FP3, nothing on the market is as easy to operate. Pick a map or if you need to; use the auto tune feature. Flash the map and you're done.

 

The FP3 won't work with his 2012 FatBoy.

 

Are you sure about that?
The V&H website says it will work on Fatboys '11 and up...
Look here under "Fitment".

Compatible 2012 Models:
FXDL Dyna Low Rider (Japan only)
FXDWG Dyna Wide Glide
FXDC Dyna Super Glide Custom
FXDB Dyna Street Bob
FXDF Dyna Fat Bob
FLD Dyna Switchback
FXST Softail Standard (Australia only)
FLSTC Heritage Softail Classic
FLSTF Fatboy
FLSTN Softail Deluxe
FLSTC Heritage Softail Classic Shrine, Peace Officer, Firefighter
FLSTFB Fat Boy Lo
FLSTFB Fatboy Special (some international markets)
FXS Blackline
FLS Softail Slim

 

I have the FP3 on a '11 Fatboy lo. Works great. Autotune might be a gimmick or might just take much longer than expected to dial in. I keep changing parts so I can't completely knock it, but I still have some decel popping after running auto tune for a few hours. You can mess with most of the same values as the PCV so if you have any tuning know how I'm sure it would be much easier to quickly solve small issues with the canned map.

 

so who is right?

 

I stand corrected. I went to the link mentioned above and it states

"Fuelpak FP3 2014-2016 Harley-Davidson*"

But then when you click on more info, and then the fitment button, it does list the 2012 Fatboy.

My apologies for the misinformation.

 

no apologies needed, just glad to get much advice... so which is the better buy

 

Said it a "bajillion" times on here, one of the cheapest/most economical/easiest tuners out there...Dobeck Performance: http://www.dobeckperformance.com/

I upgraded from TFI to EJK on my 09 FLHX and am thinking about the AFR. Great bunch to work with and they support military/police/fire active duty & retirees.

 

how do know which one is the right one for me, I have no idea what bypass is

getting confused by the second, lol

 

fp3....
