Just installed the ECM for the stock airbox and muffler and came back from a test ride. As reported here, the bottom (right off idle) is GREATLY improved over stock. It's also nice to be able to WFO in third gear without feeling like you've suddenly dropped an anchor, too. However, UNLIKE what I've seen reported here, I really haven't noticed any difference in off-throttle engine braking compared to the original ECM. Not sure why that should be (I didn't specify anything when I ordered the unit, just that I was running the stock airbox and muffler). Only conclusion? Someone at Erik Buell Racing recognized my name from discussions on BadWeb and tailored it based on my preferences, OR the difference in engine braking between the Erik Buell Racing item and the stock item has been greatly exaggerated. In either event, I'm happy. I was afraid I'd have to send it back to get it reflashed but it's fine the way it is. Thanks, Erik and Erik Buell Racing... and a HAPPY BIRTHDAY to "Da Man!!" | ||

I just went back, tried barker's + ecm. funny thing is, I have big difference with engine brake... very big! ps: so big that I'm planning to switch back to stock! (Message edited by Tsnake on April 02, 2011) | ||

Then maybe my FIRST guess was correct. Anonymous? Are you watching?? | ||
| Tsnake |
lol, maybe just because its for stock muffler. | ||

Tsnake - I am running stock ecm and barkers just fine. | ||

Jamie, my understanding is that the stock exhaust tune uses many of the stock ecm features like engine braking, and it flashes COLD till 150°f instead of 32°f like the race tunes. I got mine before the stock muffler calibration was available. | ||

Danny- thx, I think I will switch back the stock ecm to see. today there was a lot of traffic, I did not notice any great changes/improvements except the engine brake(maybe it helps on track, but bothers me on road, I used to brake with engine) the noise is bothering me,too but I found the ebr ecm really lowerd the noise level at idle. didn't get a chance to meet a policeman. I'm a little upset, because when I got the recalibrated ecm and freed the throttle(in france), I really found it's a different bike, a great improvement(ofc...), and now with race ecm, non-stock exhaust, and a KN filter, I didn't find it great, even the throttle response seems to be slower.(I reseted the tps 3 times) I also got a lot of codes with the race ecm, is that normal? I experienced two times, like a stall issue(but engine still running, rpm suddenly down), when I was just about to accelerate @ 1st gear.

Tsnake - How many miles do you have on the race ecm and barker. I understand it takes a while for the ecm to learn the setup. | ||
| Tsnake |
Danny- I think it's the cause,too not many miles, so I ll ride and see if I dont switch to stock!( oh no, stock muffler re-installation!) | ||

I sent my E.B.R ecm in for a KEDA specific tune and in the mean while I went back to the stock ecm. Yeah, I can't wait to get my race ecm back! The bike just runs so much better with the E.B.R than it does with the stocker. I have the KEDA RT2, velocity stacks and K&N filter and my poor R is backfiring and hiccuping like crazy and the low rev jerking is a cruel reminder of why I first looked into the E.B.R ecm to begin with. The engine braking is diminished with the E.B.R ecm in comparison to the stock as well. I am eagerly waiting for my ecm to be returned.,..,.  | ||

Froggy: That makes sense. Just smooths out the fuel delivery to what it SHOULD have been before the EPA got their hands on it. I surprised myself on my test ride... had the bike leaned over and rolled on the throttle the way I usually do and broke the rear tire loose. With the stock ECM I didn't have quite that much "ooomph" at that low an rpm. It was kinda fun, actually! I now have an idea of what it feels like to "back it in." | ||
| Jaimec |
Yep... DEFINITELY loving the difference! | ||

I experienced two times, like a stall issue(but engine still running, rpm suddenly down), Mine does that every time I start it, i.e. the first time I go to pull away it will stall (no it's not the "assisted take off"). I get around it by "blipping" the throttle slightly just once then all is well in the world... I can live with that, it's a habit you'll develop.. | ||

I keep forgetting to mention this: When using the race ECM, there's some value to disconnecting the clutch switch leads, in particular if you like very little engine braking. The IAC will return to idle when the clutch level is pulled in. So, if you pull the leads, as you are down shifting into a corner, the engine RPMs will stay up as the clutch disengagements don't trigger the ECM to deactivate the IAC. I first noticed this when I converted my race bike to the race wiring harness (where there is no lead for the clutch). I've since pulled the lead on my stock bike, and noticed the IAC working much more as I'd desire it to (reducing engine braking) even as I'm down shifting and feathering out the clutch. If you don't like the little blip of gas you get when you start to release the clutch lever, pulling the clutch leads will fix this. Now, when in gear at all times, the motor will probably run at higher RPM, depending on your IAC programming. You will notice this because as you coast to a stop with the clutch pulled in, the RPMs will be higher than idle until you shift the bike into neutral, as which point normal idle RPMs will resume. There's no "cost" to trying this on your bike, since the clutch leads have a connector that's easy to remove and put back right under the MC for the clutch lever.

thx, jd, well explained. I got that again yesterday, then I noticed that could be a clutch problem. and now seems to be a good feature? not an issue anymore. btw, I just reinstalled the stock exhaust last night in open air, with a maglite! I felt and feel great!! houra! | ||

It's my understanding (although my memory isn't what it used to be) that if you take the OTS (off the shelf) 'stock parts' variety E B R unit, the engine braking remains very OEM like. I noticed a slight difference OEM to E B R in terms of engine braking, but very slight. I'm pleased about that since I like engine braking ... Personal preference. The E B R box is easily the best $250 that I've spent on a motorcycle! Mike (Message edited by milleniumx1 on April 04, 2011) | ||

is there a cost to sending an ECM back to have a different flash put on it? I am trying to figure out what exhaust I want but I would like to get the ECM especially if I can send it back to get it flashed to whichever exhaust i decide on. | ||

Scottorious: http://www.EBRacing.com/shop/page10.html Other ECM customer support policies: If you modify your bike during the first year of ownership with components for which we have a pre-programmed flash, we will re-flash your Erik Buell Racing pre-programmed race ECM to suit the modifications for $25 plus $10 shipping. I don't know if they are enforcing the year limit or not. | ||

wow, cool thats cheap. Although Barkers exhaust is in my cart as we speak at American Sport Bike so I think I will just go ahead and buy the barkers ECM. | ||

It's also nice to be able to WFO in third gear without feeling like you've suddenly dropped an anchor, too. What do you mean by this?} | ||
| Fresnobuell |
What do you mean by this? It's a reference to the 'noid, The first mod of every R or CR should be the removal of said 'noid. It's for noise emissions but easily removable as it's a safety hazard and general nuisance. (Message edited by fresnobuell on April 04, 2011) | ||

If I remove my noid this weekend and I already installed my race ECM will I still need the resistor plug? Thanx! | ||
| Fresnobuell |
I don't think you need the resistor with the race ECM....it's already disabled so no check engine lights with the race ECM either way. | ||
| Drhodes1970 |
Thanx! It's outta there Fresno. |
