Yeah, that's ok. Do you have a tuner and if so, what kind? I saw lastnight that vance and hines is making the FP3 for 2007-2013 bikes now. I wonder if that would be better than the inline fuelpak?

But it certainly looks like a faulty tuning device....
I personally am not a fan of piggyback style devices..... If you plan on any other mods along the way, or it fits your budget, I'd go with the DynoJet PowerVision tuner. I use it on both my bikes, and it's a great piece of kit.
If you just want a piggyback device, give FuelMoto a call. I have not used it, but have read good things about their Micro EFI Tuner...

Good luck whichever way you decide to go... at least you now know what the issue was...

Possible o2 sensor issue
Well at least the cleaners didn't hurt anything, they were overdue for the O2 sensors anyway..... just consider it a maintenance exercise..

Piggyback devices are attached to the ECM and stay connected to the bike. They manipulate (in some cases imitate) signals from the O2 sensors to the ECM. It fools the ECM into running richer/leaner as called for by the device.
A tuner will flash the ECM with a new tune. It actually changes the map in the ECM. It allows the rest of the system to function as designed. The tuner can be removed from the bike after flashing the ECM, or some can stay attached as a secondary set of gauges.
I use and am most familiar with the DynoJet PowerVision tuner. It will not only flash a new tune to the ECM, it will allow for an auto tune process, using the OEM narrow band O2 sensors, to further dial in the flashed tune. It can also be left attached as a gauge. If you get it from FuelMoto, you will get lifetime map support from FuelMoto AND DynoJet. If you ever get another bike, or switch bikes, for the cost of a dealer download ($199) you can get another license for the PowerVision and then use it on the second/new bike.
I currently have a PowerVision from FuelMoto, it is attached to both my bikes and two close friend's bikes. That's 4 bikes that I can remap, auto tune, check for codes, and make adjustments to almost any ECM controlled parameter.
Good luck with the project... once finished, it will be worth it... enjoy the ride!

In very simple terms:

ya, after all what they do is tell the ECM that the input orders went through correctly or hey they did not and we need to make a quick correction. better just to cross fingers that the map is perfect and no need to measure the actual results.
why take your finger off the start button after the engine starts?

Before you start calling people out, educate yourself, then come back and contribute positively instead of spewing garbage.

Did you get the map for the FP from the site or did you just tale it as offered and change nothing. If not, let them know what your setup is, might be you can get a better map.
PCVs and before that PCIIIs, and for that matter most of the piggy back solutions run open loop without O2 sensors. I ran my Honda open loop with a PCIII and run my RGU open loop without issue. I have no idea if that applies to your model though.

thanks for your concerns. before you blow steam you should know who you are talking with. I am educated in flash tuners, familiar with fuelers and those that are in between. perhaps you need the education. do some reading and see how many issues became attributed to piggy back tuners. Narrow band O2 sensors have been accepted to feed back up to date information in order that the ecm can make adjustments for the input. piggy back tuners? have a map generically designed very similar to the dealer stage 1 flash. There are no guarantees that a canned map is performing the best for your ride, or that it performs the same on two identical bikes since you are not using the feedback from the O2 to find out. The popular piggyback tuners fooled the ecm into allowing more gas across the board by altering the signal from the O2 or by adding a dummy O2 at the end of the wire to the O2.
BTW, flash tuners are not for everyone because most will not take the time to tune with them and just use them to flash the starting map.
end of rant!

It's really funny with EFI and the arguments about a very precise mixture how we ever got by with the simple carburator. Yet we did, and to ones bike blew up.
