There is no way for now, you can only try reverse engineering.

Thats not right...
I have a dump with hex code
And on bitbox.ru you can get a programm to recalc the checksum.

It's true, yes you can read over obd. Yes you can read with bootmode, i already did that.
But there is no DAMOS/A2L or something, you just have the binary. I asked bitbox guys, they even can not modify it. Maybe only some simple values.
So you have to do reverse engineering on boot mode file to understand, what's doing.

You need a dude... he must read machine code and understand....
what simple values you know can change...
my idea is to put more pessure to the clutches and more pressure to the torque converter clutch

Does someone have a good transmission tune file.. i dont think
RE: How to tune transmission?! Bmw siemens gs20 - starshy - 06-06-2016
You can not pay, because no one ever has done this! As i said, do full readout in boot mode, i can prepare you file. Then go with IDA pro, and understand the Code, only takes some "month" to do that. This is where i stopped and converted to manual.
