So, got on dyno and pulled back to back EBR ECM vs Stock ECM. Jardine exhaust, stock filter, etc... This is the STOCK ECM... 125HP and substantially RICHER than the EBR!!  Here is the EBR ECM, 124 HP and LEAN...  | ||

Any ECM learning time between runs? | ||

Any ECM learning time between runs? I was about to ask the same. I'm guessing nope. | ||
| Froggy |
Hard to figure out what is going on in those pictures, but I don't see anything lean. | ||

Greg - Can you scan the entire graph, then shrink it a bit so we can see the entire plot? | ||
| Stirz007 |
I plan to run my bone stock baseline dyno this weekend, then mount up EBR exhaust and ECU afterward, so I am interest to see your overall baseline run. How much learning time on the new ECU before it becomes smart? I am concerned that too much time between baseline and EBR run will change run conditions too much to get meaningful comparison results - any thoughts? | ||

Gregt, with all due respect but far too many questions here to answer yet and have a credible result for one session on a dyno. I see you are brand new to BadWeb with just 14 posts so what is your reason for posting something the could be construed as being highly negative for EBR products? Are you satisfied with how your bike is running? Why did you buy a Buell 1125? Lets have some more "reliable" information so we can make a reasonable conclusion to what is going on here. Looking forward to further posts and more info. Thanks much, Bob | ||

The data points aren't even on the same scale. One has the target a/f at 13.4 and the other is at 13 but both are showing relatively the same numbers and they track pretty much the same for variations up and down and both ran 14:1 or lower, which isn't really super lean. It's definitly tough to tell what's going on there without seeing what the scales are, what rpm/speed it ran at, what gear was it in, etc. Do you have the run files from the dyno, or just the printouts? The ecm's need time to learn and adjust, I found that out myself when I tested my original exhaust. Ride it for at least a week with the EBR ecm in it, put 250+ miles on it. Force it to learn, ie; ride in 3rd or 4th gear at 45 mph for several miles, flat road if possible. You'll usually know when it changes some, I could actually feel the difference in power output when it happened. | ||

I agree with Dean. You need to make the thing learn your bike and environment. | ||
| Xoptimizedrsx |
yep with out a learn in the environment you wasted your time. did the dyno operator have the dyno set as progressive weighted to the bikes co factors or was it just free spinning? If the load was not set correctly on the dyno to the bikes natural resistance that's another strike against the run file. If you can get the actual run file to post many of us will look at it and analyze non bias with the factors given. (no learn and no correction factors for the bikes weight and wind resistance.) Overall Its a run file that will tell me nothing really accurate.(IMO) mike | ||

Gregt, What you can do is disconnect the 02 sensors, then you see the real data that is used to set the individual cells. And then Run the Bike again. In the same way. You will have a good compare how the ECM are programmed and for what purpose.. | ||
| Stirz007 |
I realize this is probably covered under another post, but it wasn't immediately obvious to me, so pardon the question: What information should I give to the dyno tech? Namely, what air resistance factor and other 'input' data needs to be provided to get the right set up for my baseline run? Thanks | ||

What information should I give to the dyno tech? Desired hp and your bank account number. | ||

Stupid question but does the ECM have to re-learn if power is cut (ie battery removed from the bike?) | ||
| Dirty_john |
suppose it does but cutting power to my standard ECM didn't reset the AFV as I hoped it would recently | ||
| Fresnobuell |
Question revolves around my track bike with the race ECM. I would like to disconnect the battery between track days, but not at the expense of the ECM having to learn each time out. | ||
| Dirty_john |
Can't help you with that I'm afraid, but there are other posts on the forum that suggest that the ECM relearns after each TPS reset as well. | ||
| Fresnobuell |
Eh, I can keep the battery connected and just put the tender on it the night before the track day. No biggie i guess. I would like to know for curiousity sake. | ||
| Dirty_john |
just leave the battery connected and hook the tender up, this is what I have done for years, with one tender for every bike. |
