My mistake. Though the fan switch was on the outlet. Inlet (if in a single cooler) is same as pan. Pretty close anyway.

Like to see them sell different temp sensors. I mean it is super small and is has a small single threaded post that just hand tight into the inline an block.
Did you ever do a thermostat mod and what temps are you running? I know your setup is different and goal is mpg. Just been asking everyone that question lately.

Blue line is with the 180 F stat and the orange a 170 F stat. 55 mph is the constant. Air temp the variable.

Grumpy bear I may have asked you this before but I speak to so many people daily I get lost. Have you used or played with at all the Blue cat trans software. It is free and very very interesting. I'm trying to master these new trans. I am good at shifts and the adapt tables. But I know there is much more there. Also the rpm or the mph for shift points, lock up the TCC(torque convert clutch) in shifts. Up and down shift pressures. I think there can be huge improvements in mpg by setting the x pattern ,that is the normal drive gear to easy going. Then the tow haul more agressive. Also there is a special that says go to M6 and the tap up.and down quick shift. Maybe fun.
Got the software set now for 2 step. Just had to block out the misfire code under 3100rpm. Also dont know why I didn't remember this but the hill assist I need to be carefull of in tow haul.
Temps at Iran sit at 163* after many miles and not moving it can make it to 180* but fan will bring it back. Still haven't added the air dam. I know I need to just busy summer life.
Thinking if this is the case I will lower the HOT trans value to 200* vs stock 212* so if it hits 200* the trans goes into protection.

I don't tune. There are people way better than I. Not that I wouldn't like to learn. I gave up tuning when the brain was removed from the driver and put under the dash. Okay I tune I just don't do it via the ECU or TCM. I manipulate what it sees and let it do what it does. For instance. When I bought my TC88 in 05 I could have bought the Harley Race Tuner for a few hundred then paid for seat time on the dyno. Instead I read the files, installed twin coolers, which is desperately needed, which lowered the cylinder head temperature below the fully warmed up lean fuel table and it just increased the map 5% all by itself. Raised the fuel economy about 3 mpg, rid it of a decal pop and gained about 6 hp. manipulating the temp map with a cooler. I got a loaner tuner read from one of the guys at the shop that bet me I couldn't and I won that bet. 

 

You should see my 90 year old Dad with a paper clip, a low ohm ten turn pot and jumper play that tune.

Looks like you got the trans cooler mounted in a good spot, should be out of the way of road debris. I was gonna say maybe add some screen in front of it, but that doesn't look to be necessary now. Otherwise sounds like you're well on your way

 

Engine cover looks sweet, I just did that myself. Neat how a minor thing can spruce things up. Other members have used Chevy/GMC emblems off crossover engine covers, that's something to consider. That and if you don't want the Caddy emblem I'll take it off your hands :D

Haven't spent the time to track down a emblem I like yet.

Great build man, very informative. I don’t understand why all these kits or manifolds I see put the turbo where they do. The need to push it further into the front corner of the engine compartment. Create some separation for the heat. Armageddon did it right but I am not paying that. I will be welding my own together and I don’t think twins are necessary at all. Thank you for posting this learning a lot reading your stuff.

      OCI, not when but why?

      By Atlas · Posted

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.

      Will not stay in Reverse

      By TheGeek · Posted

      I have a LTZ and it has the shifter in the console, which I like, but, every now and then, it will not stay in Reverse. I go through all the motions, hold the button in, push the shifter forward and watch the dash.  The big red R comes on and also the back up camera.  Then, it just pops out of Reverse with the shifter all the way forward.  So then the game begins.  Back and to Drive, Reverse.  This goes on 8 - 10 times. Very frustrating. Had it back to the dealer and they replaced some kind of computer, but it is now happing again. It is so bad, my wife will not drive the truck, she is afraid of being stuck somewhere.    Anyone else with this PIA problem?

      I see where you’re going and I can appreciate that. Statistics can be misleading because of the word average. They say statistics show the average cost of a new vehicle is about 50k. The average monthly payment is close to 1000 dollars a month. That’s statistics for you. I know very few people who pay that.
