Hi,

I sent my stock muffler from my 2009 XB12XT to Keven Dumm (KDFabrications) and had him make a dummer out of it and it really sounds good. I also replaced the stock air filter with a K&N. My problem is that it stutters and coughs when you increase the throttle rapidly. Starting off in first gear you must rev the engine a couple of time to start off. When decelerating it backfires something awful. I was told the stock ECM would learn (close loop) and correct for the changes I had made. Well I just rode the bike for 2456 miles last week and it has learned nothing. Still has all the problems it had when I left. Before I left on my trip I ordered an EBR ECM and installed it today when I got home. There is no hesitation at all, no matter how quickly you roll the throttle on. No more backfiring and WOW the response of the throttle is great. My problem now is the bike idles at 1600 RPM, and we who have a Buell know that is a very rough RPM you don’t want to spend a lot of time in. I read on some engines you had to reset your TPS. Is this true of the XB12XT and if so, how do I accomplish this. While on my trip I rode the Dragon (Deals Gap) and the Ulysses was superb is the turn. Thanks for any help you can give.
 
turn ignition on then kill switch,turn throttle full open for 1 sec then full closed for 1 sec. perform this step 2 more times for a total of 3 open /closed cycles.turn key off then on and start bike. ride for 20 min between 3500 and 5000 rpms.
 
Pro tip:

After the 2ed key cycle when you are done, listen for the servo. You should be able to hear it open and close. That way you know if it has been done correctly.

Good luck! [up]
 
Do I turn the key off between each full open and close cycle, or only on the last sequence? I think it says key on, kill switch on, and then 3 cycles of full open and close fof one second duration at each, but just want to be sure. Thank you for the help.
 
Rainman64,

Correct.

Switch On, Key On, Twist 3 times (1sec hold), Key Off, Key On, Key Off, Key On, listen for servo.

:D
 
ive never had to cycle my key twice at the end.just key off then on then ride for new ecm.maybe my 09 is different than yours
 
Not sure. But the servo dosnt move untill that second key cycle.

Warning: Im not an expert. I can only speak for what works for me. [cool]
 
Crap I thought so.. sucks to be me..I have ecm spy, cable, maps and driver just cant get the damn thing to work on my laptop. So I was just going to buy one from EBR. That or find someone that I'll pay do remap it for me.
 
What was the turn around time with KD Fab? I called a few days ago, and they told me to send in the specifics in an email. Hadn't heard back yet, just wondered what his normal time frame was. I ordered in an EBR ignition, but haven't installed it yet.
 
Mine was about ten days, however it varies depending on how many he has to do when you send your's in. My bike sounds great and now with EBR ECM it runs great with no more stutters and coughs off idle, also no backfires during decels.
 
I got the following from the EBR tech to do after installing the ECM.

Two things need to be done after install of this race ECM to make sure everything works properly:

1) TPS re-set
Turn key on and make sure kill switch is on run.
Do not start bike.
Turn throttle to full open and hold about one second.
Release throttle completely so it snaps shut.
Repeat full throttle, hold and release two more times.
Turn key off for at least two seconds.
Then you can turn on and start.

2) IAC averaging re-set
Start bike and let it idle for ten minutes.
 
Got a call from KD Fab on Friday, and mine is on the way. I'll report in when I get it on.
 
All my stuff is in, and installed. Did the air filter, ECM and muffler all at once. Have to say I really like the set up.

The Drummer SS isn't loud at all, at least not compared to the Bassani Road Rage on my Electra Glide. Really sounds good, and drives well.

More later, after I have some miles to report.
 
can someone help me I live in albuquerque NM, and my buell is a pig i've downloaded the ecmspy but can't find the cable the harley shop around here is a joke they want 250 just plug it in and 140 an hour after that
 
@ Sprinklerdude

I would take the bike up to Santa Fe HD, they are a much better dealership for Buells than Thunderchicken.

if not I can hook you up with a buddy of mine who more than likely has the cable.
