The TCU has the feature of setting up to 4 different Maps for the transmission. This can be normal Automatic mode, Towing Mode, Tiptronic Mode, Racing Mode, low range mode etc. Should a TCU start with the wrong selection due to pre setup, you may select 1 Map and first set the TCU up with all calibrations. Then select the 2 Map Buttons or 4 Map Switch selections and load the relevant Maps in them.

1 Map
This is for standard cars where the driver only need automatic mode.

2 Map buttons
This mode has 2 Maps and require the Tiptronic buttons to be installed. Pressing the Down button for 2 seconds will switch to Map number 2. Pressing the Up button for 2 seconds will switch to Map back to number 1. Note that the software will disconnect and then reconnect. It may take a couple of seconds. This is to read the new data from flash memory in the TCU. The TCU will do this in less than a second though. It can be done while driving. Also note that the TCU will default to Map 1 on startup.

4 Map Switch
This mode requires a rotary 4 Map switch to be installed on the TCU. Each position will activate the relevant Map to be used. Note that Map 1 and 2 may be changed while driving also 3 and 4. But 2 to 3 or 3 to 2 must be stationary. Should you switch to them while driving, nothing will happen until the speed is 0 km/h. Note that the TCU will start in the Map where the switch is positioned. This switch must be calibrated to suit different styles and versions of the Map selection switch. Note that this calibration is always in mode one and is saved in the TCU. Loading other maps will not alter the calibration. If this button is not available, it is either Pre Ver 3.2 firmware or the TCU is currently on a Map greater than 1. In the last case click on 1 Map do the calibration and then click on 4 Map Switch before you save the data to TCU. The older versions were preprogrammed and could not be changed.

Click on this button to enter calibration mode.

Put the Map switch in position 1. As a test you can go through all the positions to position 4 to see if the real time value change significantly.

Put the Map switch in position 1 and click on 1. It will become green. Go through the other positions 2, 3 & 4. Put the map switch in position 1 again and click Save & Close. Put the Switch selection to 4 Map Switch again. Then click to make the calibration permanent.

Note that the other Maps may not have data in and then the software will indicate Setup data could not be read. In this case click on Cancel and load a map into that Map memory.
