     Krueger08xb12s |
So I've searched but have had bad luck getting the newest on the status of the 08+ ECM software out there. I know ECMspy is gone, but what else is out there for me to view and adjust my AFR, timing, etc? My 08xb12S has a power loss between 4-4.5rpm that i'd like to throw a little extra fuel at. All help/suggestions are greatly appreciated | ||

You can't just throw more fuel at that area. If you're in closed loop the o2 reading dictates how much fuel is tossed at it. I just switched from an 04 to and 08 and am figuring out how to tune it by manual hex changes. I might be able to help you at some point. ECMspy will still pull the eeprom data off the ecm and write it back. Ecmspy just doesn't know how to intrepret that data. | ||

How does the dealership tune these up? I ordered a service manual this weekend, but have not received it as yet. Is there a procedure in the manual to check timing ect? | ||
| Krueger08xb12s |
how can i figure out how to read and change the 'hex data'? Any recommended posts or tutorials? Can i still get the ECMspy software? | ||

You can always go to a race track, take a race school, get a racing license and then have access to all of the Buell race parts including a fully tunable ecm and software. There is a website that claims to have a spreadsheet that you can buy that allows you to use ecm spy to tune an '08 and later bike but I haven't seen it to try it on the dyno. | ||

I have an 09 Lightning will my ECM compensate enough for an open airbox mod and Odie muffler? or will I need some sort or remap? | ||
| Murraebueller |
I doubt it- the factory has always said no to that question. To know for sure, find someone with a dyno and an O2 analyzer and do a few runs that include full throttle and a variety of cruising modes. Full throttle is good between 12.5 and 13:1. Cruising can get up to 14-14.5:1. Higher numbers mean you're leaner. The only thing I'm currently aware of that you can tune an '08 and later bike is the Buell race ECM/tuning kit that you need a race license to purchase. I've heard of a spreadsheet that can be used with ECM Spy but I haven't seen it or used it on the dyno. | ||

Roy, you will be fine. A lot of guys on here have '08+ bikes with those mods and no fueling changes and they run fine. My '08 has just an open airbox and it's been spinning like a top for over 11K and counting. A tune would be good for optimum performance but not necessary at all. | ||

If someone needs a Ecm DDFI-2 , I have one of my 07 XB9R to sell . This will work with ECM Spy . PM me . | ||

Im really interested in any ideas people haev for tuning the 08+ bikes. Got my 09 dyno'd the other day, 86hp with nothing but a drummer. Those numbers are to low for a 12 IMO. The A/F ratio was like a winding snake up and down, and all of it WAYYYYYYY lean. | ||
| Murraebueller |
That's my point- no matter how great you think (feel) the bike is running, the air fuel numbers don't lie. If you're running too lean, the motor is running at a higher average temperature than it needs to and may be shortening it's life. Not to mention that it will make more power if tuned properly. | ||

Dude, I already told ya. Take your bike to JT&S and have them dyno tune it. Not too far from you either - you can make a day trip out of it. Check out their website: www.jtsperformance.com | ||
| Murraebueller |
It looks like a great shop with lots of experience. I would call first and make sure they have the software that allows them to get access and manage the data in the '08 and later ECMs first. If they don't have it, all they can do is make test runs and won't be able to actually tune the bike. . I've ordered the spreadsheet and will tune an '08 on the dyno with it using ECM spy as soon as I have it in hand. I can let folks know how it turns out. | ||

I don't understand how a simple spread sheet can suddenly make ECMspy work. | ||
| Murraebueller |
From what I understand, it allows a tuner to put in values that ECM spy understands and can communicate to the ECM. Sort of like a translator. HD uses a spreadsheet for the new "auto tune" mode of their latest super tuner and as a mapping support for regular tuning. It definitely works. Can't tell you much more until I actually see it and try it. It could be BS for all I know, but there's nothing else out there other than the pro race system form the factory. | ||

Jraice - what types of AFRs where you seeing? 86 is not all that low. | ||
| Froggy |
ECMspy will "work" with or without the spreadsheets, but the sheets make it easier to use. | ||
| Jraice |
Turk... I might've misplaced the sheet... But the AFR line was like a slithering snake and was pretty high, I think in the 16-17 range. I always could tell it was a bit lean down low but the chart showed that it doesnt get much better even all the way to redline. | ||

I'm about 2 hours ride from JT&S and talked to them last week about this, I also have an '09 XB12. They are working on an '09 right now and told me to wait for the result. They also said that ECM is different than older model years, which is why they told me to give them sometime. | ||
| Jraice |
I came into a good chunk of change tonight... If JT and S has promising results with that 09 then I might need to plan a ride up to Sonoma! Ever since getting my bike dyno'd and seeing how terribly lean it is I have had visions of 2nd gear power wheelies  . | ||
| Krueger08xb12s |
Rice u must be REALLY lean, my 12 powers 2nd gears easy, 3rd gear too at the top of hills or if i really power it. Will it pull in 1st without cracking or powering? | ||
| Gunut75 |
So........I'm reading all of this, and I'm confused. Don't the newer ECMs learn by themselves, or will they just move the whole fuel map up or down, leaving some spots lean, some spots rich? | ||
| Jraice |
The ECM's will adjust slightly but not much. And 2nd gear I cant get it to power, cresting hills etc... of course it wheelies. In 1st about a quarter of the times I go WOT Ill get a little lift. If I wind it up to about 4,000rpm then let off and wack it on, even to only 3/4 throttle it'll lift easily. Below 3,000 and its almost dead at WOT though so I need to really wind it up in 1st. Its not terrible, it runs good and pulls hard, especially in the higher end, but I think it could run a lot better with a tune. | ||
| Krueger08xb12s |
Yeah maybe i should leave mine alone. I have great power all over with the exception of the small dip at 4k. If anyone has or has heard about tuning these new bikes, please share! Thanks | ||
| Jraice |
I'd still call mine "running great". I just feel (and the dyno confirms) it could be pulling harder and lower. I still think if you can afford it that you should check out getting your bike properly tuned. My dad added a pipe and an air cleaner to his 96" Harley motor. Said the difference wasnt even noticable. He then had it tuned (gained around 10-15 HP AND foot pounds torque all across the RPM band) by a well known shop for building high strung harley motors, and said it was a night and day difference. | ||

I can re-map 08-up XB. Also I did subdivide the fuel map too. it is really works!  | ||
| Jraice |
Heard from JTS... They've done a few 09's. Said its $300 for the dyno, $250 for the key and he recommends a K&N filter and breather reroute mod before the tune. | ||
| Krueger08xb12s |
tarshi, what are the two purple columns on the left? TPS? Why 2 columns then? | ||
| Avc8130 |
Tarshi, What tables are those? How did you get them? ac | ||
| Froggy |
Those are the TPS values in both percentage and hex. |
