Does anyone know if it is possible to take an OEM GT500 MAP sensor, wire it into the factory location on a Coyote harness, then log that as a normal PID with VCM Scanner?

Being as they don't have one, I doubt it.
No, what I meant was to wire it into the MPVI and log that
Which sensor did you use MRRPMBRP?
Just a Bosch, this one:

Made a block of aluminum to bolt it to, then ran a vacuum hose to it, after blower to see vac/boost. Picked up a +5v power from another sensor that's on top of the motor.
I wired mine into the AC pressure sensor with a temporary adapter and logged AC pressure. Seems to work
Neat idea!
Interesting - PCM has an MAP input for sure as the software suggest - you can switch the MAP on in your tune and make and log it. But which one is it?
If you take a look at EB you can see that pin 33 is used for MAP signal voltage. And the same pin is used for AC pressure sensor in Coyote:

That's something i had hoped to explore and assumed existed but could never find a pinout for a map equipped car. I wonder what the EB uses for AC?
Pin 52 in another connector which is Knock sensor in Coyote - I can't guarantee they are the same but this might be the way.

Another way might be to use Oil Pressure sensor input . Non PP cars have 2 state oil pressure switch only and PP cars have actual oil pressure switch/transducer. I'm going to explore this way.

The 2013 GT500 Copperhead has a MAP sensor, so you should be able to run a MAP on a Copperhead Coyote IMO

I wish I could edit the title of this thread, since it was based on bad info... but the intention is still there.
The fact that many strategies have the [ECM] 44204 - MAP Sensor: Master enable/disable for MAP Sensor. switch; combined with the nGauge also listing a MAP Sensor Voltage as a loggable channel with a steady 0v signal, makes me think that there is a pin reserved for this.
Does anyone have a PCM pinout / wiring diagram for the Copperhead?
I have a MAP sensor wired in now and can log it with my nGauge, but sampling rate and limited channels make it less than ideal. I don't currently have the MPVI Pro interface, and honestly it's a pretty big expense, and more of a wiring hassle than one extra signal is worth.
