Product FAQ

You MUST read and understand all the instructions for your model before proceeding.
If you do not understand one of the steps, e-mail and we will explain that step.
This FAQ entry will outline the process of licensing a new vehicle for use with the Maestro tuning suite. Maestro is a software package that allows end users or tuners to access and edit relevant maps and other settings in the ECU.
First you will need enough credits to perform the flash. VW and Audi vehicles require 8 credits for a Maestro license. A new Maestro cable will ship with the 8 required credits. If you already have Eurodyne software on your ecu, the Maestro license may require less credits depending on the model. You can check to see how many credits are required using the software. Once a vehicle is licensed, you will be able to flash it as often as required at no extra cost. You can purchase credits through the Eurodyne website, or through the flash program itself. You will need your cable number to purchase credits, and you will need to be connected to the internet. You can get your cable number using the Eurodyne flash software (it is an option under the flash cable menu) you need to have the cable plugged into the PC to get the cable number (it does not need to be plugged into the vehicle to get the cable number.)
******Procedure for 1999 – 2005 models******:
*******DO NOT FLASH YOUR ECU FROM THE SERVER, you must use the Maestro base files available in the Maestro editor only on these ecu’s ********
The first step on these models is to read your ecu and send us the read. This will ensure you use the correct base file for your ecu type, and validate the communications on the vehicle. To do this, click “Start here” the “Read my ecu”. Once the read completes, e-mail us the read file, it should save to the c:\Eurodyne folder on your PC. If you have trouble reading the ecu, try a lower communication speed, you can set this under the flash options and com speed menu. Wait to hear back from us after we verify the read.
Prepare the base file you plan to flash to the vehicle by opening the Maestro editor, then selecting and opening the base file you want to use under the file menu.
You will need to be connected to the internet to do this, as the base files are downloaded from the Eurodyne server.
Save this base file to your computer.
Next, open Eurodyne flash, and click on “start here” then “License new vehicle for use with Maestro.”
You will be asked to confirm you want to use the credits to license the new vehicle.
Click yes, then select the base file you saved earlier.
You may get a message asking if you want to bypass the immobilizer. This is for ME7 ecu’s only, and is only neccessary if you are using an ecu from another vehicle, and the immobiliser is active.
In any other case, click “no”
the flash should complete in less than 10 minutes, and the vehicle will be licensed from that point on, and can be flashed any number of times after this.
******Procedure for newer cars (2006 +)******:
Below is a general outline based on year model and ecu type. If you are not sure about something, do not “try” anything to see if it works, or experiment. This is a good way to end up with a non functional ecu. Contact and we will assist by e-mail.
On the newer cars we have changed our system for several reasons, and now the Eurodyne flash software is used to display and download Maestro base files.
The first step is to license your vehicle and VIN. Once you have done this, you will be able to flash the ecu as many times as neccessary with any of the available files. You will need an internet connection for this procedure. Connect the cable to the car and PC, and then click “Start here” and then “License new vehicle for use with Maestro.” The software will license your ecu and VIN for use with Maestro.
On cars with MED17 and Simos ecu’s, the next step is to “unlock” the ecu for port flashing with Maestro files. This is accomplished by loading Stage 1 or 2 software from the server. The software should prompt you to do this. If in doubt, contact and we will confirm.
After this, you can click “Check available Maestro files” to see which Maestro files are available for your particular vehicle. You can then download and save the file to you PC for editing and uploading to your ecu. To edit the file, download the Maestro editor software from the Eurodyne website and open the file you had saved earlier in the editor.
For users with MED17 or Simos ecu’s, if you ever flash your ecu back to stock, you will need to unlock the ecu by flashing the stage 1 or 2 file file from the server before loading a Maestro base file, or you will have a no-start condition.
** We are unable to provide remote tuning, tuning advice, or review datalogs. If you need help with this, you should contact a tuner or tuning shop and work with them.**
If you have trouble directly related to flashing, licensing or reading an ecu, contact and we will assist by e-mail.

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:


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 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 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.

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)

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.

Step 1.Plug in your Powertap interface and launch the Maestro 7 software
program – update if you are instructed to do so

Step 2.Using the file menu open your current tune file

Step 3.Select the 2 step and no lift shift feature (towards the bottom
of the menu choices) this will open a feature selection screen

Step 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.

Step 1.Open Eurodyne Flash client and select flash ECU and select the file saved in the operation above
Step 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
Step 3. Select the 2 step and switching option tab
Step 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
Step 5. Set “RPM limit” this establishes is maximum engine speed with 2 step active (vehicle speed below threshold set above)
Step 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)
Step 7. Slect the write seting button to save the values you have entered
