The MAP wire is not connected solid. I would strip back some of the wire and solder that bad boy on. On some cars the tap just won't work. I had to do the same with my car, because it was hunting for a signal.

To check to see if your voltage is wright unplug the controller and use a multimeter. Touch the green wire and the ground with the car on and it should read 2.5 volts. If it's jumping around then your connection is bad and the controller will freak out.

This is one of the reasons we came up with the MAP piggyback. Most map sensor wires are at a severe point of heat fatigue from there location. Try to stay around 2" from the end of the connecotor.
