Well, the Moto-ST 800SS is finished, and the Sunoco spec fuel that
we'll be using this season has arrived. Out third rider also happens
to the be the service manager at my Harley dealer. We'll be meeting
with the bike's builder today and dynotuning the bike, trying to get
as close to the class maximum of 75hp without going over it, and also
trying to maximize our fuel economy.
Since our "B" bike dynoed at 70hp in dead stock form, we're a bit
worried that the "A" bike with the custom big-bore spaghetti exhaust
and open airbox will be over the 75hp limit right off the bat, and
we'll have to spend our efforts trying to dial it back.
Meanwhile, I've been working nights and weekends prepping the "B"
bike, since we'll be using it in the Team Hammer track day and the CCS
races prior to the Daytona Moto-ST race. We're still waiting for its
exhaust to be fabricated (in California!) and be shipped, which is
making me pretty nervous, considering we now have only 3 and a half
weeks before we leave for Daytona Beach! Did I menetion that the "B"
bike's bodywork hasn't been painted yet, either? H'mmmmm. Maybe
I'd better stop typing and get to work! |

Do you think it is wise to use the Harley dyno? I mean, by the time
you get it detuned to read 75 hp you'll be down to 50 real hp  |

Daytona is comin' fast. Ain't it? 
This year is gonna be great...
http://www.richiemorrisracing.com/News.html
See, now I can cheer on Richie Morris racing in SST(since Bilansky is a
good friend of mine), James Gang in GST(that whole crew are friends of
mine), and Screaming Duc for ST!
How much ya wanna bet that the 1125R is gonna do EXTREMELY well in the
SST class? >> Stay informed about: Ducati on a Harley Dynomometer |

Our bike was purchased as a stolen/wreked/recovered/insurance salvage
write-off. No key, non-working gauges, etc. With a late model
Ducati, that means the ECU is also a write-off. Not a problem, our
sponsor (and bike builder) is a franchised Ducati dealer. He simply
swapped the stock ECU for a 1999 900SS ECU. The bike starts and idles
fine.
However, on Sunday, when we went to dynotune the bike, it soon became
apparent that there was some kind of basic incompatibility between the
2005 800SS fuel injection system and the 1999 900SS ECU. We could
get the mapping dialed in using a perfoemance 900SS map as the base,
everywhere except the critical 3500-5500 midrange, 3/4 to full
throttle. The bike just has a huge hole there.
So, back to the drawing board. Donnie is going to be talking to
Magneti Marelli reps to see if there's a known problem, or look into
replacing the ECU or the duel injectors, or both.
Good thing we got to the dyno almost a full month before leaving for
Daytona! >> Stay informed about: Ducati on a Harley Dynomometer |

Do they dyno all bikes after the race? And are there any allowances
for different dyno's giving different readings, or changes in altitude
sapping HP or anything like that? >> Stay informed about: Ducati on a Harley Dynomometer |

So....what happens when you dyno on your dyno for 74.5, and get
challenged, and when they use a dyno in Florida after the races their
dyno says it was actually 77.2? >> Stay informed about: Ducati on a Harley Dynomometer |

If that were to happen, we would be disqualified. Since they tell us
what brand of dyno they're going to use, what program they will be
using, and what the maximum allowable horsepower is, then it is up to
us to be under that maximum on their equipment. >> Stay informed about: Ducati on a Harley Dynomometer |

I'm pretty sure all dynos have a correction factor built
into the software for correction to standard air density.
You might not see it as the dyno operator has control
of it but it's probably there.
Last time I was intimately involved was FUSA a while
ago and the dyno they used then had correction for
standard air density.
Go fast. Take chances.
