Put a D&D on my 12r, well due to some miscommunication with the dealer, I won't have a race ecm or filter for another couple of days...the bike seems to run fine, start and idle OK, so the ? is what do the ecm effect? The timing? fuel curve? the bike seems a little down on power compared to stock, will the ecm restore some lost punch? I'm probably going to "swiss cheese" the air box also...BTW ear plugs are the order of the day with this pipe! Thanks | ||

good luck with that ...I am running the D&D, filter and stock ecm could not get the race ecm to work on mine.. (Message edited by spyder12s on August 07, 2004) | ||

Spyder12s , Can`t you take your ecm back and say theres something wrong with it,?? I`m running one never had a plm. with it at all works great..with all your same gear plus the snokle removed..?? Just wonder could yours be screwed up?? | ||
| Black9 |
Well, I swissed the air box very similar to Timbo,and I can't believe the difference! I can crack the throttle in first, the wheel comes up and pulls!!! all with stock ecm/filter...way better than stock..gotta say the drilled box plain works.. | ||
| Spyder12s |
we tried and tried with no luck think we even tried 3 different ones..and replaced everything with no luck | ||

Call D&D and ask them if you need the Race ECM. I seem to recall when I bought my D&D hearing/reading(can't remember where) that it wasnt designed with the race ecm in mind. Now, I rode it for 5k+ miles with the race ecm and had 0 problems. I did have an XB9 though, not a 12. With the stock ECM thinking it has to control the valve in the pipe, Im curious how it acts though | ||

Well let me ask this question. Will drilling the air box on a 12r do anything for the bike? Tatsu | ||
| R1DynaSquid |
No. | ||
| Odie |
Why? | ||
| Black9 |
Trust me, just as in the "9' it works...any time you can get an engine more air, it's good. People should'nt be so quick to assume that what works good/ bad on the "9" will be the same on the "12" Different stroke, header size, displacement, etc.. means pipe mods,timing changes, will show different results, but more air to any engine is GOOD. | ||
| M1combat |
It works Dyna... At least on my butt dyno it does  . | ||
| Opto |
At any given rpm the 12 motor would be "trying" to pump 20% more air than a 9 motor, so I would think that the benefits would be greater for the 12, but mechanical things don't always follow very simple logic. | ||
| Odie |
Nor do women...... I drilled my box saturday night and have yet to ride it (12S). Riding to work this morning and will see if it feels different.It sounds louder that's for sure. | ||
| Trenchtractor |
Spidey, Had the same problem as you (and Opto). My 12 just will not work with the race ECM. End of story. It's not the ECM, cos we tried more than one, and my "faulty" ECM worked fine in another 12. As for the drilled out air box, it works. You get heaps more up top and better throttle response... Now the bike WANTS to rev. Sorry Dyna, it's the truth, besides you've gone over to the (japanese) dark side now... :-) | ||
| Spyder12s |
thank you trench , was waiting for you to back me on this one... | ||
| Elkman |
I've seen other posts about swiss cheezeing the airbox. Is there a right or wrong way to do it? Instructions? | ||
| Darthane |
You may wish to avoid drilling on the reinforcement grid (the raised lines on the underside of the box), and I believe Trench thinks one should stay away from the riight rear area due to heat, but other than that, have at it. People have used 3/8" to 3/4" or justt cuut huge portions of the box away, all with the same results. | ||

You guys are gettin to me . I am seriously wanting more ... Power, response.. Noise!... I just don't have the nads to start hackin away.... so let me get this straight. just drill a few 3/8 holes in the airbox cover. preferably left front, and do or do not remove the snorkel? | ||
| Hogs |
Deerhunter17, check out the other thread== Jens and alex | ||
| Odie |
Deer, I used primarily 3/4 inch holes and smaller ones where the 3/4 inch ones wouldn't fit. | ||
| Opto |
...and my "faulty" ECM worked fine in another 12. You never told me that Trench, did it work fine in another bike for more than a few weeks? Point is, is the race ecm or the bike with it's combination of sensors at fault, this is the BIG question. If the answer gets down to something really simple (which it will) like the ecm will not accept certain variations in tolerance of say a tps sensor or combination of sensors (anyone replaced a tps to get the bad ecm going? - I don't think anyone has) then I am going to fridjenstunkkin shidztnitz.} | ||
| Spyder12s |
Opto we did replace the tps and just about all sensors ..and two or three ecm with no luck.. | ||

Just keep the bad press about the XB12 race ECM going, I still haven't gotten my XB12R to run properly with the race ECM. It's a $200 paper weight and I can't wait to give it back to Erik at the next event. I love everything else about the bike, but that frickin' ECM really burns me up. Mike L. | ||

Also posted in the "PING" thread... My bike had ALL the ECM related sensors changed and neccissary recalibration done as required (several times). Whats more, all those sensors had to be borrowed from a NEW 12 that was in the shop as the parts were not available. MY SENSORS WERE ALL TRIED IN THE OTHER 12 AND WORKED FINE!! Point is, nothing (including 18 HOURS OF SHOP TIME, retarding the timing and replacing ALL THE SENSORS) could fix the following problems on my bike with the RACE ECM: 1. Pinging. So bad the BUELL TECHNICIAN started to call it "ping on demand". 2. Surge when cruising. 3. Failure for the bike to settle to idle in a timely fashion. I'll say it again 18 hours, of shop time, with a Buell technician, all new sensors, new ecm, all of my parts were also tried in another bike. Once again, some 12's just aren't compatable with the race ECM, either that, or the 12's that are working with the race ECM will start to have the same problems when they get some miles up. I got the stock ECM and it's great. Actually runs a bit rich up top, bet you guys won't believe that, either. But then what would I know, I've spent 4 months trying to fix this problem. Answer from the factory was stick it back to stock and leave it that way. Seriously, that's what they said. I think I'll be buying the Binelli 1150 naked next time. I'll shut up, I feel much better now. Signed, Frustrated at the lack of Buell Corporate's tech support. | ||

I took my bike to the dealer last week to have a TPS reset. He hooked it up and did his thing, came back out and said "This is the best running buell ive ever had in here" Apparently there SUPPOSED to run rough at low rpm,and SUPPOSED to occasionally backfire/hiccup thru the airbox???? aw •••• never mind this is a 12 thread ive read it alot on here that the race ecm simply donsnt work on some 12s (Message edited by stonecoldbuellin on August 11, 2004) | ||

Ok, since my 12r runs great w/ stock ecm, filter, drilled airbox, and D&D ,should I even install race ecm, or save the $$$$, i'll still use the K&N, but I haven't received the ecm yet...don't really want to throw $$$ away, on something that "might" work, and if it does, no better than what I got now. | ||
| Hogs |
Black9, I`m told with that configeration that your bike wd. run LEAN , I`m not sure if thats true or not just what I have been told by the buell tech. here, But not sure if he knows or not?????Whats everybody else think on that?? | ||
| Glitch |
Whats everybody else think on that?? Lean, I think. | ||
| Hogs |
btw, I just installed my D&D in the past week or so, and I did call D&D for some tech. questions during install and he did tell me that he recomened the "RACE" ecm for what thats worth, never got the doods name should have... | ||
| Opto |
Black9, my 12 with K&N, Drummer and stock ecm does not run lean. AFV 100%. Most 12 race ecm's work well, that's why the few of us with the ones that don't work are so peeved! (plus we spent wasted hours taking the bike in, picking it up, wondering what's going on, frustration, wasted time effort and money). The K&N makes noticeably more power and is worth the money. I don't know if the race ecm makes any more power or not, that could only be decided on a dyno, since I haven't heard of anyone with a 12 with a working race ecm ever putting the stock one back on to compare them, nor have I heard anyone say their bike (XB12) runs better with the race ecm. It's a lot of money that maybe could be spent better on something else. |
