I went to the dealer last Saturday to order a Race ECM since I had a 20% off accessories coupon. The parts guy said the computer said the part was pending obsolete but still available. Anyone of any changes coming or are they discontinuing the Race ECM? Maybe just a dumb computer. | ||

As far as I know, along with the "race kit" the race ecm has been discontinued back in May of 2006 IIRC. Your next choice is American Sport Bike and their offerings. Neil S. | ||

IIRC Pipes discontinued, ECMs available. It's still on buell.com. http://www.buell.com/en_us/gear/accessories/Produc t.asp?Menu_ID=2&ProductLineID=4&CategoryID=1&Produ ctID=2213 Looks like its still available. (Message edited by barker on February 22, 2008) | ||

MB: I wonder if they have applied that "race only" to needing a race license to purchase, like they are doing with the rest of the "race parts"??? That may be why Greg's parts guy could not order one. Being PC has finally caught up with H-D (must really chafe their chaps). Greg: Depending on what options you have installed the Race ECM may not be the best. I know that 20% discount is REAL tempting but, having the proper map (for your particular set up) in your ECM goes a LOOOOONG ways to goodness and big GRINS!. The Race ECM's map is designed for the full Race kit: Exhaust and filter. BTW, in the next few weeks I know where a like new complete race kit will be offered up for sale, if you are interested.

I was going to get a Drummer SS soon and then maybe map it with ECM spy | ||

BTW I already have a K&N and was planning on opening up the airbox a little. I wouldn't put the ECM in until the exhaust comes. It should be in today and I will go pick it up tomorrow. The fueling on the stock map doesn't seem perfect so I can live with it I think. | ||

Looks like American Sport Bike has them: http://www.americansportbike.com/shoponline/ccp0-prodshow/17015.html "and then maybe map it with ECM spy" no need for race ecm per se. just use ECMSPY to "flash" a stock ECM with race data. (Message edited by barker on February 22, 2008) | ||

Yeah - the only reason to get the Buell race ECM is that you are using intake and exhaust with similar flow characteristics to the Buell race intake and exhaust. If you have dyno access, ECMSpy is a good thing, if not, talk to Al and get his recommendations. He's done a TON of work on fuel injection. One thing however, DO NOT ditch your stock intake/exhaust/smog stuff. Someday in next couple years, many states are going to start testing. I've got my stock S3 stuff in boxes in storage still. | ||

Barker, Don't know how much you know about ECMSPY and flashing data, but you can only flash race data to a ecm with the same last five numbers. IE GB231. There is a guy on http://buelletinboard.com/forums/index.php who will program a ecm for a cost. He has done a lot of work on ECMSPY and is involved in the development of version 2. Check the links out there or give me a call. Chris Dorn in Ohio listed in RAN. | ||

YOU CANT JUST FLASH RACE DATA INTO THE STOCK ECM. YOU HAVE TO MOVE ITS READINGS TO THE STOCK ECM AS THE LAYOUT IS DIFFERENT BETWEEN THE TWO. ANY QUESTIONS JUST ASK I USE THREE DIFFERENT TUNING SYSTEMS DEPENDING ON WHAT IS NEEDED. XOPTI ECMS (Message edited by XOPTIMIZEDRSX on February 23, 2008) | ||

Race ECM and filter are still available to order. | ||
| Chrislightning |
I have a K&N air filter and a Jardine exhaust but no race ecm. What would be the difference? Seems to run fine to me, or am I in need of the Race ecm. | ||

YOU CANT JUST FLASH RACE DATA INTO THE STOCK ECM. YOU HAVE TO MOVE ITS READINGS TO THE STOCK ECM AS THE LAYOUT IS DIFFERENT BETWEEN THE TWO. and the race ecm is tuned for the race exhaust, with other exhaust it not the best option | ||

Running the Buell race ECM is better than running your stock ECM if you have pipes and a hi-flo filter on your bike. Your motorcycle runs lean (hot) from the factory. Now add a hi-flo filter and a hi-flo exhaust and you have just leaned it out (hotter) even more. You need to dump more fuel into the mix to richen it up. Keep running the bike lean (hot) and sooner or later BOOM! Bye bye motor! | ||

THE STOCK ECM AND RACE ECM HAS A CLOSED LOOP LEARN AREA IT FILTRERS ITS OWN FUEL RATIO TO KEEP THE BIKE AT STIOCH BE IT HAVE NO AIR FILTER AND STRAIGHT PIPE OR A FACTORY FILTER. I KNOW THE ECMS INSIDE AND OUT. I CAN DO ANYTHING TO IT I LIKE MAKING THE MOTOR RUN HOW I WANT. ASK TQ FREEK HE GOT HIS WHEELS BLOWN OFF FROM MY XB9 AND HE HAS THE D&D WITH A RACE ECM ON HIS XB12. ITS ALL IN THE TUNING. ALSO ASK TREADMARKS I TUNED HIS BIKE FOR HIM. HE WILL LET YOU KNOW.. PLUS BUELL MAKES THE BIKES RUN AT 14.7 ON CRUISE AREA AND THE ECM MOVES THE TARGET FUEL FROM THE MAP TO THE AFR TABLE TO KEEP IF FROM 14.7 TO 13.0 BUT THE ECM HAS FACTORY GOVERNMENT RULES THAT YOU HAVE TO TAKE OUT. ITS LIKE A RESTRICTOR PLATE IN IT. TO SUME IT UP ALL ECMS WILL LEARN THE APPLIED FUEL AFV WHICH MOVES A % OF FUEL FROM THE FUEL TABLE FROM 60% TO 150% OF THE NEEDED FUEL FROM THE O2 READINGS FROM A 38 TO 72 MPH IN 5TH AT 30% TPS APROX. SO THIS RULZ OUT YOU HAVE TO HAVE A RACE ECM. THE MAIN DIFFERENCES ARE VERY TINY IN DATA BUT THE DATA IS IN DIFFERENT EPROM LOCATIONS THATS THE WHOLE TRUTH. ANY QUESTIONS? XOPTI. | ||

Uh.............. OK!   | ||

To rely on the AFV to be your 'race ECM' engines would have to respond to changes the same way (percentage of fuel needed) throughout the rpm range for all throttle positions. But they don't. | ||

correct!!! the silly ecm tunes for a sector in the cruise area then applies that data to the whole map. which is not the best way to do things. but its what we are given. so i cang the area it happens in to a much smaller zone and then . i work the area to get a stable afv from 98 to 103. and from there i can apply the afr to the table and make the fuel ratio com in in the open loop side to target a new afr and not affect the afv ratio. which is locked at a fixed 150% to 60% stock but i lock mine to 98% and 150% so my afv can never go below 98%. which makes my wide open throttle afr stable at 13.2/ in all of my open loop throttle positions. and 13.5 all other open loop zones. as well as buell times the applied fuel data to count 3 seconds before it kickes in. again why i dont know. so move that to one second on wot and open loop accell. then move the revaccel to 3 revs of applied fuel for surge air charge gain. this is set to one rev on a stock ecm and race ecm. all this data can be moved but not in directlink or ecmspy. you either need a race tuner or a protuner i have. that is fed from ecmspy. a lot of my things is done in binary numbers to get the hex alpha numeric number the ecm reads. so a 1101100010 would = f3 on a flip (example only not correct ) these long binary numbers do many things in the ecm. xopti | ||

Well it came in last week and I picked it up on Saturday. I spoke with Kevin today and I should be on the list to get a Drummer SS. So I will see how it goes. I am sure it will be ok. | ||

The Buell guys aren't stupid, far from it. There are reasons beyond just EPA compliance why the ECM is the way it is. Changes like you've described probably work well for a rider that uses his bike at a constant altitude (i.e. a rider in florida or texas). But when you start making changes that will limit how far and when the AFV is learned, you will make the bike less suitable for use across all altitudes. The current way the ECM is set up demands that the entire cruise range is tuned to 14.7:1 to prevent AFV skewing issues. Tuning richer than 14.7:1 across the AFV learn domain might make for a bike that has a little more pep for a given throttle setting, and if you've kept it from skewing the AFV, the bike will be great at that density/altitude. But it might be less optimized for other density/altitudes as a result. At some point, you might as well just disable closed loop operation all together and mask the fault bit. Which is exactly what the Henry Duga Race ECM does. It's a great track ECM, but I wouldn't use it on the street unless I lived at fairly constant altitude. Al | ||

Listen to Xopti... he has helped us out quite a bit and our xb12 went from a 13 sec bike to a mid 11s bike with a small tweek our first time out on it... its real smooth and pulls really really hard now, still needs some more work but X really knows his programing... |
