Electric radiator fan temp control

[tnctx02]

Trying to find a way to change the temp when the electric cooling fan comes on in my 2017 Ram 1500 3.6L pentastar.
Does anyone know if this can be done with Alfa OBD?
If so, can you please point me in the right direction to change it?
Thanks in advance for any help!

That sure would be great, if that were an available option with AlfaOBD, but no.

The only way to accomplish this electronically is with an unlocked PCM and a tune.

If you search the threads, you will find discussions on this topic.

HP Tuner is the current preference.

V6 electric fan/180 t-stat tuning questions.

Next weekend I'll be installing a V6 fan (removing the clutch fan) and installing a 180 t-stat. I have some questions on tuning that I can't quite wrap my head around. I've talked to @Mojo88, searched here, AND on the HPtuners forums. It appears (screenshot) that I don't have a PWM fan, but a...

@Mojo88 has experience with this tweak using HP Tuner.

AlfaOBD won't do it.

To change the temp for the fan, you will need a tuner, or something similar that can change the PCM / ECM programming.
Your truck is a '17 and will need an unlocked ECM also, which is usually done by vendors like DiabloSport or HPTuners. Not for skinny wallets.

LOL. You hit send button while I was typing.

Thank you all for your responses.
After reading these, I have been looking at removing the fan and adding an aftermarket dual fan set up that I can set my own temps on.
Still investigating them.

Thanks again

You'll get codes if you remove the electric fan. If you're gonna do that,look into doing stand alone pusher fans in front of the rad,and leave the stock electric fan hooked up

Thanks for the idea! That makes much more sense.

There is a very experienced tuner not far from where I live I just found out about. Great reviews and has and can tune most anything, and he has his own dyno also.

He said he will unlock my truck, set my cooling fan temps however I want, will change the fan on settings for when the A/C is on, do some torque management settings, and a few other settings, and pretty much anything I want.

Also going to change the cold start 1500-1600 rpm immediate scream so that it will start at a lower rpm and creep up, then down.

The price is $600.00 all in. This way no taking the PCM out and sending it off, then buying Alpha OBD II, and me poking around not knowing what I'm doing.

This sounds more like the easy way out with the best results. What do those in the know think about this route?

If you go that far just buy HP tuners at that point. You dont need to be a tuner to set the fans, temps and idle.

Sounds like he's using HP if he does that. Its only 250 $ to Unluck an ECU straight from HP. Heck some places only charge 100$ now for that service now.

600$ is steep just to set a few setting that take 10 minutes...lol... Thats the price a full tune.

That was a most likely a complete tune price. It was just mentioned, we didn't go into a lot of detail. What I want may be less than that. He does seem to be well versed with the Pentastar engine, which is very important to me.

There are a few other things I want changed up also.

Anyway, I will go into more detail with him in a few weeks and get a firm price. I don't want to send my parts off in the mail to someone in another state, hoping they arrive back home safe, if at all. I don't care to buy the software and bypass cables needed for a one time use.

Years ago, I would tackle this myself with no second thoughts. Today, I hurt 24 hours a day, can barely get around some days, have a hard time getting up when I have to lay on the ground, don't sleep, which means I can't think well some days, ect....

My wife's car is the easiest thing to change oil on. I did it last week and it wore me completely out.

I'm old, arthritic, have muscle pain, don't sleep, and have a damaged heart from a heart attack.

Spending an extra 200-300 dollars to keep from hurting myself and possibly messing my PCM up is well worth it to me at this point.

A few years ago my thought process was completely different, but circumstances change in life....
