After doing a search I still cannot tell. Each time I plug in to my 10' yz450f it will give me hours, temp, idle speed, etc but will not put new map information on my bike telling me I am not connected to the ECU. Is there a fix for this? Pretty expensive little gizmo to read the hours. I have put fresh batteries in the tuner. I have tried having the bike running then connecting, connecting and then starting the bike with no change in results.
