3. Common Problems:

RPM Signal off by half (1G)

* Because of the way that Mitsubishi triggers the ignition coils, this is normal. To fix it, just set the Cylinders to "2"

Car runs like crap, wont rev past 2-3K rpm, No change in the Hz reading on the Karman display

* You read the wrong section in the manual and chose the yellow and white wires to modify the airflow signal. Wrong, you should have used the pink and orange wires.* You have a bad connection on either the pink or orange wire.* You have the pink and orange wires reversed.* You didn't select "Karman" for the air flow meter type.

No display or other power problems

* You have been swinging the AFC around by the wire harness. This will pull the harness out of its internal socket. To check it or fix it, carefully unscrew the back cover with the proper small size Phillips screwdriver. Make sure the little connectors are plugged in all the way.
