port.
Take Pin B of the 3 bar sensor and wire it to the analog cable on the raptor. I used analog 3 of the raptor which is the thin orange wire on the analog cable. You can use anyone you want. Make sure that you ground red if aren't already using the Raptor to monitor a/f. Here is a chart of the wires.
Analog 1 - Black
Analog 2 - Brown
Analog 3 - Orange
Analog 4 - Green
Ground - Red (shield also works)
Step 4: Configure the Raptor
Once the Raptor is powered up and connected to the car follow these directions.
1. Go under configure and make sure that you sure you check the analog input you are using.
2. Go under analog configuration and put the formula in for the analog input that you assigned the 3 Bar map sensor.
3. The formula is V*9-14.7 Make sure you put in -14.7 on the 2nd half of the equation.
You should now be good to go. Once you start monitoring the analog input that you assigned the map sensor you will see a negative number when the car is idling or part throttle under vacuum. Once your car starts generating boost you see the number go positive and reflect your actual boost number.
I think I just answered my own question.
:
. I used a AEM gauge with singe wide band O2 drilled into the exhaust after the first cat. 
I should have gone to sleep at around 2 am, I mean 12-1 is much safer, i'll change that. I really hope that paint stays that way, used epoxy primer on a bare wheel abrated block and painted with PPG? urethane paint in the body color code.
I apologize for my ignorance, But when you say run the wires from the MAP sensor into the cab...What wires are you referring to? Is there a wire harness I need? None was included with the Map sensor. Though I did purchase the pig tail connector for it. The wideband I understand.
