USE ANY POPULAR PWM FAN WITH ANY EXISTING TEMP SENSOR!
The FPM is a revolution in e-fan control. Instead of a dozen configuration switches and a pile of mind-numbing sensor charts, you “teach” the FPM your temperature setpoints using your running engine and two buttons. Four simple DIP switches set your fan's PWM frequency and polarity, covering all the most popular brushless fans and pumps. Because it learns your temperature curve, the FPM can work with any ECT sensor or gauge sensor you happen to have, OEM or aftermarket, PTC or NTC. In case you need 100% fan only at an overheat temperature, you can teach the FPM the “normal maximum” and then scale back the fan speed up to 20% using the third button. There's also an override pin that can connect directly to the AC clutch, to either force full speed or increase speed 50% whenever the compressor runs. Like all WM products it's hardy enough to live on top of the fan, and it's IP66 weatherproof if you seal the DIP switches with a dab of RTV. There's nothing else quite like it!

IMPORTANT NOTE FOR GM PCM's AND LS CONVERSIONS

E38 and some other popular GM PCM's may require a separate sensor for the FPM due to the way the PCM runs the sensor circuit. When using the OE ECT sensor for your temperature signal, if after installation the fan turns on or cycles continuously during cold starts until the engine reaches the set temperature, this is caused by the PCM and not the FPM. There is no workaround for this issue, a separate sensor dedicated to the FPM is the only good fix.
