I know noone who ever changed GS20 ecu, or has Damos or made Checksum. May be possible to find some maps, but still lot of reverse engineering to do. If you have any more Informations, feel free to share.

Sorry, i don't have any information to hell you. I thought i can get some information from the files above, but i didn't find any useful data to change the TCC usage...

have you tried to reflash with other bmw factory software.

I have put 5 series gearbox software to 3 series gearbox. 5 series wiill lock in less rmp than 3 series. car runs smoother and with less fuel in urban. I used Dis v44 to rewrite software.

[jodel]

Well, the 5 series locks up pretty Late, too. I want to lock it faster...

Hi Mate,

Any new for lowest sped lockup switch?

I'm looking for a solution too for e83 GS20 MS45 combo

[Cloudforce]

X83 already has the best torque converter lockup

[Vojnoo]

Maybe the best but not optimal....

I saw a solution for ZF (with Bosch ECU)to add an Alpina software, but not for this Siemens ECU :(

some idea, or solution?

Hi
I think I can help you with gs2.0 siemens TCC set points and shitpoints.
What tool did you use to read/write?

[Cloudforce]

Just read it with a PSOP44 flasher.
