HTG GCU 1.1.2 change log
THIS IS OUTDATED FIRMWARE. CHECK SUPPORT PAGE FOR LATEST RELEASE!
Overview #
REQUIRED STEPS: as always – install latest HTG SUITE, connect to GCU (Shift + C), download config from GCU (Shift + D), send to GCU (Shift + S). This procedure updates config to latest version. Now go to GCU tab -> LOADER and upload latest firmware-1.1.2.
Dual Clutches: OUTPUT and STATIC adaptations have to be redone. DYNAMIC adaptation has to be redone as well including CL take-up learning
8HP: no changes to adaptation but since TORQUE model has been updated it might be needed to ERASE dynamic adaptation.
TORQUE MODEL v2 has been updated to V3. Please pay attention to fill necessary information and check torque reading for real values. MIN and MAX gear definition added in the general settings so pay attention to this as well – otherwise GCU will use only gear 1 🙂 Set parameter and enjoy all (or limited) gears.
See Dual Clutch learning procedure article TUNING / CLOSED LOOP / DC learning
