I want to cover all my bases here. I have purchased the new GB CHT sensor from 914Rubber to try.
So, I think I will buy a spacer from Brad Mayeur to have the option. From what he says it should: "Porsche 914/4 Cylinder Head Temperature Sensor Extension. This little device slows down the heating of the sensor and improves warm up drivability." I do have "warm up drivability" problems = Low idle RPM until the VDO CHT hits about 250*F. So it seems like my problems don't need the warm up to slow down, it needs to SPEED UP.

One thing I always know for sure: If I draw a circuit, somebody else can draw it better (IMG:style_emoticons/default/smile.gif) . That's why I ran away from design as fast as I could.
