The lack of engine braking with the E B R ECM is something I expected and really don’t like. I plan to send the ECM back when they get the Keda RT-3 specific tune complete but in the mean time I was thinking I could over ride the clutch micro switch so the system thought the clutch was in all the time. What other systems does the clutch engaged/disengaged control? donald |

It has some input on the gear indicator, when the clutch is pulled in the indicator will read -- until disengaged. |

Can the engine braking be programmed back in into the ECM? |

I like the Erik Buell Racing ECM engine breaking set up. Does any one else? |

> Can the engine braking be programmed back in into the ECM To some degree. Low idle and things like that will increase the engine braking. I'll offer a word of caution, though: excessive engine braking can really ruin your day since when you are braking into the corner and need the rear tire to stay in place the most the engine braking encourages it to step out. Erik Buell Racing configures their superbike ECMs with a minimum of engine braking and the bikes themselves with a slipper clutch and the absolutely softest springs deliberately to reduce the amount of engine braking. A stock 1125r really has quite a lot of the effect, and I'd certainly not want more. |

I am with Jdugger on this one. It is a bit awkward and first, but the lack of engine braking is fantastic once you get the hang of it. I have no problem bouncing between my bone stock R and Erik Buell Racing equipped CR. (Message edited by froggy on August 03, 2010) |

Agreed. I plan on doing the ECM upgrade this winter during the off season and have become very comfortable with the amount of engine breaking exists in the stock ECM. I too wouldn't want any more, but would like the option to at least have as much as before as I have heard the ECM takes away the engine breaking to some extent. However, I suppose this old dog could learn a new trick or two with out as much engine breaking programmed in. |

What the race ECM does really well is help the transition from off to cracked throttle and even through the roll on -- power delivery is smooth and predictable. |

In about two day I can get used to either. Someone mentioned kicking the rear wheel loose. When I am going for engine braking the bike is vertical, rpm's are hopefully well matched to the decel-torque necessary to make it turn in to the curve. The rest is throttle control, leaning, and maybe some braking. It sure is darn nice to get a little extra turn in by letting off the throttle a bit! |

I believe the race ECM can have the same amount of enginr braking as the stock unit if you request it. I just said "I don't care" when ordering mine and i actually like the lack of engine braking (now) but it did take a bit of getting used to. It's more to do with the ECM control of the idle control than a lower idle speed itself. |

After installing the race ECM yesterday and getting to ride about 25 miles with it, count me as one who likes the reduced engine braking. |

I didn't like the reduced engine braking at first, but now with a few thousand miles on the Race Ecm.. I like it! |

> Someone mentioned kicking the rear wheel loose. > When I am going for engine braking the bike is vertical And that's fine on the street. Unfortunately on the track, that will get you stuffed by the entire field of riders behind you, and that's why you see my preference for as little engine braking as possible. Fast track riding -- at least at my skill level (novice) -- requires me to be hard on the brakes quite deeply into the corner and as I'm adding lean angle. There's little and sometimes almost no weight on the rear tire, and I want it the least temperamental about finding traction as possible because I don't really know how to deal with the rear end being loose under the brakes like that. Lots of engine braking promotes that loss of control at the rear end in these extreme braking situations. It can be miserable when trying to manage a difficult off-camber corner entry at speed. The extra turn-in you get from engine braking is really just the weight transfer to the front wheel under "braking", and it's something you would be best to learn to do with the front brake -- proper trail braking -- instead of by dragging the rear tire through the entrance of the turn. By having the front loaded early on the brake, you have the option of reducing brake pressure and yet still leaving the bike in gear. We've all taken a corner "dead stick" and know it doesn't feel right -- so I don't like the idea of only having the clutch available to reduce front load if the front starts to push under braking. |

It sounds like one of the few who thinks that even the stock ECM has insufficient engine braking. My 1125 has noticeably less engine braking than any other bike I've ever ridden. It's not a huge deal--I can change my riding style to compensate--but I'd still like more engine braking. |

isn't that the point of the "slipper" clutch design? |

Jdugger - THX. I can see what you are saying for racing and 'getting stuffed' into the weeds no doubt. I just can't get used to the dieseling, there are times when I am braking and it seems like I am not slowing or turning in enough so I pull the clutch in and the brakes come back or the turn starts. That's the scary part for me. More RPM's? |

> isn't that the point of the "slipper" clutch design? Sort of. Even the super-smooth racing slipper clutches seem to me for more dramatic events than just ordinary engine braking. They help, yes, but it's also the fueling and off-throttle settings of the ECM that help contribute to the bike's rideability and rider preferences. The parts worth together as a system. |

I really liked the change to less engine braking with the race ECM. I have much better throttle and braking control. |

Jdugger - No, I almost never use the rear. |

is there a difference in the engine braking being removed on teh Erik Buell Racing ECM than going in and killing it on the stocker? i killed it on the stock one and didnt care for it as it would let the bike stall when approaching stops |

Boogiman1981, you adjusted something wrong then. No stalling issues with the Erik Buell Racing Race ECM. |

froggy that is entirely possible using ecm spy i selected fuel cutoff in decel and as far as i can tell there is no further adjustment as far as when that occurs. i was thinking it would be good to be able to adjust that rpm point say fuel cutoff in decel above 3k or something like that |

With my stock ECM, the engine braking was ferocious to the point of being a nuisance. The posted descriptions of the race ECM offering less engine breaking was one thing I was most looking forward to. The race ECM I was sent didn't provide even the slightest reduction in engine braking. I was very disappointed, but the positives outweighed that particular negative. Now, this thread comes along, and I am seeing all these posts about their engine braking being reduced so much, that it's too much. Makes me wonder if there is something wrong with the race ECM I have....? I sure wish I had the problem of too little engine braking! |

Attweco - did you specify that you wanted lower engine braking when you ordered? It's an on/off function that may be "off" on your particular unit. just out of interest what's your idle revs? |

Now that my post has been turned into a pro or con engine brake thread, does anyone have any valid input to my question "What other systems does the clutch engaged/disengaged control?" thanks donald |

Clutch engaged off you go, clutch disengaged no go go... yes no one has answered your ? Donald ,seems everyone went off into their own tangent & forgot what you were asking mate.. |

Could that be when you let out the clutch the rpms come up like the stock ECM? |
