reflash the ECM
Thanks for the responses. I was curious because my neighbor pulled the ECM from his Yamaha and sent it cross country to a shop in Georgia where he had it reflashed. I think it cost something like $200. He had to provide info about exhaust system (i.e stock or other), etc and it was customized to his equipment and riding. He said it immediately smoothed out his bike and enhanced its performance. He said one of the differences was that when he came off the throttle previously the injectors immediately cut off and stopped flow of gasoline. Now they modulate giving the bike better overall response in all gears. Apparently bikes are typically "de-tuned" a bit initially at the factory/dealer. Reflashing optimizes performances. My neighbor is a bit of a gear head so he knows of what he speaks. (He had his diesel truck ECM refreshed and stripped off the emissions equipment to improve performance and eliminate the DEF system). I was not sure if reflashing the ECM would have any benefit for the CTX.
My general philosophy is "if it ain't broke, don't fix it". I''l just leave it be unless someone can give a compelling reason to do otherwise.
