My roommate has a 07 Repsol and today he was trying to install this new power commander he got. Now the problem is when ever he turns the key on this FI led gives one long and three short blinks. He is trying to see what he did wrong, going all over those manuals again but I thought may be someone here knows about it or experienced something like this before and could tell me what the problem is.

 

Usally the F1 is problems with injections(fuel problems)

 

Thanks Andres. He solved the problem. He told me that the problem was the cable order. After checking all the connections and making sure they are properly done, the problem was gone.
