This is the normal mode for your vehicle where you will use it every day like town and open country driving. This mode is used with Tiptronic in Automatic selection. The buttons will merely tell the TCU which is the highest gear to use. It will down shift if it is permitted. If you selected Maximum gear to be 3 for example, then it will ride automatic up to third gear. Up and down shifts will commence as usual.
This mode can also be slightly changed as a Towing mode where you require the engine to shift at higher RPM’s and do downshifts quicker to keep the engine in the torque band. This will be called Towing Map and saved in another Map position. Usually map 2 because map 1 and map2 can be changed on the fly. Map 2 to 3 or 3 to 2 must be changed at stand still.
Another variation is Sport map where you also select gears at higher RPM’s to make the engine more responsive. Very much like the Towing map.

Procedure of Tuning.

Use this guide if you don’t know the final drive ratio or wheel sizes so that you can use the Tyre calculator. (Wheel sizes is written on the sidewalls like 225/55/17)

Standing Still

1. First go through the setup and enter all the relevant settings that you do know.
2. Calibrate the TPS sensor.
3. Start the engine and check the rev counter calibration is correct, then save the data and switch the engine off.
4. Switch the ignition on and do the following settings while you are standing still.
5. Start with the following option settings.

Set the Gear-Down Speed to zero and the Kick-Down Speed to 200 for all the gear profiles as below.

Set the Gear-Up Speed for first gear to 100 as in the block below.

This will disable the speed settings so that you can set the RPM settings first. It will not work for Tiptronic as you do need the required speed settings.

Top Dots
Then set the Up Shift (Blue Line) High Dot to 90% TPS value, and to the maximum RPM value allowed for that gear. Do this for each gear. Set Gear 1 a bit lower to compensate for the shift time of the transmission. If it is too high the engine will over-rev.
Now set the Down Shift (Red Line) High Dot to 90% TPS value and half of the maximum RPM value allowed for that gear. Do this for each gear. An example is, if you want a gear to reach 6000RPM under WOT, adjust the Down Shift High Dot to 3000RPM. This will be a safe value to start with, so that shift down does not over-rev the engine.

Bottom Dots
Set the Up Shift (Blue Line) Low Dot to idle RPM plus 800 RPM. An example is if idle RPM is 800, set this Dot to 1600RPM. Do this for each gear and add 100RPM to the next gear.
Now set the Down Shift (Red Line) Low Dot to idle RPM plus 200 RPM. An example is if idle RPM is 800, set this Dot to 1000RPM. Do this for each gear again adding 100RPM per gear. This will ensure that the gear does shift back when idling RPM is reached.

Middle Dots
Then set the Up Shift (Blue Line) Middle Dot to 40% TPS value, and set the RPM value slightly right form a straight line between the Low and High Dot. Do this for each gear.
Now set the Down Shift (Red Line) Middle Dot to 40% TPS value, and set the RPM value slightly right form a straight line between the Low and High Dot. Do this for each
Preparation is now done and the gearbox should shift and make the vehicle drivable. Save this to the TCU.

Driving and Basic Settings
Start the engine and pull off in drive. Find a quiet level road and calibrate the speedometer.

Should the transmission at any time feel like slipping, immediately back off the throttle and decrease the line pressure graph at that TPS setting. (It is the blue graph 1.) These clutches are small and will burn quickly and also burn the oil. If the transmission has more than one control solenoid, see the specific instructions on how to adjust the different graphs. Note, lowering the blue line pressure graph will increase line pressure that will result in a firmer shift. This may be transmission specific so make sure you have the special instructions document handy.

The first setting to adjust is light throttle pull off. Push the throttle to about 5 to 10 % TPS value and feel each gear when it shifts forward. This is an important setting if you crawl in traffic. If it shifts too quick to your liking, move the Up Shift (Blue Line) Low Dot more to the right and vice versa. Do this for each gear.

The next setting to adjust is low throttle gear down. For this setting we use the Gear-Down Speed setting. It is better to use actual road speed for gear down than RPM’s. The reason is that torque converter’s slip gives a false sense of drivetrain RPM’s at low engine RPM’s. This is due to the stall speed of the torque converter. There is also a difference in RPM when the Torque Converter Clutch is engage or not. Another reason is lower gears sometimes have free-wheel clutches which means the engine will idle ate high speeds. First you need to set the Down Shift (Red Line) Low Dot to idle RPM minus 200 RPM. An example is if idle RPM is 800, set this Dot to 600RPM. Do this for each gear. This will prevent the TCU to gear down by engine RPM’s.

Enter a value for the Gear Down Speed settings for all the gears except Gear 1. Leave it at 100 Km/h. Use a value which you thing it should gear down. Start with a lower value to prevent lockup of the wheels.

Now accelerate to top gear and release the throttle. Now feel each gear when it shifts back. If it shifts back harsh or too quickly, decrease the value and vice versa. Do this for each gear.

The Gear-Up Speed setting in Gear 1 is used as a forward shift speed to second gear. This is handy when the vehicle starts rolling on a downhill where the driver does not touch the throttle. When the vehicle exceeds this speed, the TCU will automatically shift to second gear. This speed must be higher than the second gear, Gear-Down Speed setting, otherwise the transmission will hunt between the gears. On some transmissions this setting is important as 1st and 2nd gear has a free running clutch and no engine brake, which means that RPM stay at idle regardless of the speed of the vehicle. Start with a value of 10km/h and make gear 2 Gear down speed 8.

Middle Blue Dots
To set the Up Shift (Blue Line) Middle Dot, press the throttle in about 40% TPS value. Again, feel each shift if it takes place at the right RPM’s. If it shifts too quickly move the Dot more to the right and vice versa. Do this for each gear.

Top Red Dots
Now to set the Down Shift (Red Line) High Dot RPM value, you need to cruise in the gears higher than gear 1, and at an RPM just lower than this Dot value. Then kick the throttle in quickly to reach a value higher than 90% TPS value. When the TCU shifts the previous gear, feel if the RPM in this gear is too high or too low. Adjust the Dot only left or right. This kick back should occur at a RPM where the lower gear still has range to improve the vehicle speed, without over-revving the engine. It should not be too low so that the engine labors in higher gear and not be able to gear down under high load conditions. Do this for each gear.

Middle Red Dots
To set the Down Shift (Red Line) Middle Dot for gear down when Throttle is pressed is a bit trickier. You’ll need to cruise in each gear at low RPM. Then press the throttle in at certain depths and feel as gear down occurs at the correct acceleration. Adjust this Dot left and right till kickback occurs at the correct throttle opening.

Kick Down Speed
The last shift setting to adjust is the Kick-Down Speed setting. This setting lets the TCU gear down regardless of the RPM or if the Gear Shift Time has lapsed. It will also let the TCU shift back 2 gears at once. The TCU will gear down when the speed is below this value and the throttle is pressed to a TPS value greater than the Down Shift (Red Line) High Dot TPS value. This is set at 90% TPS. To start with a reasonable value, use 50% of the maximum speed for the lower gear. Example: If Gear 2 can reach a speed of 100 Km/h, use 50Km/h as a setting for Gear 3. This will leave ample room for the lower gear to accelerate the vehicle. If you found that the engine revs in the lower gear is too low, increase this value. Do this for all the gears except Gear 1.

Gear Shift Time is important to let the transmission complete its hydraulic action before the TCU attempts its next shift. A setting here is normally 2.5 to 3 seconds. If the time is too short the TCU will do calculations for the next gear while the transmission has not yet engaged that gear. This will result in the transmission skipping gears and the engine revs falling too low. It will then kickback and start an erratic shift process. Rather start with a larger value and decrease till you detect inadequate operation. Then increase the time slightly. Also note that during the shift time at full throttle the engine may over-rev. then decrease the blue top dot’s RPM value.

Now, drive around with the vehicle under normal city and highway conditions feeling the TCU operation. This will indicate where little adjustment may be required to get the shifting to perfection.

Save the profile in the TCU and also on the PC as Profile 1 Automatic.Spitcu.

Now, select Profile 2 and load the file Profile 1 Automatic. Spitcu from the PC into the TCU. Press Connect and save it to the flash in the TCU and then start editing from there.

Repeat the save process and go to the next profile. For low range you may need to start over as with Profile 1. This is due to the speed settings that will be different. If the tranny has a L/R switch, then wire it in or make yourself a L/R profile. Then use only that profile with low range.

Once you are familiar with tuning you may tune the middle and top dots also in the up and down dimension. This is mostly a feeling by yourself if the transmission does what you want it to do. Try to see what the marker does while driving and try to get the shift lines where the transmission feels smooth. Be careful while driving as you may get distracted and cause an accident.
