Electric fan install help.

After getting the FiTech, I see that I will want to use the Entropy controller, but, I still need to call them and fing out why I only have one speed on the fans. I spent an extra 40 bucks for thier LSX controller becuase it handles two speeds, but now I think maybe it only has that option if it's run by an ECU, not as stand alone. If that's the case I could've bought the cheaper unit.
