The stock map can cause the bike to run a little hot at certain rpms and loads because of how it was programmed for emissions reasons. Where I live, in Texas, that was a concern because it's 40+C for 6 months and 35C for another 3 months. Almost December now and it's nearly 30C right now. So it isn't a waste of time to richen it up a bit where needed if you know what you are doing. Obviously a better exhaust, or at least a slip-on muffler, and a better intake will be more satisfying.
The race ECM map was created for the Pro-Thunder race series in the USA. The map was optimised for the full race exhuast, K&N filter and Screaming Eagle 536 cams. The race series was horsepower limited to 95 RWHP and this simple combination of parts achieved that goal.
The race ECM is exactly the same hardware as the stock ECM, the only difference being the map. So reprogramming is all that's needed. No need to source a "RACE ONLY" ECM, unless you just don't want to bother with downloading and installing a map. But you still need to reset your TPS.
Will upload the map if there is somewhere to upload it to? Think its called BUEKA210
