Sent my ECU off last Monday to Shoodaben Engineering to get it reflashed. Got it back on Saturday, very good turn around! Took the bike for a nice 96 mile ride this morning to check it out. First, the throttle response is so much better. No jerky starts from a stop, and letting off the throttle at speed is much more gradual. No sudden fuel cut. The low rpm response is much better as well, I found myself not having to down shift nearly as much at low speed as the rpms dropped. These were the biggest obvious changes I noted and to me it makes the bike much more fun to ride and safer to boot. There are other changes made that were not as obvious but these alone made it worth the reflash. Highly recommend it.
