Over the summer I purchased a low mileage 2004 S4R will a full Arrow exhaust. The previous owner claimed it had and ECU to match the exhaust but wasn't really able to give me the specifics. He said at the time he bought the bike from the dealer, they told him the arrow setup was the only one with an ECU. Can anyone tell me how to identifiy the ECU I have? Not exactly sure where to look.
I also have my suspision that the dealer meant that the arrow was the only one that didn't require and ECU.
Oh, it also has a stock airbox and cleaner, so any thought on that would be cool.
Thanks!
