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.

Very nice. This seems closer to being realized. I gather Spoke’s revised UI switch still allows for adjusting lean and rich circuits.
I’m curious about the Isolate switch as you say the car would not run when open. What would be the effect of grounding the ECU CHT sensor lead on hot restart? I recall long ago when experiencing some intermittent bucking on acceleration, to test for a bad CHT sensor (engine hot) my mechanic simply disconnected the ECU lead and grounded it to neg. battery terminal (or was it just to ground – can’t remember), and the car ran fine. |
