Um, generally one does not want the fan controller to have the fan come on below the t-stat rating. Once the car is up to temp, the fan would never really shut off.
If running a 195/197 stat (193 is new to me), I guess I would have the low speed come on at ~210 and off at 202-ish. Have high speed come on at 220 or so.
This is where a 180 stat would really help with setting the fan up so you dont need to get so hot. A mech fan is always working, so you dont need that bufferzone with the fan temps vs the stat rating.
If it helps just for comparison, the 94-95 low speed fan comes on at 208*F, off at 200*F. High speed doesnt come on till 226. Now this is stupid, but gives an idea of a stock threshold (where emissions was a concern more than what is best for the motor).
A 180 stat would allow low speed to be ~195/187 (on/off, respectively) and you could set high speed whereever you want above that (on at 205-208, etc).
I have not used either of those products, so take this as my crude, general two cents.
Good luck.
