    EBR Race ECM rough idle

    2009 XB12SCG with EBR Race ECM with Jardine Exhaust and K&N air filter

    when I initially start the bike it runs great. I start to run into problems when the bike is up to temperature and am I stopped at lights and bike starts to sputter and eventually stalls. If I keep the rpm above 1200 it will run a little better and bike runs fine at highway speeds.

    has anyone seen this issue or know what is going on?

    I should probably wait til morning and sobriety to reply, but those are the classic symptoms of an intake leak. May not be your problem, but thats an easy one to check.

    Seals fine cold, but expansion occurs on warmip and idle falters.

    Like the others said a couple of simple things to check, IAC sensor or Intake leak test are easy to do.

    The IAC Sensor was cleaned and I could not find an intake leak anywhere.

    I have posted a couple videos of what I am experiencing

    Have you put the stock ECM back in? Just to see if you still have the idle problem. Could be the Race ECM isn't programmed correctly for the Jardine?

    No should be fine. Might have a little deceleration popping out exhaust.

    I ran the bike with the stock ECM with no issues. there must be an issue with the EBR Race ECM. anybody have any advice what I should do next. can I even send the race ecm back, ? can I reprogram it myself?
