AM i correct that i have read that with the race ecm that some of the bikes still run really lean even with the race ecm??? | ||

If you're asking whether it's correct that you have read it then the only person who can answer that is you.. There are lots of posts on that topic on here already, have a look through the search function and you'll find more info than you'd ever want.. | ||
| Jonesz0003 |
i dont use the search engine on this forum cause well it sucks, but i was wondering that if you did order it and it still ran lean, if you could dyno tune the $250 or would you have to get the $750 ecm, and i dont need a bunch of smart asses on this thread | ||
| Jules |
Oh well in that case I won't bother answering... | ||
| Froggy |
Whats wrong with the search that it sucks? It worked for me.  Anyway I found a handful of good results with lots of information. Being that I am not an expert with dyno's and FI systems, I will not comment, but all the answers are out there. (Message edited by froggy on February 17, 2010) | ||

Hey i will take the challenge,if u wanna' be able to adjust it,you need to spend MORE MONEY,yes the 750 is the one u want if u r gonna' mess with it ur self....  | ||

The answer to your question is that you may have read many things, the general accuracy/truth of which relating to the EBR Race ECM may be quite dubious. As stated elsewhere in this Buell forum, one whose search utility is exceedingly simplistic, EBR has sold over a hundred race ECMs. Reportedly, all but one have produced significant improvements to performance. That doesn't happen by making a leaner fuel mapping for an EPA compliant sport bike. | ||

thanks froggy i appreciate it | ||
| Jonesz0003 |
yea i my buddies CR is a night a day difference from stock to the race ecm, i was just wondering if you can dyno tune the race ecm if it did run alittle lean or if you had to use the EBR, thanks for the results and help everyone | ||

theres only two that I've seen that hit the dyno. BOTH WERE VERY LEAN.One had no baseline so you cant really dictate whether it made gains.Its the truth.I dont know how many were dynoed of those 100 .Power commander has got a grip on this whole tuning deal.Just wait for their devolopment to be done.It will be very soon from my source.And the numbers so far are extremely good. | ||
| Froggy |
If you have the $750 software+ECM package, you can tune the ECM on a dyno till the wheels fall off. You can still get the software for $500, you just need to send the ECM back to EBR so it can be unlocked.  | ||

The Power Commander does not have any way to alter the timing. It's an add on. And I betcha it can't come close to what a properly calibrated ECM can do. How could it? | ||

Blackflash's comment: "The exhaust is also matched for that rpm so is the tuning .Thats where it makes power.So when your riding at 4 k like you stated it feels flat.Thats why.Its made for those high rpms." Black, I will agree to disagree on that one. My own 1125R I just test ran yesterday did not exhibit that at all. As a matter of fact it pulled from 4000 rpm's on up better then it ever did. Yes better at upper end, almost frightening, but way better from lower also. I believe, even though is a "race ECM" the one I bought (slip-on, K&N, pump gas) is for street use and tuned for that. Maybe its somewhat my exhaust but better all over the rpm range on my particular bike. Another thing that I believe is no engine tuned for very high performance, as our 1125's are, especially with enormous intakes, will like and respond to jamming the throttle open at the lower rpm ranges and it will always show a lean spike when doing exactly that. I have seen many proper dyno operators, although mostly on TV tuning programs, and they always roll on the power slowly. Even the graphs will respond better and show it. Bob | ||

You don't even know if the timing is different with the race ecm. The timing and fuel maps for the xb race ecm weren't all that great in my opinion and I bet if i search, I could find some dyno graphs showing bikes running lean. | ||

Bob That's could be a very shrewd statement. I never knew the mechanically reason, but i feel exactly what you stated. Whacking the throttle open at low RPMs tends to hesitate. Feeding the throttle open smoothly will reap much better results from low RPMs. +1 Bob. | ||

moosestang the race ecm has different timing its been comfirmed.But its not worth much more in power than a stock ecu with fueling changes and stock ignition leads.The loose of driveability is huge with the race ecu open style exhaust.Its soft down low.Now im curious how the stock exhaust will work with the race ecu.That would be the happy medium over a free flowing style.It might not be so soft down low.Also since all these bikes are running leaner with open styles.Would it almost be perfect with a less flow exhaust "Stock" Anyone test it with the stock exhaust besides j4b if he did. | ||
| Moosestang |
J4b is the only one i've seen and I'm not willing to spend the $250 at this point when I could just pay $500 for a power commander + dyno tune. | ||
| Froggy |
I have read on here EBR has a tune in development for stock pipe bikes. It would be interesting to see how that one runs. | ||
| Blackflash |
That I agree on frank.I bet that tune will be the cats meow. | ||
| Bob_thompson |
"The loose of driveability is huge with the race ecu open style exhaust" Blackflash, I again politely disagree with that blanket statement as me and I believe many others would not agree with that. My bike and I think many others have experienced better drive ability throughout the whole rpm range. Would you clarify what you mean so I can better understand it. Thanks much, Bob | ||

I'm not buying that the timing does not make a difference just like I don't buy half the BS that Blackflash puts out here. Instead of SPECULATING buy an ECM and run tests and prove all of us wrong. I just put about 500 miles total on my Race ECM and the low end drivability is better than stock. And where is BlackFlash getting all these pontifications from about the ECM he doesn't even have one on his bike. He looked at a picture posted on the internet and now he's got the last word on how the EBR ECM performs. Ridiculous. I live and ride in the mountains. Between 1500 and 2500 elevation. I had to crawl along because the roads are still screwed up with salt and gravel so I was going up and down very twisty backroads at 3K to 5K in first and second and rarely third gear. I got a real feel for just how much better the EBR Race ECM dealt with that than the stock ECM. Unless you have first hand experience how can you post like you know something? That's just BSing. | ||

Gents, having ridden old bevel drive Ducatis with (for the eighties) massive 42mm Del Orto injection pump carbs and Suz GS750s with 26mm flatside smoothbore Mikunis you soon realise that engines with big throttle bodies/carbs are not designed for high throttle loading at low rpm, ride the bike the way it has been designed to be ridden and use the rev range. Its not a stomp puller like the 1200 Thunderstorm engine so dont expect the same torque characteristics | ||
| Jules |
On the other hand - if millions of dollars of investments and decades of development can't make a modern bike run better than a early eighties offering with carbs on then something is wrong... As it happens the 1125 does run a heck of a lot better than any of those antiques. From what I read the SOTP experience of the EBR ECM is pretty good | ||

Instead of SPECULATING buy an ECM and run tests and prove all of us wrong. Justa4banger did that and got bashed for not being happy about what he found with the ECM. | ||
| Mountainstorm |
No I think Justa4banger got slammed because he was pissed and posted that all EBR ECMs are garbage. Sweeping negative statements condemning an entire product line base on one instance could inflame some heated responses. (Message edited by Mountainstorm on February 19, 2010) | ||

i am gonna buy one..i have no interest in having extra HP..i'd prefer better driveability...so what if it makes a few less hp...I can't and wouldn't know the difference anyway unlike some of the people here *(the bike has WAY more hp than i will ever need anyway) |
