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`
