I am pleased beyond words, not only with the excellent tune for my stock 2018 H2 SX SE but the fast turnaround meant that I’ve been enjoying my new H2 over the Memorial holidays. He only received the ecu on Thursday, and before noon Friday it was reinstalled on my bike. Denver is not close to Fort Myers! Thank you David!!!
A few words about the flash, getting the ecu out without removing the fairing was tight, but care and patience it did come out smoothly. Going back in was actually easier, still tight but straightforward.
The included instructions called for resetting the ecu by making (3) 10 second starts at idle. On the fourth restart, good to go. The instructions stated there could be a CEL code come on which would have to be reset, with instructions given, however this was not the case, no codes were thrown.
I was hoping not only for the power gains at stock, but driveability improvements. It was immediately apparent the idle was smoother, the burbling on decelerations was gone and the transitions from trailing to part throttle were silky smooth. It just feels happy about the changes, really should come from the factory this way. It’s super smooth in L (touring mode), still calm and composed in M, uncorked but still linear and controllable in F. It’s pavement ripping in any of the modes, all the way to the 13,000 rpm peak, just a jet that only fails to take flight but you’re really not even sure it won’t.
I had a good feeling about Dave, as a racer and tuner, he was making good judgments to balance performance, safety and reliability. Everything still integrates beautifully, KEBC, KTRC, KIBS, the quickshifter, the fan, perfect integration, and crazy speed and power everywhere.
This should be the first mod on any H2 SX. Well done Dave!
