Then if this tuner is undetectable...thereby eliminating the worry of voiding one's warranty, why at the top of the product page you posted does it state in big red letters "Warning: The product is intended for "Race Ready" vehicles only" and that links off to a disclaimer about violating the ARB/EPA standards. lol
Just curious.

Not every one of them. Some, like the S&S MK45, proudly advertise that they're EPA-compliant. I will agree that most do, but then again, most probably aren't EPA-compliant.

Can you say for certain whether there is or isn't such a field, and whether your reflash accounts for such things?
Guy in the OP has already had his motor damaged by sumping, so -- any risking of warranty seems unwise.

Yes. That's my point. The ones that say they're not EPA/arb compliant could void your warranty. That's what I understand about aftermarket tuners.

Talk to PV or TTS and ask them to guarantee in writing that their maps are undetectable. I bet you wont get it.

Sorry, but this in not correct. Per a service manager, its true that a TTS or PV will reflash back to the stock map and configuration. However, there is a counter in the ECU's protected memory that records the number of times the ECU has been flashed. A reflash to the stock configuration does not erase that counter. So, as someone said before, say the ECU shows six flashes, and MOCOs database shows only two by Harley, then they derive that its been flashed by an aftermarket tuner. Think about it. Why would Harley create an ECU that controls most every workable function on a bike and not build in a way to tell if their ECU software has been replaced or tampered with?

You believe what you want. Do you have a M8 bike and a TTS tuner? Have you tried to know for sure?
I have the above. I have had warranty work. Nothing said about ECM flash count.
Also, so what happens when a dealer flashes the bike, and it doesn't take right and they have to re-flash the same flash? Flash count will go up.
I know this happens, ever updated your radio? Some times you have to do it a couple times for it to lead right.
Nice thing about using a real tuner and a good head pipe vs HD neutered crap is you get real power where you need it. I have raced HD Stage III CVO bikes with my CVO, all I have is a Fullsac Exhaust and tune. They cant beat me.
Give it another year, and Ill add a good cam and get much better power, just wont do cam now as it would be to hard to go to stock if needed.

And that is a surprise?
HD is more known for cutting cost and quality than implementing the best they cam.
Compensators have been a big issue for what, 10 years or more?
Failing lifers in 110's have been an issue for 11 years
Hydraulic clutch issues since 2012
The list goes on, heck they have had over 12 udates for the infotainment system since 2014 to try to fix all the bugs, which there are still some.

Ya, I can't see where a piggy-back tuner would leave a trace either.
When you flash the ECM though, that is a whole new ballgame.

If it comes down to selling one of my bikes, the rideable-computer ('15 Limited) will be the one out the door - no question and no regrets. No more new H-D's for me, either.
My '94 Dyna's the keeper! It DOES have a rudimentary electronic ignition, but that can easily be replaced (by me) with points and condenser if/when it fails.
The MoCo has not only shot itself in the foot, it's blown it completely off with strictly enforcing the "no non-approved mods, or else" bullshit, since most folks, at least on this forum, don't seem to be satisfied with these bikes in factory-stock configuration. Plus, apparently, if you do the "Factory-approved" hop-up mods, then you increase the odds of sumping and other issues if you try to actually use that extra power that you paid through the nose for.
Screw that!
