Not much help but I am planning to do my first auto tune this weekend. I had a small user error issue on the install and the guys were great at getting back to me via the email app. Maybe flick them the question (will take overnight for them to reply).

Good luck.

I have experienced exactly the same as you KC. I communicated with V&H and they replied saying that there was little benefit to be gained by doing multiple autotune sessions. So I ran in autotune for a few weeks over multiple rides and now I’m a very happy camper. However, now that I know what I know, in reality the FP3 unit becomes redundant after you have tuned the bike, unless of course you change or add something to the the bike that impacts the bike motor (intake/exhaust/cams etc.)! Seems we paid a lot for something that might only be used once. I confess that I thought I was buying something that would constantly be trying to optimise my tune, but sadly that’s not the case. I’ll use a dyno and expert motor tuner next time. I have now removed my FP3 as leaving it attached brings nothing to the party.

BTW. KC, if you open the app (no need to be connected to the FP3) and go to the faq section it pretty much says everything you need to know. I contacted V&H because my bike felt like it had sand in the motor, not oil, it was so rough during my autotune sessions. One thing I noticed is a lack of “news”, last post by them was in March 2017, probably find that the FP3 will be obsolete soon and they will launch an FP4 for the new Milwaukee 8 motors.

I tried it a couple of years back.. each auto tune got progressively worse and richer mixture.. do once, leave alone.

Was wondering the same with the Power vision.  Have done a couple of tunes and to be quite honest I haven't seen $680 of improvement.  Runs quite rough on idle for a little while too.  Sorry didn't mean to change the subject from FP3.

That's good info.  I naturally thought it would be a good idea to auto-tune from a previous auto-tune map, but good to know it's not recommended.  I've also been reading about Dyno tuning with the FP3 and you're spot on with the software.  The FP3 will allow you to edit the same tables as any other tuner.  The reason Dyno tuners don't want to use it is because it won't interface to their Dyno equipment like some other tuners will.  So this means to Dyno tune with an FP3 would require the tuner to put in the values manually through the phone app.  Understandably they wouldn't want to do that.

Hey guys, I just fitted my FLHTK M8 with Vance and Hines Power Duals and Hi Output slipons and a Arlen Ness Big Sucker intake.  Flashed the canned map from the V&H app and it runs sweet.

I just finished running the autotune on my sled. I saved the first couple of sessions & then hit finish after the last session as the bike was becoming a pig to ride. Strangely enough the bike was worse to ride with the autotune map flashed & I went back to a canned map again. I will try the process once again but was surprised by the lack of results that others have achieved.

Two tanks of fuel is a good run and that map looks pretty good to me.  Did you make sure you finished the auto-tune, not just did "apply learned values"?  The map only fully gets applied to the bike once you do the "finish auto-tune".

Tried the autotune process again & still don't think it is any better than the canned map I started with. The other problem is the longer I ride in autotune the worse the ride becomes. It backfires & hesitates every time I open the throttle up & becomes a real pig to ride.

I run the TAB Autotuner on my Vrod, Plug N' Play, self tunes, all you have to do is ride.

Happy to report the custom tune has made her a happy camper again. It is nice & smooth to ride, which is predominately what I was after.

Hi Guys

Hey guys, just thought I'd pass on the great after sales support I got off Vance and Hines regarding the FP3.  I have the usual mods on the Ultra and looking to fit a Zippers Redshift 468 Cam, after looking at the list of cams for the M8 the redshift 468 isn't there. I contacted a Tech via the chat portal and told him mods and what I was wanting in the way of a cam and it was sorted within the hour.

as great as these "auto tuners" are Rob, you are leaving a lot on the table especially when throwing in an aftermarket cam.

I'm a big believer in Autotuning (especially wide band setups like PV target tune) but NOTHING comes close to an experienced operator spending a full day tuning each individual cylinder properly. 

Depends on your expectations of course. Once you ride a properly tuned V-twin you are converted IMO.

My plan is to install the Redshift Cam and use the custom MAP supplied by V&H, do 2 - 3 auto tune sessions, then using either a TTS or SE tuner have a dyno tune session and then upload that tune back into the FP3. This will allow me to keep using the FP3 which has some great features and also show just how good or bad the V&H MAP and Autotune was.

I'll contact V&H to see if what I am planning is able to be done. I thought the custom V&H map would be a good starting point for my tuner guy, the bike would be tuned on Dyno using the TTS, all I want is after the tune is completed plug the FP3 back in to use some of the other functions and if possible have a copy of the Dyno tune settings on me phone.

After speaking with V&H I can do the above if using SE Tuner but not the TTS.

V&H Tech said next month they are releasing software for Dyno Shops called Fuelpak pro which will enable Dyno tuning using the FP3.

Bit like having 4WD lessons in a Landcruiser so you can go bush in your Suzuki Vitara

I know I'm digging up an old thread here but this is similar to what I'm getting. Set the base tune for my stage 1 ran it for a couple of weeks then turned on the autotune fully expecting it to run shitty but while the auto tune was going was actually the best it's ever ran. I've finished it and re flashed the ECM but it's not quite running as good now as it was. Populated a fairly good chunk of the map and did plenty of varied riding. Will have another crack at the auto tune starting from the base map and hopefully get better results this time.
