This device is will work on all models if used with the Eurodyne flash Windows software (with a USB connection) as well. It replaces the old USB only Powertap device.

User adjustable launch control (2-step) and no lift shift features are now available to our customers for the 2.0T MQB engines.

At the moment, North American MK7 GTI, Golf R, Audi S3 and A3 2.0T engine box codes are supported.

The ecu must be licensed for use with Maestro in order to access these features. See the FAQ for details on this.

In order to use these features, you must first flash your ecu with one of the LC/NLS enabled “loader” files. These files are available in the bottom section of the file download window, in the “for Maestro users” section. Click “show loader files” to access them. Once you have flashed the loader file, you can access the various settings by downloading one of the LC/NLS Maestro base files and opening the file in the Maestro editor.

Launch RPM settings can be adjusted quickly using the accelerator and brake pedals, without the need for reflashing.

On vehicles equipped with a DSG transmission, the DSG launch limits will override the launch limits set in the ecu, so you need our stage 3 DSG software that removes the DSG launch control in order for the ECU based launch control to work correctly.

Here is an explanation of the features;

Launch control:

Operation

Launch control RPM is controlled via torque control, (as with DSG controlled), fuel cut, or spark cut, configured using launch_control_config setting in Maestro.

When using torque control, the stationary RPM limit is used to control launch RPM. This method will be smooth, just like stock, but will close the throttle.

When using fuel cut, the control will be rough, with the engine rev’s oscillating, but will keep the throttle fully open. Fuel cut is handled using the standard ECU strategy, the control just indicates to the fuel cut function that all cylinders need to be cut. Spark cut will cut spark but not injectors.

Activate on MT:

– ESP fully disabled

– Clutch depressed

– Parking brake is not engaged

Once the clutch pedal is released or vehicle speed is greater than the Max vehicle speed for launch control setting in Maestro,  launch RPM control will no longer be active.

Activate on DSG:

– ESP fully disabled

– Brake pedal depressed

– Selector lever in D/S/Tip

– Parking brake is not engaged

The conditions for launch on DSG apply, so car should be in sport and brake pedal sufficiently depressed, etc.

Once the brake is released or vehicle speed is greater than the Max vehicle speed for launch control setting in Maestro, launch RPM control will no longer be active.

Adjustment

Adjustment can be made with the accelerator pedal and brake pedal.

When using the pedals to adjust:

Activate on MT:

– Engine running

– Parking brake engaged

– Transmission in neutral

– Clutch pedal not depressed

Activate on DSG:

– Engine running

– Parking brake engaged

– Selector lever in P

Pedal adjustment operation:

– Use the accelerator pedal to rev to the desired RPM

– When desired RPM is reached, tap the brake

– The MIL will flash twice indicating that the adjustment has been stored

– Release the accelerator pedal

Make sure the stationary rev limit set high enough in Maestro to not limit RPM adjustment during pedal based adjustment.

NLS:

NLS will use fuel cut or spark cut depending on config in Maestro to control engine RPM during shifts. When activated the system will take the current engine RPM, subtract NLS RPM offset, and control to this RPM until deactivated.

Fuel cut is handled using the standard ECU strategy, the control just indicates to the fuel cut function that all cylinders need to be cut.

Activated on MT:

– Accelerator pedal is greater than Minimum accel pedal for NLS

– Vehicle speed is greater than Minimum vehicle speed for NLS

– Clutch depressed

Once the clutch is released, NLS control will stop.

If you have problems running any of the Eurodyne PC software with windows 8, here are 2 things you can check;

You will need to enable the .NET framework, as this is not enabled by default on all versions of windows 8 and 10.

http://msdn.microsoft.com/en-us/library/hh506443.aspx

Also, in some cases you may need to run the software in compatibility mode.

The compatibility mode that has worked for 100% of cases to date is “compatibility mode for windows XP service pack 3”

Right click on the program icon, and in the drop down menu that appears,  click on “properties”

Click on the compatibility tab, check the “Run this program in compatibility mode for:”  box, and select “windows XP service pack 3” from the drop down.

Finally, click “Apply” at the bottom right.

You can purchase credits through the Eurodyne flash program, under the “Credits” menu.

You can also purchase them directly from this link, (you will need to enter your cable number manually in this case);

(copy and paste into your browser)

https://www.eurodyne.ca/shop/audi/flash-credits/

In either case, make sure you click the “return to Eurodyne website” link after paying for the credits if your browser does not do it automatically.

You can get your cable number by clicking “get cable ID” under the flash cable menu in the Eurodyne flash software.

The cable must be plugged into the PC while doing this.

The 2-Step feature of Maestro is now available for the following engine codes/models:

• AWP-AWW (2001-2005 golf jetta 1.8T)
• AMB (2003-2005 Audi A4 1.8T)
• AWM(2001 Audi A4 1.8T)
• APB (2000 to 2005) 2.7T

Disclaimer – The 2-step launch control system should only be used with a complete understanding of how it functions and the potential hazards of use.

The 2-step launch control works by cutting ignition momentarily and allowing
the injectors to continue injecting fuel. The unburned fuel will ignite in the
manifold and exhaust system allowing the turbo to build pressure while the
vehicle is stationary. The extreme temperatures from this can overheat and
damage components of your exhaust system (turbo, catalytic converter etc…) if
used for too long. For this reason we recommend that the 2- Step only be used
in off-road vehicle applications.

Activating the 2 Step and no Lift Shift features requires that you first
activate this feature using Maestro 7 and the following procedure.

1. Plug in your Powertap interface and launch the Maestro 7 software
   program – update if you are instructed to do so
2. Using the file menu open your current tune file
3. Select the 2 step and no lift shift feature (towards the bottom
   of the menu choices) this will open a feature selection screen
4. Select 2 step and no lift active and save the file to a new name

Once 2 step has been set to active you must flash the new file to the car and then enter the desired operating parameters.

1. Open Eurodyne Flash client and select flash ECU and select the file saved in the operation above
2. Once the file has been successfully written to your ECU select the “Quicktune and other settings” option found in the “Other functions” drop down menu
3. Select the 2 step and switching option tab
4. Set the “Speed” option – this will establish the road speed in KPH for 2 step deactivation – a setting of 2 will cause the 2 step to be active below 2 KPH and limit RPM to the level set in the RPM limit box (see next step). A setting of 0 turns 2 step off
5. Set “RPM limit” this establishes is maximum engine speed with 2 step active (vehicle speed below threshold set above)
6. Enter desired “No lift shift” value (allows driver to upshift with the accelerator pedal fully depressed by deactivating the ignition circuit to limit RPM for the time delay entered in milliseconds – once time delay has expired normal engine operation will resume)
7. Select the write setting button to save the values you have entered

This is a summary of the Powertap air iOS app functions. We will follow up with a video showing the app in action.

–Flash ECU from server

This selction will get the ECU info from your vehicle, and then display a list of compatible stage files from our server on your phone. Click select file to flash your ecu with the selected file after chosing.

–Flash ECU from Powertap

This selection is for Maestro users who have stored different tuned files on their Powertap air. This allows you to switch between the files stored on your device quickly.

–Log data

This selection will open the datalogger section of the app. This view also gives you a nice display of default parameters like boost and RPM gauges, along with a scrollable table view of other parameters. You can use the defaults, or select them yourself by clicking the select variables button at the bottom.

If you toggle “log to file”, the app will log data to a .csv file. if you toggle the same switch again, the app will prompt you to send the datalog file by text message or e-mail.

–Adjustable settings

This will read the adjustable settings from your ecu if it has been flashed with a file that has adjustable settings enabled. Files with adjustable features will have the word “Adjustable” in the file name when you chose a file to flash from the server. Not all models support these features. Set the boost limit and octane setting to your chosen value, then click “Write settings” and the settings will be written to your ECU.
