Shift Scheduling HPtuners | HPtuner Shift Points | Hummer H3

Thanks I actually just asked about this in one of your later videos…. So disregard that last question I just asked to soon …. Oh and thanks for the h3 content it’s been appreciated

[@H3Humper]

Hello Rusty! I apologize, I thought I had responded to your comment but I don't see it! I am happy to know you've appreciated the H3 content so far, and thank you for sharing. Adjusting shift points to help transmission behavior while driving through the mountains is such a major benefit of HP Tuners! It is a powerful tool, and I definitely recommend getting familiar with it. What part of the world do you live?

Exactly what I was looking for

Happy you can across the video 🤓 Thanks for sharing!

[@crtinkering7323]

Nice video!! Stepping up your game I see!! Good job man!

[@H3Humper]

Hey man, I appreciate it! My gf's engine seized, so she's been daily driving the H3. Since I haven't been able to work on it, I figured tuning videos will work for the time being haha

[@rizkybiss]

Very nice. Did you have problems with it shifting hard? Like 1st to second? 🤔

[@H3Humper]

I often perceive the jolting of auto transmissions as being too hard! Not sure if it's any rougher than the other gears, though. In 4-low, 1st to 2nd feels like I have a turbo haha. Does your 1st to 2nd feel noticeably rough?

[@rizkybiss]

@@H3Humper it's intermittent. Sometimes it shifts smooth and sometimes you could kind of feel the shift a little more..... it's been fully rebuilt twice. I'm starting to think that's just the way it is....

[@H3Humper]

@@rizkybiss Interesting! I'll have to pay attention to mine a bit more to see if I experience something similar

[@semperfizo4811]

What shift points do you recommend for 35 inch tires?

[@trailtooth1447]

Very interested in this topic. But Hard to see what you are doing, even on a big screen…..need to redo this video.

[@H3Humper]

Happy to know you're interested,, and I appreciate your feedback 🤓 I apologize for the viewing difficulty! I will certainly make sure the tuning stuff is easier to see in upcoming videos. Thanks!

Curious what settings you finalized with. I'm running a Hypertech on my 08 3.7 and I went with +200 on the shift points and +500 on the rev limiter, and adjusted the transmission firmness to 50%.

[@H3Humper]

I hadn't looked into Hypertech too much until reading your comment, and the system looks sweet! Are you able to make changes while you're driving? For mine, I lowered my speed shift points to try lessening my engine RPM and improve MPG. I haven't actually changed mine in a while, though, so I can't recall in detail. I will look at my tune file tomorrow and let you know 🤓 I haven't played with shift firmness yet. Did your adjustment to 50% bring firmness up or down?

[@svxr8dr]

@@H3Humper Road Tuning is not doable with the Hypertech unfortunately. shift firmness was increased when I went to 50%. really enjoy the channel and looking forward to more!
