HTG tuning GCU uses two step adaptation / calibration process for supported transmissions. First adaptation phase analyzes solenoid characteristics, second one depending on transmission type measures clutch characteristics and fork engagement points.
To fully and properly execute adaptation process follow steps below:
- Make sure GCU is connected and has valid configuration uploaded and saved.
- Valid configuration should have mandatory inputs assigned (and checked for proper reading) and gear ratios filled in.
- Make sure that battery is fully charged. It’s good to let engine run for couple minutes before starting adaptation to be sure battery charge is proper.
- Turn ignition ON. Engine has to be stopped.
- Select GCU – > Start output adaptation.
- First adaptation is now being performer. It usually takes around 60 seconds.
- Wait until “CALIBRATION in proggress” notification goes away.
- To start transmission (2nd) adaptation OUTPUT adaptation has to be done first!
- Start the engine and hold the brake. Vehicle’s wheels can not rotate during this step, neither the vehicle can move.
- Select GCU -> Start transmission adaptation.
- Second adaptation is now being performed. It takes 2-5 minutes.
- Wait until “CALIBRATION in proggress” notification goes away.
- Good to go. We suggest cycling D N R N D modes couple of times so GCU learns how to engage them in the first place and then perform drive using all the gears.
- Live adaptation is stored permanently while switching back to N or P.
Important: Without adaptation GCU may operate inaccurately or may not operate transmission at all!
IMPORTANT #2: Adaptation resets learned values so initial shifts may be delayed until GCU learns new values again.
HINTS :
- Make sure GCU uses HTG drivers (available on our website) in device manager of Your system, otherwise it might disconnect during adaptation
- First adaptation is most accurate with the transmission in operating temperature. You can redo first adaptation whenever you experience the need for it although it may slightly affect performance.
