If You’re using any kind of a dual clutch transmission (GS7, PDK, DSG, etc) you’re going to need to do the adaptation before tuning the gearbox.
This procedure requires You to follow below steps:
- Start the engine
- Hold the brake during adaptation process
- Press “Run Adaptation” in the HTG Configuration App
- Gearbox will perform various actions allowing GCU to learn unique transmission’s calibration details. You will hear the selectors moving.
- After some time (up to 2 minutes) you will get information that the calibration has been finished.
- Successful adaptation will allow You to start tuning Your transmission from now on.
Pro tips:
Speed of the adaptation depends on the line pressure of the gearbox. Temporary lowering “Line Pressure” table (setting maximal line pressure (value 0%) in the idle range of the map) will speed-up whole process. Once adaptation is successful restore desired line pressure values.
Probable issue: Adaptation never finishes!
It means that adaptation process failed. You may consider that adaptation failed if it takes more than 3 minutes. There are three possible reasons causing such situation:
- Air not bled in transmission control system. To bleed the air retry adaptation procedure 2-3 times.
How to retry adaptation procedure?
Reset GCU by cutting off the power to the GCU (remember to remove USB cable as well), restart configuration app and retry adaptation process. - If it still fails, check Line Pressure, oil level – if there is still not enough oil in the gearbox selectors won’t have sufficient “power” to move .
- If the oil level is OK and line pressure is set to the max (value = 0%) it means that there is a electrical/mechanical issue most probably. Perform Valve Tester, check wiring and if You cannot find the issue – contact us. We will help You with full gearbox/wiring diagnostics.
