Well .... I bought the car with the CIS mods already on it so while I do not have the original dizzy and WUR, I did have the forethought to buy another pelicans used WUR (same year U.S car) just in case. I had it tested by Tony on this forum, and he concluded it needs a refurbish. Since I was waiting on a brand new digital WUR at that time, I decided to save the refurbishment for later .... I have been told by the DWUR tech that once I have the rest of the CIS system components functional again, it should be an easy software update in order to produce the desired cold - to - warm control pressure and rate of delivery defaults on my unit. Why this was not done by the installer who assured me of his ability to "dial me in" (and proved it by his premium priced invoice ), I can only guess.
By the way, I mentioned previously that the WUR did not have a functioning vacuum hose connected to it (the one the installer connected had no active vacuum), but that I had found one just below the fiber jacketed one that he used, that did have a vacuum that I tested to be around 15-20 bar up to around 2 to 2.5 thousand rpm, and then dropped to zero. Does this sound like the kind of vacuum input I am looking for for a typical WUR application ? It is the one that is connected now.
As to the 15 C temp switch, mine is gold colored and has a flat tab coming from it as a connection point for the wire. Are you saying that at the cold temperature (I measured it by shooting a laser thermometer at the base of the switch) of 75 F , that the light on the continuity tester SHOULD have lit when tested at the disconnected switches flat tab ?
Also, am I correct in assuming that the lack of a readable voltage measured at the 02 sensor was probably not because the mixture was set at a ridiculously lean mixture, and that it was more likely malfunctioning ? I also did not see any shielding whatsoever on the lead running from the sensor to the connector .... just a small diameter black wire. And yes, the same folks installed the new sensor at the same time they installed the digital WUR.
Lastly, when I do get this digital WUR programmed, what would be ideal cold and warm - and rate of transition between the two - control pressures ?
Fun, fun, fun ....
Thanks !
Bill
