Hey, i'm sure this question has been asked/answered many times, but i've done a few hours of searching and reading and can't find a good answer.

I just added V&H Big Radius (2 into 2) pipes to my '09 Fatbob and am thinking about adding a SE Heavy Breather. I know that I need to do something to the ECM to adjust the air/fuel mixture.

I assume that buying an aftermarket tuner such as a PCV or Fuelpack would be a bit more $$$ than just having the dealer do a remap.

If that's the case, what would the advantage of buying a tuner be over just having the dealer do a remap?

Thanks for your input.

 

Some bikes and mod combinations respond well to the dealer download, some don't If your bike doesn't perform well after the download, you are out $150.00.

A PC-III is available for under $300.00. There are many canned maps available to ease tuning of your bike. The units are versatile in case the canned map isn't exactly what you need, adjustments can be made. Later down the road, if you do motor work, the PC-III can be further adjusted to accommodate the mods.

Fuel Moto offers great customer service and will send you a PC-III pre-programmed for your particular model bike and specific mods. If you need a different map later on, they will hook you up.

 

I would say the download is a waste of money, but ultimately it's your decision. Aftermarket fuel management can fail... the download could serve as a fail safe if that happens on the road. One thing to consider, though, is I think that the power commander needs to be mapped differently if you have the stage 1 download. Someone more familiar with the unit may know better. If you desire the higher rev limit that the stage 1 provides, the new power commander EX has the rev extend built in. Make sure when you order one it's an EX with the rev extend, some sellers on ebay are not clear on which model you are bidding on. One things for sure, these things are definitely smothered up from the factory.

 

Dude, I’ve got the Big Radius 2 into 2 and Screamin’ Eagle a/c with the Harley remap from the dealer. Got it that way brand new. It runs like a bat out of hell – no popping on decal or any of that crap.

If you’re going to want to tune a few extra horsepower out of your bike then you might benefit from the PCIII or whatever generation it is now, but you’re not going with a 2 into 1, so I doubt that appeals to you much less are you likely interested in going beyond the Stage 1.

If you’re like me and you just want it to run right – then I can attest that the factory download is sufficient for the setup you are interested in.

I’m not expert on this sort of thing, but I had comments that the black smoke is what you want to see on a property tuned bike……. Here’s a video of my Bob with a little throttle:

I bought a Fuelpak for my Nightster with its Stage 1. It was a PIA to install and I had decel pop with it.

Thanks! I ended up going w/ the SE Heavy Breather w/ dealer stage 1 download. Bike was already at the shop getting some other stuff on it. Today was last day for a 20% off sale so i needed to decide. Should get it back this week.

 

Man, that's an all-profit sale.

"Here, lemme plug this gizmo in...hurp durp durp...three, two, one. There ya go! $150, please."

On the other hand, I'm probably going to do a Stage I on my Dyna and that'll be about it, performance-wise, so perhaps the full might and authority of a PC V isn't strictly necessary...

 

Had the same deal with my Nightster. I'm gonna spend the money to get my Street Bob done right. BTW, your bike sounds awesome.

 

The tuner will come in to play if your going to do other mods to your engine. The fuelpak well good for stage 1 will not allow you to dyno tune the bike later when mods are done. If you are just going to do stage 1 then the download will probably work the same as the maps from V&H or from PC.

This also throws into the mix that the newer models using the closed loop system and the O2sensors learns and adapts the mods of stage 1 without anything being done to the ECM.
