Modifications, we’ve had a few. Efforts to remedy the KTM’s abrupt off-idle throttle response amounted to a G2 throttle tamer and updated injection/timing maps courtesy of TuneECU software. I can’t say enough about the capabilities and flexibility of the TuneECU deal. It allows you to make an amazing number of alterations to the ECU’s programming. Act responsibly, though, because you can wreak real havoc with incautious tweaking. To be safe, I used several maps found on the TuneECU site (tuneecu.com) and made subtle modifications to them, rather than starting fresh or building on the stock map. I admit to getting most of the way to happiness with the KTM’s responses, bridging the gap with my own adaptation.
