How to update firmware and load a base tune

IF YOUR ECU IS NEW FROM US, IT HAS FIRMWARE AND TUNE PRE LOADED!

Step 1. Download the newest version of SpeedyLoader, the Speeduino firmware and base tune program.
Step 2. Use SpeedyLoader to update to the firmware of your choice.
Step 3. Click “Get Base Tune”, this will save a copy of the base tune you select to your “Downloads” folder.
Note 1: It’s important that your base tune that you select matches the firmware signature that comes on it. Loading mystery tunes into mystery firmware will create interesting results.
Note 2: It’s extremely important that you select a base tune that has the correct Board Type that you purchased. If you load a tune with the incorrect board type, it can cause catastrophic damage to your car or ECU.
