I just installed a new Jardine slip-on on my 09cr, the sound is great, a little on the loud side. I rode the bike home from my shop and it turned on the check engine light on the first trip. The bike does seem to have a bit of a stumble right off idle to 3500 rpm. Any ideas guys, any input is appreciated. |

What code did it throw? It's probably an AFV one, it may be that it'll correct itself as it learns the new requirements for the pipe. What are your f/r/ AFV values? |

Well Jules, I'll be honest, I don't know what codes they are. I don't know how to check them or the AFV values. I am a auto tech and do understand modern auto diagnostics, but I have had this bike a short amount of time and have not had the time to learn anything about it's diagnostic mode. Any pointers? |

hold toggle and mode switches, then turn on the ignition. You can scroll through all the diagnostics. |

Thanks guys, is there a way to adjust the AFVs? |

Yes and no... There's no way to adjust them without some type of external tuning kit plugged into the ECM either to modify the existing fuel map (my prefered approach) or as a "piggy back" that stays connected permanently (something like a PC V) That kind goes back to what Easy was saying aboout it most likely needing more fuel, he's probably right (he often is LOL) but it's wothe (a)checking the values (in diagnostic mode and (b) riding the bike a bit to see it the values can adapt enough to get it back into a range it's more comfortable with. IF it is that, then a Erik Buell Racing Race ECM would also resolve the issue (and at $250 it's a bargain) but you'd need to make sure that it is a fuel/air issue to satisy yourself first.. |

Just get the Erik Buell Racing Race ECM for the Jardine, and the problem will be gone. Take advantage of the huge amount of time we spent mapping all the parameters of the ECM to work with that pipe for only $250! |

So if I were to get this ECM from Erik Buell Racing I need to tell them what year, model, kind of pipe and what kind of riding I am doing. Anything else they need so I don't waste their time with 10 different emails? |

I have an 09 CR stock pipe, open air box, Erik Buell Racing ECM pump gas dieseling version. Wasted emails is true. I wished/emailed for the stock, complete decelleration no dieseling setting on the Idle Air Control (IAC) the second I found out about it on this site. They had sent it already. The IAC is like having a fat idle jet on a carb. It keeps the fueling going even when the throttle is closed. This dieseling effect was by design and considered beneficial to keeping the rear from breaking traction with this bikes torque. I like dropped throttle oversteer and the Erik Buell Racing dieseling version doesn't give enough for me, I will likely be sending it in for a reflash and have it restored to the stock IAC setting. |

Well, I just got back from a very spirited ride this morn, as long as I had my revs up, the light never came on. As soon as I started my commute home at a steady cruise speed, the light popped. Looks like an Erik Buell Racing ecm for the Jardine is in order. Gonna start saving my pennies. |
