My understanding of the fan switch from the S4/A6 which is mounted in the lower part of the rad hose is that once it reaches a certain temperature, it closes a circuit, for two different circuits and at two different temperatures. Has anyone considered using that simply to trigger the fan relays, which the Boxster ECU normally does?
Otherwise, this guy makes some nice fan controllers that look like they will work nicely with the Boxster:

Mind sharing the file?

I'm going to be doing some canbus sniffing in about a week or so. Might be able to get this stuff working properly with a arduino board. A local friend had to do this with his RX8/LS swap.
I'm also debating going with an EMU Black stand-alone instead of the factory Motronic. That's a pretty sweet ECU.
