Is there any way to reprogram fan to come on at highway speeds.

 

I think my problem is aev bumper , winch , and lights are blocking to much of air flow?

 

The Flashpaq has an option to turn it on at lower engine temps. Don't know what the range is or if it would help you.

 

Depending on the tune, the Flashpaq adjusts the electric motor speeds accordingly; or you can modify it yourself.

Mine is currently set to turn the fan on low when the temp hits 195, medium at 210 and high speed at 220.

Even stock, the fan should be coming on at highway speeds if your coolant temperature is high enough. Is your needle going any further than straight up and down?

 

Yes it has . I am running a 6.1 hemi will flashpac work with that? I have heard that many with 6.1 hemi are having heat issues. Just trying different options.
