Changelog for 11/02/26
10/02/26 was re-released as 11/02/26 with an urgent patch (See below)
Added
Torque converter
- Added torque converter prefilling for much faster TCC engagement (More noticable with the zener board installed)
- Added override in TCU Settings for Torque converter max torque (Useful for those running custom torque converters)
Shifting
- Overhaul the crossover shifting algorithm
- New PID system for torque ramping (Self correcting for much smoother shifts)
- Auto-Flare recovery (For the common 3-4 flare)
- Manual modes (M/R) - Jump to overlap from first prefill stage (Much faster shift response time under high load without sacrificing comfort)
- Shaved 40ms off bleed shift phase (Slight shift latency reduction)
- Garage shift - Improve reaction speed and smoothness
Misc
- Added profile enable/disable for Tiptronic shifters with button profile selector
- Added profile save on end of drive for Tiptronic shifters with button profile selector
- Optional - Can also enable it for manual profiles too!
- Added PID Target input speed and turbine speed to `Shift algorithm` data logger
- EGS52 - Broadcast `FPC.AAD` signal (For Maybach)
- EGS52 Cars with SBC (W211) - Tell SBC to apply the brake when shifting to D for smoother garage shifting
- `Debug` - Allow the user to modify friction coefficients in TCU Settings
Fixes
- Fixed maths code that would occasionally cause an Integer underflow
- Fixed pressure manager not receiving target gear during shift (For pressure calculations)
- 11/02/26 - Fixed torque converter from re-locking during load downshifting when it was not supposed to
- 11/02/26 - Fixed very harsh upshifts being caused by wrong PID variable assignment from TCU Settings
NOTE: Race, Manual and Winter profiles are disabled by default now for the Tiptronic shifter. You can enable them in TCU Settings under `Shifter settings`
