Is there a certain ambient temperature or combination of sernerios with temperature when the fan says on all the time while driving?

I noticed today that my fan stayed on 95 percent of the time while driving? Not hi but noticeable?

Thx

 

Absolutely


Fan speed is determined by the following


ECT
EOT
TFT
MPH
Ambeint temp
AC

 

That's as clear as mud

 

And how is that related to fanvar? Noticed that the fanvar changes value rapidly but the noise from the fan doesn't correlate to the number displayed - can be quiet at 100 and really loud when 40 or 50
Confusing me and I couldn't find anything about it with a quick search...

 

At 100% fanvar, if I recall, the fan will be at or above rpm. So, you will need to be watching all three pids to tell what is going on at what times .

 

Haha I know

I know pretty we'll how my truck is programmed idk if diffrent flashes change things so I didn't want to give misleading info

Some of my truck
95* ambient
35mph
218* ECT
AC alone kicked it to 500-800 range

There's more but I have to find where I posted it 3-4 years ago

 

That's what I assume but it doesn't seem to be quite like that - maybe forscan is not reading it correctly because I've been in a couple of jams this week and the fan works perfectly while fanvar hops around. I'll have to connect up the tuner and get a second opinion...

 

Mine will kick on in traffic when my Ect hits 208 or when at 206 and taking off from a stop light after it has ramped up once at 208. It drops down to 202 or 204 depending. At speed it will then only ramp up when I hit 208. Can't say the percent but I can hear it (probably along with everybody around) haven't looked at other parameters but as long as I here it is know it's working I'm OK with that.
