A buddy of mine basically gave a me a 2006 busa 13k and hasn’t ran since 2013 due to his wife making him choose family or bike. He. He said I could take bike because he knew I would bring it back to life. The bike is weathered but still in decent condition. Being that I am a mechanic I got it running in about hr after redoing brakes, empty tank new fuel, blah blah....he has a power commander 3 usb... I tried looking it up and found some stuff but here is my problem I was getting f1 code and read in another forum remove tuner and f1 went away which it did. So I came home and plugged tuner back in holding clutch in, turning key, and holding the 3 buttons down...ok now the green light goes up and down and shuts off. Tried it again still holding buttons I immediately release and start pressing low to raise and it stays on for about 2 pushes then cuts off and it’s like that with all buttons. I unplugged and replugged also cleaned ground and still same thing. What can I do to get tuner to work. Thank you ahead for all the help
