MAP Sensor Outside of the Manifold

What's the purpose? I've got a 2002 Ducati Monster that has a combined MAP/IAT sensor. I'm assuming this because it has a single sensor and I found a diagram on the internets that shows a 5v input, output, C*, and ground. The whole little thing is tucked up under the dash, behind the headlight.

So I'm asking because ever since back in the day when I put pipes on it, it has a lean spot between 3 and 4k rpm. For some reason this 750s i.e. model is the one model a Power Commander or any other does not exist for. It is an oddity.

It seems to run a lot better in cooler weather than hot. The hotter it gets, the more it leans out. Thinking this sensor was just an IAT, my thoughts were to cheat it by finding the ohms @ 40* F and jumping it with a corresponding resistor. That's all up in the air now since it's a combined sensor.

What good is a MAP in ambient air? Do you think the cheating IAT method would work? I know we don't have these new fangled injector thingies on the KLR, but ya know...
