Programing Brushless Radiator Fan? 1990 Mazda Miata

[Noah Levreau]

I've been thinking about going to brushless radiator fan. To get it to work properly I would need PWM outputs. Would I need to use lua for it? Does anyone have any experience with using brushless radiator fans and programing it into the ecu or know how I can do so?

I am having a hard time finding info about it.

Thanks!

You could use GPPWM to control the fan pwm duty cycle based on coolant temp/engine rpm.

If you need more complex logic, lua is the place.

Okay. So this is a noob question, but for those tables is the load axis the temp or the pwm duty cycle? It looks like to be the temp, but I am not sure
