Seems to work just fine with my MS3 Basic, although I haven't confirmed the readings against a dedicated temp sensor or anything. The numbers in the datalogs pass the bullshit test, though. No special setup required.

It also works for me. Passes the bullshit test. Right around ambient.

pulse width of 1 millisecond represents a fuel temperature of -40 degrees C and a pulse width of 5 milliseconds represents a temperature of 125 degrees C.

I found my answer: Haltech Sports range of ECU don't support multiple channels off a single input which is why I'm not getting the fuel temp. Hook it up to the Elite or Pro range of ECU's and you'll get both fuel composition and temp.
