Just a wild guess, that is why I would like to try to disconnect the Zeitronix to start with then do a diagnostic measurement on the map sensor according to the Crossfire manual.
Makes total sense... wires are wires, at the end of the day. If you load too many things on a small gauge wire like that, it can affect the items at the end of it (MAP sensor, in this case).
