My bike actually seems to be running worse, it seems to alternate between running real smooth and making decent power(not often, maybe 20% of the time) to running noticeably rougher and being down on power. Even when it's running at it's best, it still seems noticeably less powerful than pre-3rd flash. This has become real obvious to me over the past couple of days. At this point, the bike has to go in the shop for the dipstick/ sidestand recall anyways, so I think it's parked until then, and hopefully they find the problem. | ||

xb9, 4012 miles at first dyno run, 7133 at the second. The first dyno run was with the first reflash (second map). Jack | ||

bump... | ||
| Jmr1283 |
it does hurt alittle bit to get off the dyno with 118hp. I should know! lol sucks | ||
| Slypiranna |
????  waddaya mean?  | ||
| Easyrider |
My first dyno had 122 HP ?. So it's not that bad to start with (-; | ||
| Hogs |
So... Easyrider what is yours NoW with the exhaust stock ecm with the lastest flash done both HP and Torque, Also any more sound clips YeT???? Damn I wish them 88 /90 kits for the Xb 1200 would WORK 115-120 and 100 pounds of torque should EASY meet them 1125 results with a few other mods to go with them Kits... Its really Strange that these kits for the Xb`s have NoT taken off I mean 115 RWHP and the Torque wd. be MORE trhan the 1125 what Gives....3 or more years NoW and No one has them down YeT???

Hogs, I'm pretty sure both Zippers and NRHS have the 88 and 90 inch conversion kits for the XBs...What do you mean nobody has them down yet? Are there issues with them? | ||
| Easyrider |
hogs, see the graph:  blue graph is 09 flash, green one is stock ECM. Exhaust is still waiting for materials to come for welding can be done, when the first one is ready I pick up the bike and make some sound clips. | ||
| Rfischer |
"stock ECM" '08 Stock street or Race ECM with base map? | ||
| Easyrider |
rfischer, 08 stock NO flash street ECM. | ||
| Spectrum |
Has any one got a dyno chart on a stock 09 yet? | ||
| Mustangturbo |
So have we come to the conclusion that the reflash of our 08' bikes has actually reduced power? I hope not! | ||
| Thurstonbuell |
I believe it did , the seat of my pant's dyno is all I have to confirm this tho . (with 2nd reflash) I saw in Cycle World the 09 GSXR has three ECM mapping modes , MODE A: normal ,MODE B: smooth low to mid rpm or MODE C:smooth across the whole rev range , proving how difficult this mapping issue is to get all aspec's accomplished using one map , and keeping it within tree hugger regulations .

Here we go again. BMC should step up and a) PROVE that we are wrong about the reduced power after the last flash b) fix it with yet another reflash Loss of power was the ONLY thing I was concerned about regarding the last flash. I posted the question various times before actually taking the bike in. This is very disturbing. | ||

I'm really not worried about a 6-10 HP loss off of the top end. The bike runs better and has better drivability. The third reflash is a welcome improvement in my book. I really do not use that end of the RPM range with my riding. The bottom line is whether it's 118 or 126 rwhp, the bike still has more power than I'll ever need/use on the street. That being said, I can see how advanced riders and regular track/racers would be upset. I would however like to see what a stock 09 looks like. If it's still in the 125-130 RWHP range then I'd like to see another 08 reflash or 09 injector/map upgrade option. | ||
| Fresnobuell |
Why do we have to settle for losing HP in exchange for better drivability? Buell stated that the top end would not be affected. I bought a bike that advertised a certain amount of power. Why should I have to settle for less? Some 2009 bikes should be hitting the dyno, so time will tell...and hopefully soon. | ||

Xb9 has an 09 1125R and he dyno'd at Western Reserve last month...looked great! I cannot recall the actual peak number...as I never judge by just that...but it was up there! Now, where is he at? He can fill you all in. I'm loaded for another dyno round! This is better than, well, you know!  ...and can't wait to test Easyrider's stuff too!

I hope to give you all access to my made fuel map on the dyno and hear what you all think about the drivability.. hope to have some time soon to finish it. I think it's a combination of both worlds, good drivability and HP and torque on top end. | ||
| Chevycummins |
Easyrider, all I can say is your a great guy, going above and beyond anyone's expectations in Buell performance! Thanks again! | ||
| Jpfive |
Fresno, I am waiting for the '09 dyno runs also. First complete tests should be hitting the mags next month. If the runs look good, then I figure I need to fix something on my bike - or another flash needs to be coming. Jack | ||

i love those scoops on ur air box. Mind fillin us in. | ||

You know when Ford came out with the first 320Hp Cobra in 1999 with the new body style and the IRS rearend, some of the new owners took their cars to the drag strip and found out that the car wasn't really making 320Hp and that infact it was much less. Ford immediately fixed the problem and was careful to never let it happen again. I love my Buell, but I bought it for what it claimed to be,if it can't live up to it then I don't want it! I didn't pay 12,000 for broken promises. I was afraid there would be some power loss. This is absolutely dishonest!! I will get the dealer to buy it back before I accept something less than what I paid for. | ||

'09 1125R, WRHD Dyno, 660 miles, Box stock, 5th gear it was 128.85 HP, 72.60 Ft/ lbs.Torque That's about where it should be with 146 at the crank,figuring the power train losses and a really fresh motor. seemed like an accurate dyno. It's still tight. I can tell it's a runner. AFV's are both at 110.5 The torque is a line not a curve. Looks like a high power diesel with revs. Same with the A/F ratio, a line about 14.0, no bumps, nice and linear. Except it showed 14.5 - 15.0 at the low end. Looks like an excellent tune for a stocker. They could not get the sniffer into the muffler very far, so he said it could be off some. Now we also did a short A/F dyno log on a steady state cruise about 4K, it was reading between 15.0 and 16.0. F'ing emission standards. My thought on that: Who needs closed loop if you have good maps  I've got my own ideas on why some of the '08s with miles on them are showing low numbers. Leak down tests may tell the tale. Extreme heat and lean running is not good on an engine. Just my opinion, not fact. (Message edited by xb9 on December 04, 2008) | ||

Easyrider, you have mail, and thank you! | ||
| Mustangturbo |
Were you ever able to run this against the numbers put up by a bike with the last tune? I would like to see the numbers compared. | ||
| Xb9 |
I'd like to see a fresh '08 on the dyno with the current calibration, one that wasn't run with the two earlier cals. I'd bet a beer it would put up the same numbers as my '09. | ||

Ok, I just apparently fixed atleast one problem. I was thinking I might have some sort of spark problem, so I pulled the aircleaner, and took a good look at the coil plug-ins. It seems the front one wasn't seated all the way onto the coil and locked. I had to pull the lower snorkel too, and take a real good look at the front connection. It wasn't locking, I had to make a shim out of rolled duck tape and jam it under the catch, so the tab would hold the connector locked. This has probably been an issue for a while, as the bike is running much smoother and better now. I think my previously mentioned bad gas was an intermittent poor coil connection. It still might be a wee bit down on power to the previous flash, but it's running the best it has since the reflash. And to get back on track, I can hardly wait to see the finished exhaust.

ANother question, is it possible to remap for improved power, and yet still keep the o2 sensor feedback open for the economy and emmissions purposes? This is probably my main question about the ecm spy and the tuning software aids that are out now. I really would be interested in it, especially as I am starting to get real interested in the idea of a new exhaust. | ||
| Xbswede |
Yes you can remap for increased power and still maintain the O2 sensor. You just have to stay out of closed loop region so you don't mess with the ecm pre configured AFR. I commute on my bike so this what I am doing now. |
