    Transmission Cooler, AFE CAC and Tune Updates

    V10 Excursion Tranmission Cooler Only:

    Some of you may remember that I bought the Excursion V10 tranmission cooler and installed it, while removing the heat exchanger in the radiator end tank completely from the loop. I had been running it like this all summer with no ill effect and saw no temps above the usual 203F. The problem was I had not towed with it to really push the limits.

    I finally got a good trip with the travel trailer, 4.5 hours each way, and up some pretty solid hills. One was 2 miles of 9% grade at 65 mph. The tranmission fluid never got above 210F which is pretty typical for my truck while towing.



    So overall, I would say this mod was a success and I am hoping it took some load off the engine coolant.

    AFE Intercooler:

    I can't decide if this thing does much. I saw manifold temperatures in excess of 100F on a day that got no hotter than 65F. So basically a 40-50F temperature differential when under heavy load. I imagine on a 100F day ill be in the 150's or so. Not sure what other people get from their intercoolers but this isnt that great to me.

    "TMAP" in the above picture is my manifold temp.

    Gearhead Tow Tune:

    I know we have a lot of Gearhead fans here, and I run their tune daily, but this was my first experience with the tow tune where I actually exceeded 55mph and towed for more than 30 minutes. This was everything from 70 mph on I-15 going up and down some solid grades, to some 65 mph 2 lane roads, to 2 miles of 9% grade at 65mph, etc. All of this on was Chevron or P66 91 Octane fuel.

    I gotta be honest, the 5Star tune is better. Even my 87 Octane tune. The Gearhead tune just does not have the refined shifting and low end grunt of the 5Star. I often found myself approching hills and waiting what felt like an eternity for the transmission to downshift. I would lose speed and then it would go for the downshift. Using cruise control was obnoxious because it would slow down and speed up on every hill. Eventually I would just start preemptively downshifting it in preparation for a hill. Part of the issue was the lack of low end power that is inherent with the Gearhead tunes. It would try to hold the taller gear but it didnt have the balls. I guess if they lowered the downshift threshold it might feel better, but then it might not hold 6th on the freeway, I dont know.

    The good news was that the LOR was pretty much pegged at -1 the whole trip on the 91, only at the very end did it drop to -.8. KR's generally were in the negatives, especially under load.

    Excellent post.

    I'm taking notes from all of these towing and overheating threads for when we purchase a TT. The only significant tow I've done was in December, so there's no telling how my temps will do towing heavy in summer I guess. I already have the Wagner, which I hope will be a huge step in the right direction.

    Baaaaaaaaaaa

    From what I gather, the 2015+ trucks don’t seem to have as much trouble with overheating. I would imagine you might be in a pretty good spot with just the CAC.

    I hope you're right. There doesn't seem to be much documentation on how the little guy fairs though. When I have towed it did great. But it has always either been flat towing, or when it was through mountains cold weather.

    Maybe I missed it, but a few questions if you don't mind..

    1) What is the weight of your trailer?
    2) This is on the stock radiator?
    3) Is the excursion v10 tranny radiator the same as the larger radiator that was used in the middle-east market for the f150 which some folks have installed?

    Bummer Gearhead doesn't want to modify their tune at the low gears. I have been keeping up with that thread and it seems to be the biggest negative about that tune. Others have raved about the shifting, so I'm surprised you didn't like it (although you're not the only one.) I totally get what you mean though. My current stock tune really hangs in high gears before it realizes it should downshift. Annoying as HELL. I have to do it manually to maintain my speed uphill when pulling. I don't quite understand what the hesitation is about regarding increasing power in lower gears. Is there an increased likelyhood of damage to the motor? Can this only be done by increasing boost, which affects the entire RPM range?

    Thanks for the detailed followup with your setup! Definitely helps those of us that tow.

    The way Matt puts it is be believes in keeping it "soft" below 2500 rpms to protect the motor. I also wish his tune had more tip in.

    Im a tune junkie. I have GH auto adjust tunes and the BCB tunes. I prefer the BCB. Still tweaking it a little bit but I noticed the OAR is a lot more active on the BCB. It has more power for the daily driver one. The only thing I did not like is the 4-3 downshift was really rough. Casey fixed that and breaking in the new revision. So far I like it a lot more than the GH performance tune.

    I can't remember what year your truck is? I have the Gearhead tune and I like it. May try the BCB tune. Mine is a 2013.

    Im a 2013 as well. I like the GH tune. Just not enough for me and the shifting felt weird to me.

    Good to hear you've gotten good results.

    Too bad you can't get numbers over 85F. My truck does great below that temp, never breaks 230F ECT and tranny not over 210. Once ambient goes over 85F ambient is when I start getting up into the 240F range ECTs and 230F TFT's. Got the Saudi Arabia tranny cooler I'm going to try next year while keeping the stock radiator unit and see how it does.

    My scanner doesn't do IAT2, but I did run Forscan on a long pull once. In 100F ambient temp my IAT2 was about 165-170F with the stock I/C (+70F). (on the 8-mile 6-8% grade that usually kills my truck). From what I've read, you are supposed to be down within 10-20F of ambient with a good aftermarket unit.
