Chrysler MAP correction - Adds the ability to correct instantaneous fuel injector pulse readings by a generated factor that is based off of MAP sensor readings. This is needed on late model Chrysler vehicles that have a constant fuel system pressure, as this translates directly into variable fuel injector differential pressure that the MPGuino is not normally capable of addressing. Adds 7 stored settings. Adds 1548 bytes (so far). This is a work in progress.
One question. Are you reading OBD? As i remember MPGuino has just two input signals. Pulse from injector and pulse from VSS. So how do you get MAP readings or why do you need OBDII filtering?

Anyway I trully appreciate your effort and hoping that I'll be able to test your code soon. It has so many great features.
