Best PWM controller for Thermofan

Post by pjr311 »

Hi all,
I would like to control the speed of my thermofan and rather than reinvent the wheel, I thought to ask if there is a OEM part that works well with Megasquirt 3..

How much current does your fan pull?

Through 20 amps Dorman 902-903 is proven/reliable. It is OE on many early 2000's Jeep vehicles.

There is also an affordable Hella 20amp SSR. https://www.delcity.net/store/Solid-Sta ... 7.h_809799
86 Rx-7, swapped to 2.3 ford turbo (BW EFR 6758), ms3/ms3x sequential fuel /waste spark, ls2 coils
88 Tbird 2.3t, Microsquirt Module (PIMP), TFI ignition
