Thanks for the info. Next time you tow please keep an eye on the coolant temps and report back. I'm really liking the temps you posted. It was 109 in S. Texas today and my truck sounded like a damn jet, my electric fans were spinning so fast!!

Ever data log that tune? If so how does everything look good?

Honestly man. You are overthinking the whole thermostat thing. Try it, if it's not what you thought move on. It's a $40 investment. I feel as if you'll like the benefit of cooler temps IMO

Thanks blue5.0, I do have a 170 t-stat and have used it. I do like the cooler temps, you sir are right. I was curious about the 170 vs people running the stock one and how it does too as far as tuning goes. I was kinda told it was a must for running tunes, but i now think it depends on how heavy modded one might be and how aggressive the tuning is. Just looking for peoples feedback. I have had some gear heads say that running a cooler one may actually hurt more than help on the warm up conditions. Some say the cats are affected. I would say people out west in more extreme conditions would definitely benefit more with tuning and fan settings. especially a ecoboost. I have tunes set up for both, the stock most recent being. That is why i started this thread and the data log thread to see how much or many even do it or use it to their benefit. Towing will definitely make a difference. Just trying to learn a little more about those 2 topics. thanks again for you contributions too, I hope I haven't got on anyones nerves.

Gotcha. Definitely not on my nerves. These are great topics. I just thought you were nervous on pulling the trigger on a $40 part that takes a few minutes to install. I've been really happy this summer, being the first summer with the 170* t-stat. I haven't seen temps above 191*. Even when it has been 97-98*

I monitored coolant and cat temperatures yesterday (unloaded) while at 91* ambient temp. Idling at a light and slow city driving, I saw ~ 1000* at the cats and a max of 1400* on the highway at 65 mph. My coolant temp remained consistent at 183* (a/c on); only fluctuating a couple of degrees cooler at one time. I never really monitored the cat temps too much before, but I want to say they might be ~100* or so cooler. Don't hold me to that though.

Thanks for that information. I have a x4 is that how you checked yours? Or using the live link with laptop choosing that PID? This is really a good way to see if their is a real difference on the cats. thank you sir. If your a/c was on then the fans run more too because of that, but your coolant temp was consistent holding at 183*

I was using a Bluetooth dongle and android Torque Pro app on my phone. I have Torque Pro, ForScan, and Auto Enginuity on my laptop, as well. I could data log with any of these, but use my phone for a convenient way to monitor live parameters. I keep the dongle in the little cubby in the dash.

I am due to get myself a smart phone, Is the android more user friendly than say a I-phone? As far as the Torque Pro app goes?

redneck wrencher

I have never had an I-phone, so I can't vouch for that. I haven't really had any issues with the android operating system on my Samsung phones, in general or with the app. I recently added a companion to the app that allows it to alert to spark knock and degree of timing retard when it occurs. The 5 Star tune seems to working well to keep my timing within safe, but efficient, limits for my chosen octane rating. When I get a chance, I am going to try some 89 octane fuel and see how it plays with the current tuning.
