Unless you live in a location at or below freezing, the thermoswitch/TTS (temp driven ground for the CSV electrical circuit) will not activate and the CSV is never called into service to provide fuel. They become a problem when it leaks though (too rich) even in warm climates. Suggest that these are only needed by the cold climate folks and everyone else should just delete or disconnect them.
TS/TTS values (from Anders):
311 906 161 : -12 to -18 deg. C / 10 to 0 deg. F
311 906 161 A : 0 to -10 deg. C / 32 to 14 deg. F
311 906 161 B : -2 to -8 deg. C / 28 to 18 deg. F
311 906 161 C : -6 to -14 deg. C / 21 to 7 deg. F
Jeff,
Thanx for the info, & it's generally true - but the caveat is that nobody then takes their 914 somewhere with cold enough temperatures for it to kick in, such as on higher mountain passes or Pike's Peak or something on a rally or group drive, etc.
Some of our 914world drives up to Palomar Mountain, Big Bear, Lake Arrowhead, Mount Baldy, etc. can run into conditions for much of the year where the CSV would be needed & kick in to start the car. I'm sure other areas in the Southwest, Southeast, etc. probably also have higher elevations where it gets cold.
And of course - you find the twisties on those mountains!
Over past years I have taken my 914 up to the local SoCal mountains, Mammoth, Tahoe all in CA, Ashland OR, Park City & Brianhead UT, CO/UT I-70, etc. - & may take my 914 to such cold condition areas again in the future once back on the road, & also prefer to keep my EFI complete & intact.
So anyone who may use their 914 at some point in that way, should keep their CSV.
