I load the AED tunes with the silver key. with the steeda tunes they told me I had to load it with the silver key. With the JLP tune I loaded it with the red key and both keys ran the JLP tune. I havent tried to run the red key with AED tune. I dont use it cause I dont need to and its one less thing to clear in the morning when I start the car cause it will still say trackey active no matter the tune that is loaded but it isnt actually running the trackey tune.racered302 said:Justin, when you use one of your tune's, does it act the same with both key's? In other words does the tune cascade to both ecm's? Have you tried uploading a tune with each key to see if it made a difference?
