I've read that if the RB's map is adjusted too low in the RPM range it triggers a engine light. This came from Yaman at RB. I'd run this by him for a correction.I’ve got a 2017 1200S with an SC Project Carbon Oval. I had a Rapid Bike Evo put on and that’s been a complete cluster. The RB does cause the bike to run better (pulls stronger). However, I’ve been getting a check engine light since the install. Very frustrating and not remedied as of yet. The SC Project exhaust is a home-run, though.
