i have been running around with a semi stock map since i had the powercommander installed, and all though the bike runs pretty good, its deffinetly not tuned 100%, it stumbles a little off idle and smells rich, and when im on it hard black smoke comes out the pipes (a rich condition)

im gonna get it tuned, i found 2-3 different tuners in my area that are reasonable (a harley dealer said they would tune it for $425 [B)] ) two shops said the would do it for $250, which i can afford, both seem knowledgable, but what else can i ask? what do i need to know?

I looked on dynojet's website and looked for certified tuners for the PCIII. I have to ride about an hour to get there but I think it should be worth it.

http://www.powercommander.com/centerbystate.shtml

Here's what they say:

Power Commander Tuning Centers can optimize the fuel and ignition mapping for your motorcycle. They can also develop custom maps for special applications. All "Dynojet Approved Power Commander Tuning Centers" have the latest "state-of-the-art" Dynamometers and testing equipment. This includes the new Dynojet Model 250 Load-Control Dynamometer and the Dynojet realtime Air/Fuel Ratio module. In addition, these shops have successfully completed the Power Commander technician training course at Dynojet Research.

It doesn't mean you won't get a tech with "rectal-cranitis" (head up his butt) I just figure your odds of that happening should be less.

My wife's cousin's Husband is a Dyno tuner, I can get a hold of him tonight and find out the particulars if you want. He's top of his game and well known by the Dyno guys as soon as I get my V-Bak I'll be making a trip to Denton to have him tune my bike, even though he's a Harley guy [/emoticons/emotion-4.gif]

I have had my bike on 2 different dyno's & got 3 different sets of readings.I dont know what to believe as far as the #'s go.I do know that I do have friends with car dyno's & they say depending on when & how the dyno was calibrated you can get different #'s from the same veh. car or bike. So as far as I am concerned if you want a dyno queen,build a dyno queen ! If you want a bike to run.Just talk to the guys on this site & go for it. quote:Remember.We dont burn rubber,we make it screem for MERCY!![/emoticons/emotion-2.gif][/emoticons/emotion-2.gif]

My thoughts:

Every dynoshop/dealer has the best dyno ever made and the best trained tuner period.

Go in and talk to them. Get the guy who's going to tune your bike on the phone, not the service writer. If you can stop by and talk to the dyno operator all the better.

Your bike should have at least 2 identical overlaping curves to prove repeatable power measurement before any tuning takes place. That means at least 2, if not 3 or more, baseline pulls. So ask them how many baseline pulls they do. If the guy can't answer that...run, don't walk, away from that dealer.

They need to have the ability to hold your bike at agiven RPM. That means an Eddy current brake (or water brake). DJ 250 and 250i qualify. Older 100s, 150s and 200s qualify only if upgraded with the eddycurrent absorber. Superflow Cycledyns almost all came with eddy current brakes, but some are inertia only. Factory Pro EC997 and Dynostar 70s are also eddy current dynos. Land & Sea makes a waterbrake chassis dyno. If the dealer tries to bullS$%^e you about being able to map EFI on an inertia only dyno...leave.

They also need exhaust gas analysis. Wideband oxygen is OK and easy to use. 4 and 5 gas analyzers are great, but hard to use and tech to techs, so it's also possible to get someone who has some good equipment, but does not know how to use it.

Ask if they'll give you your beforeand after plots (yes they should!) and if they will show you what they had to change in your map and why. That should also be a yes.

A lot of people have dynos now and see it as a big money generator (it's not all that big unless you get a LOT of customers). If you can find a place with an enthusiast operating the dyno you'll be in good shape regardless of the brand of equipment. He should want to tell you everything you want to know and more. If not, look 'til you find him!

Good luck. A good dynotuner is great thing to have nearby.

Everyone is the best, just ask them! No one is going to tell you they are average and then ask you to give them $250 or more. Talk to a lot of people in your area, and listen to what they don't say. One guy on this site, picked a specific tuner, because a lot of racers used him and they thought he was good. But what really swayed him, was that no one had anything bad to say about him.

both shops said they would let me watch the stcok (base line) pulls, and they would allow me to see one of the final pull, both said i couldnt be in the shop the whole time due to insurance regualtions, but i could stand outside of the shop if i wanted (where i can see, but its pretty hard with everything in the way, i would be standing, and in the sun)
