Well, now I’m really curious….
Years back I mocked up and bench tested a variable speed fan controller, using an arduino, and ECT signal.
Worked perfect on the bench, but car died before I could put it on the road…
So, what signal are you sending to it? Using arduino?
You probably have this all documented….
Edit:
Just found the thread you did, good stuff!
I may play with using an arduino to supply the pwm. This could be a feature rich, and easy setup, for cheap, lol.
Thanks for the info!
I started building an Arduino setup for it. Was going to install a separate ECT sensor at the rear of the intake and compensate for it running slightly cooler there in the programming.
About 50% done but stopped to focus on getting the car back in one piece. Was using this thread as a guide
