hey, i'm wondering what would cause the ECU fuse to blow? i'm sure there are numerous things but what are the most common?

 

Probably messing aorund and caused a short to ground somewhere...if it blew out of the blue ( sorry couldn't resist ) I would say a wimpy fuse or something is about to go really wrong in the ecu

just my 2 cents...and it is very possible to have a bad fuse and everything else be ok....just work on a Ferrari sometime...you'll see what I mean.

Have you done any mods?

Ciao
