Changelog for 25/10/26

Added

  • New adaptation system for torque adaptations - 2D maps are used now for Load vs RPM, for a much more accurate adaptation result
  • Overhauled the torque converter control code
  • Auto-upshift when approaching redline RPM based on how long the next upshift should take (To avoid bouncing off the limiter when accelerating quickly) - This is enabled for all profiles except (R)ace mode, so (R)ace mode becomes true manual mode
  • New garage shift system - Should result in a far more smoother garage shift into R or D.
  • Added torque request support for HFM CAN Layer
  • Added air flow mass adaptation for HFM CAN Layer

Changed

  • (A)gility mode and (R)ace mode now have special shift logic to dramatically speed up gear changes (Derived from a mixture of Porsche and SLR firmware - along with some custom tweaks). This however is not compatible with adaptations, so adaptations are disabled when in these modes
  • Shift paddles and TipTronic selector +/- inputs are now registered at the start of the press, rather than when released. This speeds up perceived shift latency

Fixed

  • EGS51 CAN - Torque request calculations
  • EGS51 CAN - Factor in engine drag torque when calculation input torque
  • Multiple bugs fixed that could cause the TCU to crash when saving maps
  • Various hardenings against improper calibrations
