Question about FP3 Auto Tune
I've been reading a lot of good things about V&H FP3 tuner. Especially its' auto tune feature. From what I've read, you load a map to start, then run one or more auto tune sessions to achieve an "optimal" tune for your bike. Sounds straight forward enough.
My question is: if you're going to run through a few auto tune cycles, does it it matter what map you start with? Will you always end up with the same "optimal" map?
For example, I don't have VH components. No worries, I can load a generic map based on a generic exhaust. Or I can pick a VH setup that is similar to mine in terms of slip on diameter and baffle type. If I load one of these and auto tune will I end up with the same tune as if I chose the other as a starting point and auto tuned?
Please don't reply saying FP3 stinks, or telling me to gets PCV or anything else. I'm not asking for opinions on what to buy. I'm asking for knowledge on how the FP3 actually works. If you know, please enlighten me!

There have been recent threads on what "autotune" is and does ...in general it's the same process for any of the flash tuners.
There are also recent posts specifically on the FP3 and whether to autotune or not seems to be debatable.
Have a read of them and see where you get to

The basic answer is no. Using different calibrations is going to have different results. Is the timing the same for all calibrations? No. Are you looking at a 044 level cal or a 009 level cal? There are different things in the back ground. What else is different in the back ground?

Love my FP3....
I recently added the FP3 {Map/Tune}, to my 2010 Dyna SG. I had previously added the V&H 2 into 1 Propipe exhaust and the Screaming Eagle high performance air cleaner came with the bike.
Sure feels like significantly more power, allegedly about 7 HP and another 10#'s of Torque but I have not put it on a Dyno to check and frankly Scarlet...
The biggest change was immediately apparent in the dramatic reduction of engine heat. Probably lost about 30 degrees. The inside of right boot used to get pretty warm {I ride here in southern Arizona which certainly exacerbates the engine heat with our 100+ degree summers}, but now it is noticeably cooler. Even my bride noticed immediate improvement.
Clearly with the Propipe and SE AC the bike was running lean and the tune riches it up a bit. Surprisingly my mileage has not seemed to suffer. Still getting between 47 and 50 depending on how hard I roll and/or if my bride is riding along.
Oh and yes it sounds just a tad bit better with a throatier roar.... but then, that's just my humble opinion. Best $300 I've spent since the $650 that bought the Propipe.

I think I might have the answer you're looking for... I put a Fuel Moto breather on my 2016 King, along with Rinehart Slimline Dual exhaust.
1. I first loaded a V&H Power Duals header with V&H Power Rounds as per the folks at Vance & Hines, because as you know, they don't load anything other than V&H stuff to pick from. Loaded it and it ran okay, but a bit rich, so I autotuned it for a tank and a half. After I flashed that load to the setup above, it appeared to run a bit rich and was popping some.
2. I then loaded the Generic Aftermarket load on it and immediately started the autotune. During autotune on this load the bike seemed to run better all the way around, although again just a tad rich. After two tanks in autotune I flashed this load and now things run much better. Better than the load on item 1 above. It still seems to cough a bit with throttle increase when cold, but not much, and when warm it runs good.
Hope that helps.

Check,
That's what I was wondering. Thanks for sharing that. Based on other info above, it all makes sense. If the tuner had a super computer inside, maybe it could auto tune every table and every value, at all RPMs, all pressures and all throttle positions. But that's not possible, of course. Which is where my question comes from. It's interesting to hear you having better success with a generic setting. I guess that makes sense, too, because not all pipes are like V&H's. This is quite an interesting discussion!

Which comes back to basic tuning advice for any of the flash tuners ...which is what I hope you might have read
The confusion with "Autotune" is that it does no such thing ...it only tries to remap the VE tables, which may only be the tip of the iceberg because different maps may have different other settings, or other settings may need to be changed to optimise your tune ...which you can get into if you know what you are doing though.
I don't know where you read that the "Autotune" feature was one of the good things about the FP3, but all of the flash tuners have an auto tuning feature, and as I said there have been a couple of posts recently about it making things worse so just wanted to make you aware of that. Unless it has been fixed since I used mine, it did not "autotune" the 0% throttle position column ...which I always thought was a bit, strange.
I suppose it depends on how close/good/optimal/whatever you want to get your tune. Check6 sounds as if the warmup tables could need a tweak, for example.
- "Autotune" because a map developed on one bike is not necessarily going to be as optimal as that needed for yours
