I want to get a fuel controller because I plan to to get an intake and an exhaust and would like the bike to not run sloppy or lean. I dont want to get a new ECU because the Rev limitations scare me a little bit with how they might effect the valves at high RPMs.. I looked at the EJK website and it does not include the 2019 grom in the list of bikes the tuner will work for.. does anyone know if it works for the 2019? i cant imagine it wouldnt because it does list the 2018 as a bike it will work with im not aware of any changes to the ECU or injectors between those years.
