Temp Sensor Spacers, Where can I get 'em Options

[76-914]

Sorry guys I just read a thread on these spacers where a guy has them for $24 ea. but I can't find thread and I'm a dumb shit with search features. (IMG:style_emoticons/default/chair.gif)

Just PM Brad Mayeur and he'll set you up.

FWIW, installing this spacer is the best thing I've done in years to make my car run better. No more surging and crappy idle while warming up, and it doesn't screw up the mixture once the engine is warmed up (as does a ballast resistor).

The heads must heat up and cool off quite rapidly. What do people who have a VDO head temperature gauge see on their cars?

BTW, Brad Mayeur made a comment that I suspect explains how this problem came about. He said the 1.7's don't have this problem. Since they preceded the 2.0's, I suspect that the CHT's NTC resistor characteristics were chosen for that engine, and to cut costs, Bosch/Porsche eventually decided not to go with a different CHT for the 2.0L's, which seem to want a richer warm-up mixture (perhaps due to the increased cylinder and piston surface area?). They did use a different sensor on the first 2.0's ('73), but that was likely due to their use of the same ECU as the 1.7's, and it helped the engine run richer overall to help deal with the fact that the 1.7 ECU didn't have the right speed correction board in it. I suspect the ballast resistor they used was partially an attempt to improve the warm-up behavior. Once the 2.0L ECU's came out, they reverted to the 1.7's CHT and dropped the ballast resistor.
