power commander tune
Ok guys, didnt find what I was looking for while searching so Im gonna ask. Ive got a 2006 Night Train with V&H Big Radius pipes and screaming eagle air cleaner. I down loaded the tune from Power Commanders webside to my PCIII and everything went smoothly. But while riding the bike it doesnt seem as smooth at cruising speeds, like theres a slight pop in the exhaust tone that wasnt there before and at low speeds seams a little jerky, and at idle it smells rich. Is there another tune that you guys know of that might work with my combo better or should I just play around with different tunes.

Why did'nt you have Jaime at Fuel Moto load the map before he set it too you? If you have changed equipment since your original map & your downloaded map is not working for you call Jaime. You could always send the unit back to him & have him re-map it for you.

How do you know he got it from fuel moto? just curious because they only give free maps to those who have purchased from them..
And if it doesn't feel like it's running right, you have the option of reading through the PC instructions to try to tune it yourself (jacking it up, running the bike @30mph etc etc).. or find someone local to tune it for you. can't go wrong with a good reliable tune

I didnt buy it from fuelmoto, and theres a big bore kit in the near future so I was kinda waiting on getting a good dyno tune then, I think maybe Ill try a new tune with a different air cleaner set up etc till I find one that seems a little smoother or something.

Well, a decel pop out of the exhaust means a lean condition which is a surprise with a canned map to me. Uneven slow speed cruising also indicates a bad fuel AFR. Those are both traits that mine had before I went to a TMax.
A dyno tune will definitely help as long as you aren't changing loctions or experiencing wide temperature changes (usually getting in really hot weather will create some problems) once you have your AFR set. A PCIII USB has buttons on it that you can use to change between preset map conditions. You can dyno the bike for mileage/performance compromise or just performance. You can make adjustments from this base map (they are a flat percentage change I believe) by pushing these buttons but I couldn't easily reach mine, so I went to an autotune setup with O2 sensors and I ain't looking back. HD should have never released an EFI bike without wideband O2 sensors. Period.
You are wise to wait to do a dyno if you are going to make major changes. However, at about -8 mpg at $4 per gallon, you are spending about $0.20 per mile in lower fuel mileage with a canned map from my experience with my PCIII (from 36 mpg to 44 mpg). Say it's $0.15 a mile. In 2000 miles you have paid for a dyno in fuel mileage.
I was operating under the same fantasy about a 95 kit when I bought my PCIII right after the bike was new. I haven't installed the kit yet and I'm at 55k and counting. I got a dyno at about 10k. Once I got into the cam chain tensioner mess I decided to wait to do the whole shebang at once when I roll up to 75k. New top end, cam, tensioners, etc. I don't think I will need a dyno with the TMax. I also have no plans on buying a new Harley so once I decided to keep this one and make my own improvements instead of being HD's guniea pig, it changed my whole perspective.
Just my 5 bucks... at about $0.02 a word.
