I think I answered my own question an hour ago, but I'm posting this in case someone else is confused.
My Programmer is just over a year old. The instructions it came with say that when starting the bike, the LED's will scroll across for a few seconds and then go flashing or solid green. A YouTube video I saw confirms this, but mine doesn't do that. It just comes on with a slow flashing green LED at the #1 position.
Also, the manual says that if no button is pressed within 5 seconds, it reverts to normal. Mine reverts in about 2 seconds. Also, my "yellow" LED isn't really yellow, it's more of a green and red combination.
At first I though I had a bad unit, but looking online, I found a PDF of the manual. It's been revised. The part about the scrolling LEDs has been removed, though it still says normal reversion is 5 seconds. Until you get the hang of it, 2 seconds isn't much time and can be very frustrating.
Anyone else's unit behaves like this?
