Finally fitted the EBR ECM with my Torquehammer. Did a TPS reset and she started first time. Warmed her up and set off at a trickle through the little village I live in. It seemed amazingly smooth and controllable so I imagined all was going to be great! Opened the throttle a bit more and it almost died. I continued to try to accelerate but is was missing bucking and very unhappy. Stopped did a TPS reset again......but it was still unrideble above 30 mph (50kph). So I went home and re-fitted the Torquehammer matched ECM. Ah well......I tried. (Message edited by trafford on April 25, 2010) |

Did you DEFINATELY disconnect your sidestand switch under the front pulley cover? Sounds like the electronic shift sensor. You might also wanna disconnect the BAS just in case.. |

Just finished installing a mew stator, harness upgrade and the latest version of EBR’s Race ECM for street gas on my 09 1125r with a K & N and Jardine Carbon RT5 slip on. Haven’t put it on the dyno yet but so far, it's about perfect. The first one they sent was OK but compared to my stock ECM with a ProTune3 bumping up the mix to about the maximum in most modes, the dyno showed it down a bit (+-9%) on power and torque. I talked to Michael about what we were seeing and he sent me another one with the very latest tweaks specifically for sea level environments and the Jardine pipe. Haven’t put it on the dyno yet but it runs great. Idle just below 1500. Got all the torque back that I originally lost with the Jardine. And, it seems to have picked up at least a few extra ponies. I’ll take it out today and run it up a bit harder. Dyno next week. Michael with EBR was great helping me through this and answering some questions I had about the harness upgrade. Anyone want a 6 month old ProTune3? |

Dorian: Let us know how it runs with the sidestand switch disconnected and then maybe the BAS. I have found that the EBR pump gas ECM runs fine with the TH. Later Neil S. |

That bucking is not any flaw in the ECM. It's the shift cut out be triggered by either the side stand switch or the BAS. Disconnect them both and the bucking will stop. Trust me on this as I have first hand experience. I posted about this when I received my ECM but it's been archived (i.e. buried forever). |

Thanks for the input I will try it when I next get a chance to put it on again. EBR said it would be set up for European sidestand. He forgot to do it....... but I just thought it meant I would not have the switch working. I did not think this would cause other problems.When I mailed them about it Michael at EBR did not tell me I would have to do anything other than fit the ECM. Just to start off clean I cleared the error codes with ECMspy.but this was just to see if it was easy....it was. Thanks to Jules and Mountainstorm for your advice. I will post results when I get the chance to re-fit. |

My apologies to EBR.....I misunderstood the email from them. EBR did say unplug it for race days......I missed that he meant the Sidedstand connection... Now I get it!! Getting old and forgetful...... |

Fitted the ECM.......disconnected the sidestand switch........amazing!! The bike is great now smooth at low speeds......pulls like a train from anywhere and is quieter on idle plus it was running cooler too. So I have left it on. |

Glad your baby is running strong again. Boy isn't it amazing how all the negative EBR threads turn out to be big misunderstandings. EBR Rocks. |

Would like my engine braking back though!!.....hard to please bikers isn't it?? |

I wonder if EBR could change the engine braking. Isn't that the IAC steps? Having a slightly lower idle and the same engine braking would make me even happier with mine. |

It's a race ECM. Most racers, such as myself, want little to no engine braking. That's just my opinion. |

I understand that the racers want no engine braking but I would love to know how to change if I wanted to.........anyone know how?? I have ECMread and tunerpro so if anyone knows which settings to adjust please let me know. |

I would love to go into freewheel mode, it would make coasting on hills easier It should be adjustable in Tunerpro, I don't know what would need adjustment though. |

No engine braking please. Also the idle speed will help adjust engine braking. EBR has upped the idle RPM specifically to help lessen engine braking. I would assume if you lowered the idle RPM, you could increase engine braking as well. |

I have a lower Idle but the ECM is 'intelligent' and is maintaining revs on decel |

Ok, I don't get it and it's entirely off topic. How would lowering the idle have an effect on engine braking at say, 9000 rpm? Changing the IAC would have maybe a 1-2% impact on the throttle position when closed. The butterflies are spring loaded, so the engine will still manage to overcome that resistance to draw in some air and fuel. I don't see how it will do anything for engine braking. I could see altering the vaccum for the clutch to reduce or increase the amount/effect it has for engine braking, but not changing the idle. |

There is no link between the idle speed setting and the engine braking (as you quite rightly say) |

I have ECMread and tunerpro so if anyone knows which settings to adjust for putting decel back to std please let me know. |

Sorry, but you guys are wrong. But what do we know, we only won the AMA championship. I'd love to see those who say idle speed doesn't affect engine braking having that discussion with a Superbike rider. |

Anony -- that's what we're asking here. How does it work? Is there something that we can change via the ecm? I'm new to the whole EFI/electronic control thing, so I'm still learning. Not sure which anony this is, but I assume it's someone in the know for tuning. |

Anon; Please continue and shed some light on this subject. |

Pretty simple, more fuel and air for higher idle means greater combustion happening in engine and less pumping loss during intake strokes and thus less resistance to deceleration. It's no different than holding the throttle open a little instead of having it fully closed. (Message edited by blake on April 26, 2010) |

Leaning out the Gas return area will increase engine braking. |

Anonymous - Having recently fitted my EBR ecm and ridden for a couple of hundred miles I can honestly say that the mods to the IAC have yet again vastly increased the grin factor of the 1125 R - which was from ear to ear to start with. Under closed throttle it acts like an old two stroke now, which is what I grew up on in the late seventies - those who do not appreciate how much easier it is to transition to entry into corners with moderate trail braking and how much more stable the bike is now haven't obviously had the opportunity to blast around on old strokers - The IAC is just right now - have to use the brakes a little more but that's what they are there for.

Easyrider= This was my thought and I am looking at the Decel cell figures and comparing to the standard ECM. They are quite different on the Race ECM. I just need to figure out which other cells might also be involved before experimenting. The Idle speed is nothing to do with it. It was this way on Carbs........ but on modern injection systems with multi sensors and infinite controls, engine braking is not down to the butterflys but to fueling and airbypass vents (IAC = idle air control valve). In ECM Spy for example on an XB it is simple to cut fueling completely on decel. (Message edited by Trafford on April 27, 2010) (Message edited by Trafford on April 27, 2010) |
