My tune ecu adventure

You ran the engine while downloading the tune?????????????????????
Errm....no, I ran it a few minutes observing the gauge readings, just to make sure the battery was topped off. Shut it down, and THEN loaded the tune.
 
I feel dumb now.... it never dawned on me to pull the headlight fuse. I hooked a battery charger up when i did mine
Nothing wrong with that it's the best failsafe you can have when doing a map change
 
The underside of the fuse box cover on my 2011R3T has a listing of what each numbered fuse is rated and used for...takes the guesswork out of identifying which is for what without digging out the manual.
 
Pulling the fuse on my 2010 roadster kills the entire dash as well as the headlight !
