There's no a/f data in those files, it's pegged at max lean as if the probe wasn't stuck in the pipe. |

LOL...that's because the probe WASN'T stuck in the pipe. Chalk that one up to me actually listening to the damned tech again, figuring that he knew more about what he was doing than me.
Blake, I'd love to think that the first two runs are the more accurate ones, but the second set (runs 003-005) are more in line with what the majority of other 'bolt and Lightning owners are reporting, which is why I'm more inclined to believe them. I don't recall anyone except me reporting HP numbers in the low eighties with only a race kit installed. But ultimately I don't really care, either, so it's a moot point. If I'd wanted huge HP numbers I'd have bought a damned GSXR. That being said, I am seriously considering getting the Force system this winter...should make the bike that much more fun, and then Mary Jane won't have a snowball's chance in Hell of keeping up with me.

I'd like to know how a dyno can be tuned. I'd not be surprised at a race kitted bike making 82 rwhp. I'd be very surprised to see a race kitted bike making only 75 rwhp. Stock XB9's make 75 rwhp. If you paid money for those dyno runs, you really should get clarification on what the tech meant about the first two runs not being valid due to an "improperly tuned dyno."
Sounds like complete BS to me. Was the tech just attempting to explain the drop in power in subsequent runs after you asked him about it?
He didn't know enough to put the probe into the tailpipe?!!! You gotta be kidding me.
You know I'm very skeptical, but based upon what I'm hearing, your dyno results are very suspect. See if you can get clarification on the "improperly tuned dyno" question. If you don't get an answer, you might ask for another set of runs, this time with the A/F probe in the tail pipe.

It's my understanding that before they came out with the Dynoware EX hardware with the weather station, there was correction factor calibration procedure the operator had to go through, to measure atmospheric conditions and then input them into the software. I've never done it so I don't know much about it, although I've seen it done. This would only apply to model 150's and older that have not been updated to the Dynoware EX hardware. Perhaps that's what he's referring to. |

The correction factors for his runs 002 and 003 are all within one percent of each other. |

No, Blake, he knew where to insert the probe (feel free to interject lewd comments here), but he didn't think that he could get it far enough in (see above parentheses) to get an accurate reading. As I said, my mistake was in thinking that he'd know more about it than me. Maybe he was right, maybe he was wrong. Aaron would be the person to answer that.
As to the whole accuracy of the dyno thing, I'd love to think that my bike's making nearly 85RWHP, and when people ask, I'll continue to tell them that his best run was 82.7HP & 66.2FT/LBS - a totally true statement even if the readings were bad. 
Curse my frazzled thought processes - this is the last damned time I'm editing this post!
I will take the bike somewhere else one of these days so that I have another dyno run to compare it to.

Fellas:
I did some puttering today in the dyno room , this is that S1 "track use only".
Here's what is done to it :
It's still a 1200
Forged Wiseco Thunderstorm pistons
Screamin eagle .536" cams
Crane adjustable pushrods
Jim's roller rockers
Zippers windage tray
1998 oil pump
2002 Crankshaft
Ported heads / milled
Buell Pro series race exhaust
Mikuni HSR 42 ( I don't like em but I'll make an exception in this case )
Forcewinder air cleaner
There's still more there , the needle is not correct for this application but it's all I had ( man they are fun to change !!!)
I won't at this time post the air fuel / graph , the reason ?? , many who show them here use " multiple graphing for this feature , I don't feel that this is an objective way to view or interpret an air / fuel graph , it should be displayed alone. When shown as a muliple graph at the bottom of the page it sure looks sweet , nice and flat , when the same data is viewed alone it looks far different and can then be dissected and be dealt with as needed. Later I'll bring home some floppy's with the entire Buell file to update my at home version of winpep , then I can show some examples of what I just typed. |

That looks great! I think "flat" on the A/F curve is relative. I look at the actual numbers. It would be nice if Winpep would allow a third full sized scale on the y-axis. |

Perhaps I should rephrase thae statement I made , ........
When viewing the air / fuel graph as a stand alone , the data is more easily read as it is an enlargement , the actual numbers being shown in greater detail than can be shown on a multiple graph. What I have observed is mulitgraphs do often look more impressive , until changed into air / fuel only , then can be picked apart , the flaws easy to see. |

Our dyno was a 150 before it was a 200 , before it became a 250 , and yes we had to manualy enter the atmospheric conditions when it was pre dynoware EX , pain in the ass ? , you bet !! If the conditions were not checked and entered every couple of pulls , the result was varied and inaccurate. |

Fellas:
As promised , here's more on what I stated above , please ignore the quality , these are scanned prints I brought home. I tried to use a floppy to transfer some files to my at home version of winpep and failed miserably ( I'm such a doofus with computers ). Also , when I am successful at moving files on floppies the results are often lower numbers due to the drum mass number being different on my at home version , the one at work has a higher drum mass ( eddy curent brake version ).
This pull is a multigraph showing horsepower , air / fuel ratio and RPM , the air / fuel graph looks cool , the horsepower is lame.
Here's the air / fuel only , it sucks !!
Later on that day after building a new map things seemed a little better , sorry I forgot to print the air / fuel graph , it was improved but not yet perfect.
About a month later after some "tweaking" and more work on the map the HP / TQ graph looked like this ...................................
This was over a year ago , more to follow ( while I have the scanner fired up ) |

One year later ..................................
After some more "tweaking" and work on mapping , the HP is up ( there's more in there ) and again looking at this mulit graph veiw of the air fuel ratio , everything seems to be quite happy.
Here's that air / fuel ratio graph as a stand alone , much easier to see the actual numbers.
The initial lean spike is from whacking the throttle open and is not a sign of a lean condition , the rest of the graph is only slightly on the lean side and is flat , this is the beauty of a power commander , the ability to adjust fuel at a variety of throttle positions / RPM 's.
Here's the HP / TQ .............................
Oh , don't ask me any specific information about this particular motorcycle , I can't tell you ( maybe this winter ) , This is all I can say , it has two wheels , a relatively small four cylinder engine , is naturally asperated and not very expensive to build once you figure out how it's done. |

Let me say hi to everyone here and give a big thanks to all the great info this board has to offer
my friend picked up his 2003 XB9S saturday installed the racekit about 1 hour after he picked it up today just after turning 500 miles we had it at the dealer to be dynoed
list of mods
snorkel removed, VS trimed, Race kit.
***She turned 81.6 HP SAE***
The local dyno is pretty dead on
my fully done up R1 has put down 148.4
One XB layed down 74.4
one with a race ecm and race muffler layed down 75.6
One XB with a race muffler K&N and 1050 kit layed down 82.6
One fully modded hayabusa 164.4
(Only listed other bikes to show the dyno is not askew)
Anyways we are very happy with the numbers and how the bike runs we will soon be finishing up the airbox removing the top and making a lid for the filter also to come soon will be a nillan force Exhaust. we will keep you posted
Also as soon as I get this graph scaned I will post it up
Thanks alot Jeff(gone looking for a scanner) |

That would be a 1250 kit, not 1049 |

Great job! Does this mean you're gonna start selling 1250 kits? We'll make you a helluva deal  |

Can't Wes go back and squeeze that last 0.2ft/lb out of it  |
Pammy

Wes probably would, but we don't let him in the dyno room very often. He has more important work to do. |

Help!! I'm not real happy with this curve. I knew I would likely have a mid dip but is this magnitude typical for an otherwise stock 99 S3 with Race ECM and K&N with gutted airbox?

What've you got for an exhaust system?
Looks like it's got a bad reversion going on there.
Did you take an a/f plot? Betcha it goes fat through there. |
Blake
| | Posted on Wednesday, July 30, 2003 - 02:00 am: |

No A/F info? Looks more like a stock S3 than a race kit S3. A free flowing muffler would probably help a bunch. The race kit totally inverts the torque dip; turns it into a hump. The difference it makes in the bike is huge, 20% more power in the mid range. |

Hey Blake,
Are you giving away a free t-shirt or something for the first XB12 dyno chart?

'99 M2 Cyclone (sold)
'04 XB12R Firebolt (coming soon!)
'94 Turbo Miata |

You bet. I still owe Hoser one for the first XB9R dyno. |

Aaron,
It's the stock exhaust. No A/F, free dyno time at the dealership open house.
Blake,
Only the ECM and K&N are changed. So this is typical for the stock exhaust?
I have a race header in the shed but no can to go with it. Sounds like its time. Is the D&D for race header discontinued?
Thanks all |
