I upgraded my Charger R/T cooling from single to dual fans, thicker radiator, oil cooler, and from 203?F thermostat to a 180?F.
A tuner reduced the e-fan settings by 22?F (226 to @205?F) but for the Low Speeds he reduced them by 32?F (217 to 185?F).
So I wanted to test the high speed and after getting it up to operating temp I had to put a blanket over the grill to get it to go higher then 196?F idling and the fans came on high speed at 201?F according to SRT pages instrumentation.
As soon as I removed the blanket they went back to low speed. It never raised above 201?F.
Now with a 37.4?F Hysteresis I was not expecting it to react so quickly. I dropped the blanket and looked at the gauge and it was @199?F.
I'm new to dialing in e-fans according to t-stat opening temps. Any help or guidance, links to said would be great.
Thanks
