Looking through some of my transmission tunes it seems like the "Gear Selector" is generally set to 10. In the one sticky by Steven he has one set to 29 (one of the manual modes).
Curious if anyone has seen a stock setting other than 10, and if they can share the tune and/or what vehicle it came with.
how does your OS utilize [TCM] 30598 ?
How can you tell?Quote:

you tell that by logging: <channel ParameterID="7" /> shift IDQuote:

adjusting the zf8 while not fully understanding what you are changing is a recipe for disaster!
if you dont want to pay for help i suggest you leave that trans alone
Haha. Shift ID is generally 5, with hard decel at 0, and steep hills at 10. Not that complicated. Manual mode would use table 27 that gets remapped to 5... basically in the ram 80% of the tables are remapped to 5 at some point anyways.Quote:

Well said bmagnan... some people in here are only for business and not to share knowledge.
Now, to your question:
Some applications will mostly default to Shift ID 5 to simplify the tune (specially if there is no other modes available - like sport, track, ... )
In case you want to do a test, change manual table to value either 27, 28 or 29. Change shift schedule accordingly. Give it a try.
Yea that's the goal, I'll do some tests and report back. I know for me when I enable ERS for instance, it calls out table 27, but then gets remapped to 5 (which also makes sense since ERS is a limiter routine and not directly paddle shift). Seems that I should be able to remove the remapping and keep it in table 27 to retain full paddle shifting (auto stick).Quote:

I know another member had said he did something similar as an early way to disable MDS.
What??? What is the goal???
And paddle shifting is not auto stick, sorry
Dodge refers to paddle shifting as tip tonic
Auto stick and tip tonic use completely different schedules
What exactly are you trying to do accomplish by changing the “gear selector” scalar?
Isnt Auto Stick Chryslers lingo more or less for manual shifting? Basically same thing as Tip Tronic like other Manufacturers call it. So if Auto Stick isn't for Manual control of the Auto Gearbox via paddles or Shift Stick, what is it?Quote:

For instance, his is set to 29, while mine was 10. To me, setting this value to something like 27 would cause the truck to default to one of the manual maps (or more importantly one of the non aggression maps). See below:

Map 27 and 28 are used for paddles/autostick, so by changing the shift pattern re-mapping you are able to get shift control instead of ERS too. For instance, my default Ram manual mapping is:
Attachment 156185
and 27 is remapped to 5... so when the buttons on the steering wheel are pressed, it calls to map 27, then just get's put right back to map 5 (with the addition of needing button presses to limit the upper gear)
However, other vehicles are set up with the following:
Attachment 156178
which can provide a much clearer overall picture of what's happening and the possible modes the transmission can support. For the Ram though, since it is a PNRD selector and not a PNRDM, there is no way we can get into the "M Gate" section... so that's why they have the same value across all 4 columns. In any event, it does provide valuable insights to the subtle differences in the shift modes between "M Gate" and "Tip Tronic"
By changing the re-mapping function in my vehicle we can allow the trans to have an actual upper limit set to prevent shifting unless another press of the + button is registered
Attachment 156182
As a note, there are different types of manual shifting. Map 27 is paddle shifting (Tip Tronic) and Map 28 is autostick (M Gate).
One of the things I hope to also accomplish in this new tune is to display the gear in the cluster, so my plan is to change the "Gear Selector" from 10 to 27 (for instance) and replace the map with the values from Shift ID 5, so it will think it's in manual mode and display the gear on the cluster, while still shifting like a normal transmission without the use of manual shifting. I'm not sure if map 27 is the true one I need to use, or if I should use 28, 29, 40, etc... but I'll report back once I have my solution.
No. A challenger is not made by BMW. Mopars lingo for auto stick is 'M-Gate'. That's what it is called when you click the console shifter over to the left and turn it into a ratchet shifter.Quote:

With M-Gate the thing will drive right into the limiter if you do not manually pull the lever (ratchet the shifter) before the rpm hits the engines redline.
This ^^^ is how it works as delivered. OEM.
With tuning it can be set up to do whatever you want it to do...
All you need to know is, 1) what you want it to do, and 2) what to change.
Part of that is knowing the names.
Glad i could be of assistance : )
trying to change what is being displayed on the cluster by changing the shift point for the transmission...Quote:

Other tuners have done it on other platforms (other than HP)… so I know there is a way. :)Quote:

The transmission OS sends some flag to the cluster to tell it to display the current gear… I just need to find out how to make it kick out that message.
i may be mistaken but i am 99% certain you will need to go into the BCM to get to where you want to go
For other platforms I think that may be true, but for Rams equipped with ERS they do not work with setting the BCM. It needs to happen through the transmission tune.Quote:

Yea, in the new Beta VCM Editor it is changeable now, so I think that should be all that has to be done. If not, I’ll check out that OS too. Thanks for the update!
The current released version is still read only…
Hey mike can you post up that stock 392 file you used? id like to check it out.Quote:
