Yea its very different seeing an engine on a test stand at 7700 rpm vs riding in a car.
Its funny seeing customers faceswhen they see thier engine running on the dyno for the first time. Some look horrified and nervous.
I dont think I can change the poll?
Lost power? Gee whats up with that? was it a dj250 with a gas analyzer?

quote:My limited experience with dyno tuning and PC3Rs has been the one time I watched a friend dyno his gsxr1000. He changed his ignition and fuel settings via a laptop that was plugged into the PC3R. The only other connection between the bike and the dyno was the connection to read the rpm. My question is
Are you actually hooking the PC3R to the dyno's computer and making changes to the PC3R's settings with the dyno's computer
Since most computers (cept laptops) come with two serial ports, the same computer talks to both the dyno and the Power Commander.
quote:or are you making changes with an external computer that has the PC3R software on it and doing multiple pulls on the dyno to see what the results are and making adjustments to improve the results??
That's the primary method used until the advent of Tuning Link. Tuning Link eliminates a pull for each cell on the map, instead adjusting all the cells for the entire rpm range a bike will reach at a given throttle position in the accelleration mode. In the steady state mode, it adjusts for each cell at a given rpm, for each throttle position. So the questions I ask the customer are:
(1) What rpm do you cruise at? (steady state)
(2) What is your priority, mileage, or performance?
That way I establish some base A/F ratios to work with, and know what range to work on for steady state tuning.
quote: That's how the guys I watched were doing it, i.e. make run, modify settings, make a run compare to previous runs, make adjustments. Incidentally, there was nothing measuring the composition of the exhaust.
I'd say that they weren't really doing it correctly then, kinda flying blind without realtime A/F ratio measurement.
quote:I think I've seen what looks like a gas analyzer hanging from the pipes in some of the photos. How important is that measurement in tuning the bike for peak performance??
Very! You *have* to know what the A/F ratio is to effectively tune the bike!
quote:Also my friend with the 00 12R has a PC3R and an Akaprovic pipe but he is using DynoJet map for the Akaprovic. He has not made any other adjustments to the map and seems to be happy with it.

Thanks SWFT.... Appreciate the detailed information. There's lots to learn about the latest technology out there and you're a great help. I assume you're a certified tech and dyno operator, is there a listing of others across the country or someone in the midwest you can recommend?? I'm in OH and the shop in my area (S&K Racing) has a dyno but not the full capabilities to tune on them. Thanks again for the info, wish I was out west because I'd definately would provide you with some business!!
Thanks for the photo Dave, that helps too!! Incidentally some of us Daytonians (we're in Dayton OH) are planning to hang out at Bike Week 7-10 Mar, love to hook up with you.

BMW - Yep, went to the school last year, and operate a DJ250 with all the goodies. And that mobile setup looks sweet!

BMW - There were quite a few 12's that were here last year and a lot of us got together at a breakfast compliments of Doug Meyer and Rob Muzzy. http://communities.msn.com/2001DaytonaBikeWeek/muzzybreakfastdelanddrags.msnw I'm hoping the turnout will be as good next spring. I know I'll be here.

Nice Daytona Photos Dave..... That silver 12R had an interesting chrome job; I don't know if I like the snorkel and plastic chromed, not enough contrast. The chromed wheels almost disappeared but it's interesting.
Is that Harry in the yellow t-shirt??

After some searching. After some Yellow pages surfing.....
( No word of mouth here, nobody else I know rides!! )
I discovered a DEFINITE "Harleys only", or ,
"NO sport bikes" at a few places.....
I did find some more than happy to do it...
What kind of $$$$ am I looking at??

Hey Dave, You are running the same setup I am going with this winter on my 12R. How about emailing me your map? Thanks, Ozzy zzx175@msn.com

That might be Harry... ... but that CAN'T BE HIS BIKE! It has all the fasteners and screws on it!
So Dave, who's the "power king" in the "nothin' done inside the engine - extrenal mods only" class? At the May Gap event, Harry was king with a 181 and 101, but I don't remember was the "fractions" were. Does your 181.4 & 101.0 "whack" Harry's or what?
