CONCLUSIONES Y POSIBLES LIMITACIONES

DISCLAIMER: It should be understood that ANY changes you make to your vehicle’s stock settings can harm your vehicle and ALL changes are made at your own risk. The instructions provided to you here should only be used as guidelines to tuning your vehicle.

It is also critical that all hardware and sensors are functioning at 100% before beginning to modify your car’s ECU. We recommend checking the function of O2 sensors, MAP and the Mass Air Flow Sensor (if equipped).

Step 1 – Reflash your ECU with the license file provided to you in the registration e-mail as described Here http://www.eurodyne.ca/forum/viewtopic.php?f=20&t=174%20 in the How-To section.

Note: Maestro can ONLY use .csv log files created using the High Speed Logger. ***If you have an AEB engine with an M3.8 ECU you will need to use the ‘Maestro Logging’ feature in measuring blocks to create usable log files.***

Step 2 – After downloading and installing all software and drivers ensure your Eurodyne cable is plugged into your computer. Maestro 7 will only open if you have your authentic and registered Eurodyne Powertap cable connected.

Step 3 – Open Maestro 7 and from the file menu load your base .tapp file. Be sure to choose the correct base file for your hardware configuration. Each base file should provide you with a reliable configuration from which you can begin your tuning. Save your .tapp file often under new file names to ensure you do not lose ground if you need to revert to earlier settings.

Step 4 – If you have changed your injectors since obtaining your base file, open the Injector Wizard from the ‘Fuelling’

menu on the left hand side of the screen to scale your injectors.

Injectors can also be scaled manually using the injector wizard by entering the stock vs. new fuel pressure and injector size in the appropriate fields, then clicking ‘Calculate’

Step 5 – Open your Fuelling and spark maps to ensure the axis and RPM range are within specifications for your vehicle.

Note: Map descriptions can be opened either by right clicking on the map or by using the map description button at the top of most map windows.

Step 6 – Support for MAF-less configurations is available for some engine codes. If this option is available for your application it will be found in the menu at the left hand side of the screen and you will need to decide whether you will use a Mass Air Flow (MAF) sensor or not.

Step 7 – If you have already created a log file it should be loaded now. Changes to individual maps can be made quickly and easily by using the map tracing and histogram functions of Maestro. ***The histogram will provide very accurate feedback on which specific cells need to be modified, by highlighting and displaying the differences in map values then applying them.***

If you have already tuned a specific range in the map you are editing, you may wish to clear cells from the histogram before applying all values. This can be done by clicking and dragging to highlight cells, then right clicking and selecting

‘Clear Selected Cells’.

Step 8 – Make any adjustments to LAMBDA target maps and adjust Rev limits to desired values.

Step 9 - Save any changes under a NEW file name and flash the new .tapp file to your ECU.

Note: If your car has an irregular idle, a Throttle Body Adaptation can be performed now as described here:

http://www.eurodyne.ca/forum/viewtopic.php?f=20&t=191 This should be done periodically but is not required every reflash.

Step 10 - Warm up your vehicle. To ensure you are obtaining the most accurate data it is extremely important your logging and tuning are performed while the vehicle is at operating temperature in closed loop.

Step 11 – Using the flash client, clear all fault codes. Most importantly this will zero your fuel trims and erase any adaptations that have been made by the ECU.

Step 12 – Create a new Log file as described here HERE http://www.eurodyne.ca/forum/viewtopic.php?f=20&t=188 in the How To section of the Forums.

NOTE: While creating log files, attempt to cover as many different load settings as possible. The more complete your log data is, the more complete and accurate your tune file will be.

Repeat steps 7-12 as many times as necessary.

Step 13 - Once you are satisfied with your initial tuning, timing and knock correction tables can be adjusted in small increments as necessary.

Step 14 – Finally, make any adjustments to Cold start and warm up maps.

Quick Tune

Re-Flashing the ECU can take 5 minutes or longer depending on your system. For quick changes, there are ECU settings that can be modified through Eurodyne flash directly.

In Eurodyne Flash, click on "Read Settings". The Quick Tune menu will appear. If the ECU has a Big Turbo binary, Switching Active will be checked off and the maps can be flipped between Low octane pump and High octane race gas.

Once you have made changes in Quick Tune, you will be prompted to enter license key. If you have already entered it, click Skip Key. You will be prompted to turn the ignition on. Turn the ignition on but do not start the car. Click the Ignition is On button, and Quick Tune will close automatically after updating the binary on the ECU.

Note: Modifying your settings incorrectly can damage your car. Changes are made at your own risk.
