In case you don't know this already....
This system is very sensitive to wiring issues. It contains 2 internal potentiometers that the DME compares. What codes have you been getting? Note this type of issue does not light the check engine light.
In my case issues have usually been caused by a bad connection on one of the 6 wires.
