Hi guys. The last few months I have been disassembling the TC-SST firmware. Here's what I found:
S-Sport enable on Ralliart
Gears ratio
Shifting tables
REV limiter
Disable cold engine long shifts
Shifts depends on vehicle tilt angle (only for normal mode) and coolant temperature (cold shift request). As example, we're on Normal mode and tilt angle is 0 degrees => 4th shift row will be used.
TC-SST has 3 independent calibration areas (for DOM/EU/NAS destination). It can be changed by variant coding of TC-SST.
Also, the TC-SST flasher was developed for reading and writing ROM. ​​​​​
Here is example of one table:
<scaling name="Acc Pedal Pos %" units="%" toexpr="x" frexpr="x" format="%.0f" min="0" max="100" inc="1" storagetype="uint8" endian="little"/>
<scaling name="Shift Row" units="row" toexpr="x/16" frexpr="x*16" format="%.0f" min="0" max="8" inc="1" storagetype="uint8" endian="little"/>
<scaling name="Speed" units="km/h" toexpr="x/64" frexpr="x*64" format="%.0f" min="0" max="300" inc="1" storagetype="uint16" endian="little"/>
<table name="DOM - Shifting 1st to 2nd" category="Shifting" address="24c84" type="3D" level="1" swapxy="true" scaling="Speed">
<table name="Accelerator Pedal Position" address="252d8" type="X Axis" elements="10" scaling="Acc Pedal Pos %"/>
<table name="Shift Row" address="2539c" type="Y Axis" elements="8" scaling="Shift Row"/>
</table>

 

Very cool!

Have you found clamp pressure/solenoid pressure tables and shift response tables yet?

Also torque limit tables.

All those where key when found for VW DSG

 

Following!

 

Pressure depends on torque data received from Engine ECU, but has some increase/decrease coefficients, searching in progress.
About tq limit i have found only one table for a while.
Below 2 tables what i talking about. Tq subtractor from SST and torque data from engine ECU.

 

Also i have patched sst rom to add "mode23" for RAM readings by replacing function 17
On a picture readings of internal milliseconds timer and piece of injected code

Very cool, finally someone cracks this. Only took over a decade lol.

How about shift speed? That is another thing that really changes how the transmission feels. I’ve been tuning that a lot with my dsg and it’s a science to get right. Lots of road testing and logging

 

Still in search...

 

Great scott! The crazy EVO community is still hacking this rolling computer... Fantastic.

 

Def file is out now

ask kolyandex

actually possible

 

TC-SST flasher and xml defs available
iam@kolyandex.su

 

How does your work compare to what EvoScan site has just released for the SST?

 

This roms based on my xml.

 

I did it on my Evo X MR!
I changed S-Sport delay and minimum speed, and the "Shifting Row" for Sport and S-Sport (shifting speed points in auto mode)
Flashing process was very smooth, fast, no worries at all.
Nice work Kolyandex !
