ECM spy setup 2008 XBSS

[Junkyard_Buell]

Hello,

I am trying to purchase the ECM spy program for my 2008 XB12ss. Is there anything I need to complete prior to downloading the ECM program? The manual tells me to download Mono runtime, which I did and now it is saying download USB drivers. I have windows vista and the cable from ASB, but just wanted to know what I needed prior to purchasing the program from ECM.


Thanks for the help.

Welcome!

In most cases, Windows can detect and download the driver automatically. So if you have already attached the cable to your Vista system and it has successfully detected and assigned to it a COM port number, you are ready.

Thanks,

Just bought this thing last week and its giving me trouble. During de-acceleration the bike tends stumble and sometimes dies. It is a 2008 and I did a TPS reset 5 different times, and not much changed with the bike. Changed the plugs and noticed the old ones were fouled due to running rich. Possible O2 sensor is fouled as well, but want to locate the problem before changing O2 sensor.

How can you tell which program to purchase?
BUEOD DDFI-3, XB, 2008 and later
BUEWD DDFI-3, XB & 1125, 2008 and later
BUEYD DDFI-3, XB & 1125, 2008 and later
BUEZD DDFI-3, XB & 1125, 2008 and later

I have a 2008, but it is a Japanese Spec bike. Are the codes actually on the old ECU?

Any help would be appreciated.
Thanks.

Take a look at the Installation section of the ECMSpy User Guide. It has instructions on which database to purchase:

Tunerpro RT is another program that can help you diagnose issues. If you can record a datalog with either program, I'll take a look!

Hey Buddy,

Thanks for the information and I got everything hooked up and running, but the bike is not showing any faults. I don’t understand because the bike is running very badly and randomly shuts off while riding down the road.

Are there certain perimeters that I should specifically be looking for? Like the TPS setting? It was siting at 4.0.
I am trying to just see if all the sensors are working.

Its sipposed to be at 5.5

There can be many causes. TPS can be fine at idle but become intermittent during operation resulting in all kinds of badness.

Thanks,

I took the bike apart to change the exhaust gaskets and intake gaskets. Now I'm having header installation issues. It seems the stud is off by 1/4" from the flange hole.

I've never had this kind of problem but this buell has been littered with problems.

Almost to that point of just parting it out on eBay.

This is a picture I pulled right after the bike was running seconds after shutdown.

The O2 sensor was reading .49 then up to .75, and after which it would drop back down to .49.

THe problem with the bike is that when I approach a stop or get near idea setting the bike tends to stumble and sometimes dies. It runs really rich and will foul plugs in a couple of weeks. I thought it was an intake leak causing the offset mixture reading of the O2 sensor. It runs okay passed 3000k RPMs, but not so much during stop and go traffic. If you could please help me out?

A single screen shot just doesn't give a complete diagnostic picture in this case. 318 RPM?
You mentioned O2: The O2 sensor is inactive in this screenshot. Rear O2 is 0.1 - it should constantly cycle above/below 0.49V w/ the engine running, so without an actual datalog (or video, at least) showing the sensor activity, it is not helpful in having a confident diagnosis. Now if you can tell me that the rear O2 voltage never changes, even with the engine at 138 C, then that is a issue and could cause the problems you describe.

That the AFV = 100 is a further clue that the O2 activity needs to be examined. I need data! Otherwise, we will have to play 20 questions.
