OK, made some progress and I pretty much have a starter spreadsheet built out. Different model years may have different TP%s so it's important to note the year of your vehicle, tire size and gears. The trans tunes are based on mph not rpm so I'll help a handful of people get started by doing some tire/gear conversions of a modest trans tune. I'll need to set up a place where these can be stored and shared, while of course making sure a direct link is cool with the moderators.

hey jpop how about a sample for the 2008 jk 3.8L with 32" tires?
i've tried the sample shift schedule from jk_shift..worked ok but i feel it can
be fine tuned..on the advance tuning settings i saw there is a low shift schedule
any info on what the difference is? i left that controlled by superchips since
i had no info for a shift schedule for this. let me know...thanks

Hey Guys, remember I have a manual JK! I've gone through all this on my Dodge Ram, but only so much I can do here. I'm happy to help people out but I don't have specific model year data as TP% can be different as well as things are dependent on your gears and tire size.
Here's a link to a blank spreadsheet. There might be something I overlooked, but I think it's fairly solid. I'll host the files for a while until there is some sort of more permanent solution. Keep in mind that Superchips won't be hosting any of these as this is totally an end user customizable tune. If you have any updates you think are necessary, I'll do my best to make changes. Also, make sure to read the notes from Sil as he was a big help in making this whole thing happen, from the beta testing on the Ram, helping me find my way with my truck and getting us to a starting point here so some data can be shared.
Anyway, here the link, https://files.me.com/jpop/bzia9e

I just have factory 18 inch wheels/tires. No major additional weight, just a snow plow mount and some ballast in the back. I kind of figured it would just give people a starting point. I wasn't really looking to do a bunch of full bore blasts with it, just wanted to avoid some of those annoying shifts. My worry when I first added the software was where in the heck to even start from. I think I found somebody's (may have been yours JPop) from a Dodge product to at least get me started. Once I got a first run entered, it was really pretty easy to tweak it. I guess after all that I have taken from this forum in the past, it was the least I could do to give a little back. I will tell anyone who is annoyed by the 07-11 auto trans, this $40.00 upgrade is worth its weight in gold.

Here's a quick look at what's going on with the changes,
Full Stock and dstang schedules
1 up and 2 down are relatively close to stock holding gear a little longer at low throttle.
2 up 3 down has a moderately higher shift points and shorter stabs at the throttle for downshifting.

Here's a few more,
3 up 4 down will hold gear longer over stock with higher shift points to get rid of some low end bog. Some moderate jabs at the throttle for downshifts.
Overall better spacing between up shifts which will help to stay in the torque band.

and the rest of them.
Overall will down shift quicker with shorter jabs at the throttle.
Higher rpms to shift into OD and better spacing to keep torque and power up.

OK, I guess I need to clean this up, probably a lot, so people have a better understanding of what's going on. Nothing wrong with the schedule and the spreadsheet, I just need to do a better job of explaining what the benefits are.
For me, the advanced tran tune was the best improvement I ever made to my Dodge Ram. I clearly see that people have a much greater need here with an underpowered and often under geared vehicle. An opportunity to hold gear longer for heavier JKs with plus size tires, and better immediacy of downshifts so you don't need to bog down before it happens. Extremely powerful stuff, but only so much I can do without feedback.

This is needed because throttle percentages can change from year to year, and mph can change with tire size/gear ratio. If someone fills out just their stock values, I can help them build out a modest shift schedule.
Here is a link to the shift schedule spreadsheet done by d70stang.

I included this because the graphs in the spreadsheets give a visual reference of what's going on.
Again, I'll help a handful of people out with a starter schedule but I need their stock TP%s and MPHs to begin. Once a handful of them are done it will start coming together and with more input better shift schedules.
