i have an 09 xb12r with ceramic headers, k&n filter, and a drummer exhaust. shot ebr an email, and they said it would be difficult to predict the performance.. so i'm guessing the ecm is set for drummer only and other parts stock. so my question is, will the ecm be within a usable range or would it be skewed to where i should just get the whole package and map myself? prefer plug and play. | ||
| Andymnelson |
that's what it's made for....only difference Is the ceramic coating, which I can't see affecting it THAT much... | ||
| Madmodder |
alright thanks. tried doing some research and didn't come up with anything and wanted to make sure the headers wouldn't affect it drastically. also, did anyone get the self programmable kit? how does the interface look ? | ||

Copied from the Erik Buell Racing website. This ECM also works with motorcycles that have both race exhaust systems and a free flowing air filter. | ||

Hey Mad, Much of the recent findings and conversations on this Erik Buell Racing Drummer-Tuned Race DDFI-3 ECM has been kept to private emails and phone conversations between Erik Buell Racing, myself, and others. I know the whole point of BadWeb is to share the latest and greatest on issues, but I’d rather post something helpful rather than bore people with the immediate up’s and down’s of this development. In my opinion, this ecm calibration was released a little prematurely but Erik Buell Racing’s trying the very best they can to make the Buell community happy with all 8 employees working major over-time. To catch you up to speed on the current situation for this ecm: - The majority of users have found it works very well with their bikes. Stumbling at low rpms are almost non-existent compared to the stock ecm, throttle response is much snappier, power delivery is very smooth and noticeably greater than stock, decel-popping is GONE, and the latest fan cycle keeps the riders more comfortable. For this reason, you and many others may want to consider buying it. If things don’t work out so well for you, you’ll be joining my group below - A smaller group of users (including myself) have found this calibration leans our bikes out severely. I found my AFV dropped to the 70-80 range, at this AFV the bike ran so lean that it hardly idled, it hesitated at mid-range, and it had a general lack of power. This is very unhealthy for the bikes so if it’s noticed, it’s best to swap it out for the stock ECM immediately. The reason for the leaning, as explained by Erik Buell Racing’s lead tech, is due to over-correction of the Decel Learning function. This function was disabled and our bikes will now complete AFR compensations by only using instantaneous feedback fuel in closed loop looking at the 02 sensor(s) only. I found this didn’t work so well for me while in the mountains at Deal’s Gap (Tail of the Dragon) last week, so I forced the AFV to 100 and locked it there for the remainder of the week. The bike ran VERY strong and only had idle issues when I climbed up to +/-1 mile elevation. Now that I’m back at sea-level in Maryland, I’ll put the AFV back to normal and give it a try and post results later. There’s a big chance that if you installed this ECM, you’d find only good results but if you want to play it really safe, hold off until the ECM is fine tuned and the performance it more “predictable.” - Kyle - Kyle | ||

Kyle- That's a helpful write-up. Thanks for that... | ||

@Terrys1980: right, i missed that completely when reading the part description.  and as for the headers, i just got a new email from ebr saying significantly varying lengths would affect it. | ||

Erik Buell Racing just emailed me the Drummer map last week. I uploaded it and as of now there is no issues. No decel pop and no dead spots. | ||

"" forced the AFV to 100 and locked it there for the remainder of the week."" Hey Krueger08xb12s, Exactly how did you lock the AFV at 100. Mine runs the best at 109 and I'd like to lock mine there if i can. Thanks . | ||
| Andymnelson |
Artic- did they email you a map for an E B R ECM, or for your stock ECM? | ||
| Krueger08xb12s |
@ johnboy I used ecmread to change the afv MINIMUM VALUE to 100 so it's not exactly locked, but its not going lean on me. You can also set it to 109 with ecmspy then disconnect the o2 sensor. This'll make your engine light trip but i'd say do that for a few weeks of various riding before you change the eeprom. If it runs goofy on you, pull the seat, connect the o2, and ride on letting your bike adjust your afv. 109 may work well for a while but if you travel or weather changes, you may run pretty rich. My 2 cents. (Message edited by krueger08xb12s on June 14, 2010) | ||
| Krueger08xb12s |
Your afv needs to be able to adjust. Mine was put to 100 as a temp measure only, I'm not settling with a $250 ecm that doesn't adjust to conditions. | ||

I currently have a drummer with a k&N on my 08 scg. Definitely noticed an improvement on the mid to high range rpms with an Erik Buell Racing ecm. Idles a little high during warm-up but then settles down to normal. I bought it before they had one specifically for drummer exhausts. Do you think it would be in my best interest to see if they will reprogram it for me? My only complaint is I still get quit a bit of decel popping. | ||
| Krueger08xb12s |
@kbad, The cal u have got rid of my popping, but came with other issues, so maybe u have a leak. Get the drummer cal from Erik Buell Racing and if u still have popping u may want to look at your bike's intake/exhaust system. The high cold idle's actually better for your bike but isn't a stock feature due to EPA reg's. | ||

I would love to know how to get a higher idle when cold. Mine currently idles a bit low when cold. Not much of a problem except when it's below about 50 degrees then it tends to die without a helping hand on the throttle for a few seconds. Anyone know how to do this? | ||
| Resinboy |
I second the question: since installing a custom exhaust last year, my cold idle is too low, and generally stalls once or twice during start up. | ||
| Krueger08xb12s |
I believe you could adjust the "idle maximum engine speed" under "constraints/scalars" in ecmread. Stock is at 1480rpm for ddfi3 and it could probably be brought up closet to 1900rpm. Toy at your own risk. | ||

Andymnelson They emailed me a map for my Erik Buell Racing ECM. | ||

I put the original Erik Buell Racing ecm in my 08 bike as well. My mods were drummer and k&n filter. I didn't care for how it ran, had a stumble in the mid range, and it had a lot of decel popping. so I emailed them, and sent it back. They installed the new drummer flash, and it made a huge difference. I have about 400 miles on it so far, and not only does it run better, its getting better gas mileage too. I was only getting 42mpg mixed city and highway before. This last tank, riding it pretty hard, I got 48mpg. | ||

Sifo and Resinboy....assuming you are referring to your 2006 models, cold idle speed isn't a variable we can tweak. DDFI2 bikes set the idle speed by adjusting the throttle position. You also have some adjustability with fueling and timing, but the main tuning knob is the throttle plate. No easy way to correct for cold starts with the exception of the cold start enrichment (i.e. choke). Unless the XB's DDFI3 is vastly different than the 1125's, a IAC valve is used to control idle speed on the 2008+ bikes. No dice for the rest of us 'old timers'. Despite adding extra parts to the bike, I'd like an IAC for tuning purposes. |
