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
