Holley HP PMW Cooling Fan Control
Ok so I was reading on another post on here using the E67 for PWM fan control and the Vette #15-80803 controller and it got me thinking.
I am installing the Holley HP efi on a customer vehicle with a boosted LS7, and it has a single cooling fan.
Checking the outputs I am able to set up a -(low) PWM set to a fixed frequency or 128Hz. I set up a table using MAP and CTS for the x and y axis and table units with duty cycle so that the fan could ramp up for both temp and boost pressure.
Input triggers set at:
RPM activate above 450 (so will only come on with engine running)
Temp activate above 170 (so fan starts at 25% and will ramp up to 95% by 195)
VSS deactivate above 60 MPH
Any thoughts? I have not installed or attempted yet but appears it should work?
