Just a moment ago I was monitoring my cars water temperature with my new PFC and noticed that after a quick drive I had peaked at 99C, and the fans had not turned on! Now if I turn on the AC the fans immediately turn on and cool my car down to 91C. Is there some way for me to specify when the fans should turn on? When should they kick on with out the AC on? Is it time form me to test to see if the fans are operational by giving them the old flick test, and if I do find that are working, should I move on to testing the fan solenoids. How do I set what temperature to turn on the fans? Does the driving light trick still work? How can I prevent this from happening again?
Thanks in advance.

99C = 210F, not hot enough for the fans to come on with standard Mazda RX-7 programming values. The thermoswitch is set at 226F.

the 226F or 108C switch is one thing, it works independently of thermosensor. it just flips fans on if i reaches that temp. The PFC operates differently than stock mazda. On my car the fans come on at 99C. The fact that your peak value was 99C probably means that they did come on. If not something is wrong, would haev to be a realy or something.

BTW, I have the 108C thermoswtich for sale if you want, adds 10-15 rwhp and is new in the box. I will sell it for 40$
