Adjustable MAP for Newer XJ's?

I have a 2000 XJ, the MAP sensor is on the throttle body- is this the same as the older ones in term of wiring it? It has different wire colors, but i can figure them out... two of the wires read 5v.... 4.97 on one and 5.13 on the other with vehicle off but ignition on. My question is if anyone has researched this, or even done this on a newer XJ with the TB mounted sensor.

I haven't seen anyone do this - and the OBDII computer in the 97+ XJ's will probably come up with error codes and create problems with emission testing.
