Working car status? Better fix that.
Time to fix something that wasn't broke.
Out with the old
In with the new
Proof of concept
Goal is to make a soft start cooling fan setup. Replacing the old mechanical relays with new solid state relays which allow for PWM driving. Still playing with the driving frequency ( you can hear that grind noise in video of fan not liking the low frequency) Currently just using a TPS vs RPM 2D table with duty cycle filling it.
End goal will be a slow soft start as engine temps rise, versus the old sudden fan on current inrush.
Holley is very cool stuff for those of us who can't leave anything alone.
