T43 2010 can compatibility

[tonn0297]

Hello i have a 2010 t43 6l80 gearbox, and I want it to play nice with my 2017 e92a ecu.
Is this possible? I've looked far and wide, and I've seen you guys have decompile the t43 bin so I'm hoping I can make a Mashup of 2 t43 OS.. Is this viable ?

Currently it's kinda working, I get data and it can shift gears, but I get a u100 and u101 error..

The current tehcem is a 24254908, and I can gather data via HPT or buy a elm to upload the bin if needed

Kind regards Tonny Møller

Or if we can decompile all the CAN communication I can make a MCU that translates it all?

This needs fact checking; my understanding is the t43 can be 'write entire' with any os. Now, should that be true, your next challenge is to find an application where the tcm was paired with an e92. If there was such a pairing, that would be the os I would try.

Decomplication of the e92 can messages would need documentation that somebody somewhere has but unfortunately I don't have anything gen 5. You have probably read trecools and kidturbo's posts where they're going the other way, a 10 speed to a gen 4.

If option 1 is not working out, how are you with decompilation tools? If you get started I can point you to the addresses where the can data frames are created on the t43 side where you can start some of your research. But NFI on the e92 side. If you look early on in my t43 disassembly thread there is a tool to get the bins out of your HP tune.

Thank you for the insight, I think I read that the T43 had some hardware revisions that made later os fail to flash..
I have 0 trubble finding a 2017 OS for it, but I don't dare writing it in fear of bricking it..
I've read the segment swapper thread and maybe something can be cobbled together by looking at a 2017 OS CAN Id's and make the 2010 look after the same addresses?
I'll take a look about getting bins out of HP tunes, and upload them..
I'm not familiar with decompile tools but I don't mind giving it a whirl, I see the "universal patcher" have T43 defenitions allready so maybe I can use that?

Kind regards

I just downloaded the tool, very awesome work! it works beautifully, tho no support for HPT beta 5.1.xx, if you want i can upload a file from it? i doubt they have changed much..

ill tinker arround seeing if i can get it to compare the older TCM OS with a newer one

There's newer versions to work with newer tune files, I haven't come across a free one yet. The one I attached is a free one I found for v4.x tunes.

The can functions and address tables reside in the OS segment.

Thanks a bunch, I did not see, can it also convert back? Or shuld I get a obdx to flash bin back?

Is there some good data on the addresses? I may need to map in giehra

Was there something wrong with the direction your HP forum thread went? Seemed like you got some solid advice. Thinking this thread is about to cover already trodden ground.

The newest version converts back with some minor limitation.

There is not good data on the addresses publicly available unfortunately. However if you know the can id's e.g. $19D (for torque request) you can text search the os segment for them. Once found, the deep rabbit hole dives start.

i may be in luck that the Table seek have some of them, shuld allow me to find them

)
And i have a CANbus analyser, sp i may be able to see what the ECM is requesting and if the TCM sends a response.
Thanks for the pointers, ill probably ask a bunch more.. if i need to look at the raw BIN, what software wuld be prefered to get help if needed?
