One thing that you'll want to check is the battery on the bike. If you can, leave it on the battery tender while you're doing the work with the ECM. I unplug the headlight fuse while I do this, in order to make sure there is as small a load on the battery as possible.

I'm sorry to hear you are having such a tough time with this.

Yea it's unreal,I have a toggle for headlight off,have trickle charger on battery all the time,but do take it off for the procedure.Next time it will stay on and I'm trying to find a laptop with a serial.
Sert engineers,when they were kids must have been pranksters who hid behind a tree to watch after they glued a keyhole up in a car door.

Glad to hear. Sounds like a PITA. Glad you got it worked out. I'll tell you honestly, I downloaded my latest map to my bike today, and was holding my breath until it was done.
