Easy maybe you should type first and drink later. Just saying. I know you'd like to be considered the ultimate authority on the tuning of the 1125r, but it aint gonna happen...not when the guy that designed and built the bike is still in business. So chill, type, then take a drink. So whether you understand perfect hoe things work and even if you did did it really makes no difference, at least to me. |

Thanks for the compliment, i dont find people in THE world that stay 5 days à week from 09.00 till 17.00 with à Buell on à dyno, for whatever type of tuning, not even EB, hè hires people to do that, and they can not afgord to do that, what i want to say is we choose to do this because we like to do so
So whatever happends, show me the people who make more hours on à dyno with à Buell |

Easy has a good point. The product he is selling has no fear of the long arm of the law, the Environmental Protection Agency.
A rich low end with lots of advance will give all kinds of power and likely smog. Everybody knows this. The balance of mileage and drivability is what we all want. |

So what is stopping Erik Buell Racing from doing the same thing? |

"So what is stopping Erik Buell Racing from doing the same thing?"
Has not CARB sued some companies in 2008 to sell not street-legal equipment in California? So West Coast Chopper had to pay $ 5000 for each bike in the show room. And Dynojet received a "collected" bill of 1 Million for its business activities.
So I take it for sure that Erik Buell Racing acts pretty cautiously regarding emissions.
One thing regarding WB-probes in the stock headers: This location is the hottest position available at the engine. This cuts costs, because an unheated and cheap single-wire probe does the job.
But the stock probe is a narrow-band-type. Such a probe is also effected by the heat of the exhaust gases, but not so far as a wide band probe.
A WB-probe measures the residual oxygen within the exhaust gases not directly but via a second reference cell inside of the probe which is guided exactly at Lambda=1. To perform this job this reference cell is heated to 750° C and the current, to heat this probe, is used as reference. The measurement by a WB-probe is therefore the control of that heating process up to 750°C.
This working principle has a consequence: A WB-probe only allows precise measurements as long as the exhaust gas temperature is below 750°C.
This means, a WB probe needs essentially some distance to the exhaust port, to give the gases inside of the header tubing some chance to cool down sufficiently.
This instruction is explicitly remarked within the Bosch application guide for the LSU 4.xx probes.
A LSU Bosch probe 10 inches behind the exhaust port should run hotter, Therefore the chance for accurate lambda reading should be fairly limited, when the WB-robe is installed into the stock header. |

That very well may be, but aren't these ecm's "race use only"? |

If you sell race use only parts with the appropriate warnings, and someone installs them on a street bike and is caught using it on the street, the fault falls on the vehicle owner, not the person making/selling the race use only parts.
If you sell a street-legal vehicle with those parts installed, then the seller may run into issues. |

I've been emailing E B R regarding the targeted injectors on the 08's , they summed it up pretty well here :
E B R : "It wouldn’t have the adjusted injector timing and a few other bits that improved low speed drivability and emissions for ’09 and 2010 model year bikes."
I have the E B R pump gas ECM , K&N filter and my HPE exhaust , does the E B R ECM have the capability to get the benefits of the injectors on my early 08 R ?
Ken,
"The short answer is yes. As coincidence would have it, the calibrations were developed on an ’08 bike with targeted injectors installed."
"The difference is marginal though."
Also for the HPE guy's :
Ken,
"Thanks very much for the feedback.
I’ll see what we can do to purchase and HPE, and work over the calibration a bit." |

Many thanks for the clarification |

So Mountainstorm, are you going to get the injectors. Seems I have followed a lot of mods you have posted in the past. Also, since you and I are running a full fairing, have you noticed a raise in temp's with the full fairing? I have, since I took the fairing off for testing with something else and I didn't want to continually put it on only to remove it again, I noticed a lowering in temp's on my test rides. Seems the full fairing around town may trap heat more. |

I'm thinking about it. I've not run without fairings since the Winter so not sure. I plan to take the fairings off before I bring the bike in for the 12K service so I guess I'll have a chance to check it out. Marginal improvements for not so marginal money are less interesting than marginal improvements made for free  like the IAT relocate, airbox mod, etc. But I do have the itch to tinker.
I wonder what it would cost to get an engine built up to an 1190...hmmm. |
