Power commander, worth it??
Hi guys,
I'm looking for input and advice. I've got an 05 heritage that I've had bored to 96" heads have been flowed, crane cams, performance machine air cleaner, Samson true duels (not a good choice for power I know) and the equivalent of a arlen ness cheap shot fueller.
Now my question is, I'm looking at putting some more money into my bike, is a power commander going to give me much more? She pulls like a train but wondering whether I'm getting the most out of her.
Thanks in advance.

No. Get the PowerVision if you get something else. The PowerCommander is a piggy-back system, similar to what you're using now. These tend to be a lot less precise. You're basically tricking your ECM into thinking the 02 readings are different than they actually are.
The PowerVision, on the other hand, loads a completely new map onto your ECM. This addresses the problem right where it lies. Not to mention the auto tune feature, meaning you can tune your bike yourself without paying $300+ for a dyno.
I'm a fan of the PowerVision.

Lots of builds running with PC V's. It is a piggy back setup but nothing like your fueller. Your Arlen fueller is fine for stage 1 and maybe even bolt in cams. My cammed 88" has been running great with a DFO, same as your fueller for many years.
With headwork something like a PC V or PV would be better. Or TTS. Are you planning to have it dyno'd? IF so, ask your tuner what they prefer. Also, keep in mind that some of the responses you are getting about PV, are those with later model bikes and o2 sensors. Call Fuel Moto and ask them the differences and what these products can and can not do on an 05. When I checked on the PV a couple years back, their were limitations on 04's or 05's and earlier bikes. It would work with 06's then. Maybe this has changed.

I have a powervision and use it on both my '12 Limited (has O2 sensors) and my '03 Heritage (no O2 sensors).
The powervision will do everything with the '03 it will do with the '12, except for the basic autotune feature because of the lack of OEM narrow band O2 sensors. So you're limited to flashing MAPS or adjusting MAPS without the help of basic autotune. However, I know from experience that any MAP from FuelMoto or DynoJet will be better than an HD download.
The other limitation, is that Fuelmoto does not have a lot of support to offer, in way of fuel maps, for the pre '06 bikes. FM didn't have a map for my '03 with the current mods (HD big bore kit/ exhaust), but DynoJet took the HD download tune, and was able to dial it in. It now runs great.
Jaime said he would be able to "get me real close" with a map when I switch to a Woods conversion cam in my '03.
I am considering buying the Auto-tune Pro module, then I can dial in the '03 myself with wideband O2 sensors...
The beauty of buying from FuelMoto is you get both FuelMoto AND DynoJet support!

This is exactly the stuff I need to here, my only issue would be finding a tuner that offers anything other than the power commander, I'm in the UK and we're honestly so far behind you guys when it comes to Harley's. I'll definitely get it tuned on a rolling road,
is this sort of tuner gonna make a noticeable difference?
Thanks guys.

Depends.....
You did a lot of work so I am assuming you have had it tuned by somebody/somehow after all that work...?
If it runs great and you're happy with the it, just ride it! You can spend a lot of money chasing a few extra horsepower, that you may not even feel.
If you haven't tuned it since you did all that work... I'm not sure how it could be running so well on an OEM tune. I would suspect that you are pretty lean and I would get it tuned..... ASAP
Obviously, a GOOD dyno tuner would be the best tune you could get. Good Dyno operators are not available everywhere in the states, not sure about their availability in the UK. A GOOD dyno operator is a blessing, a bad dyno operator is a curse! Choose wisely....
I believe a MAP from a good tuner (like FuelMoto or DynoJet) would be more than acceptable for a non-racer who is just a street cruiser. Being able to further dial it in to your exact bike with some sort of auto tuning, obviously would make it even better.
Since your bike is before the factory O2 sensors, you could spend the money to get self/auto tuning capabilities, but I think you'd be approaching $1K no matter what tuning hardware you choose.
A lot of choices that will be based on your needs, your wants, shop availability, and pocket book.
Good luck....

My guy that did all the work tweaked the Ecu as Harley would? then put the fueller on it, it absolutely flies just feels as though it wants a bit of fine tuning low down.
My guy doesn't have a rolling road which was making me think it may be worth doing.
