I have a 2019 TriGlide and was told by the techs at the dealership, where I have done business for many years, that I should avoid the aftermarket tuners. I have never used an aftermarket tuner for this reason. I agree that there is not much sense in going looking for a problem if you don't have to. My concern is that, when traveling, heaven forbid, that you have a ,mechanical failure and the local dealer says "no way" and you are stuck in the middle. I will use slip-ons and everything else stock until we put some miles on the bike. You have to remember that the parts vendor does not get the headache, you do. I am not willing to take the risk. Just my thought!!

 

The bottom line is if you change your mufflers HD is now voiding warranty over them! There newest claim is that they say, must use a new calibration for mufflers and you do not have a Street Tuner installed so your powertrain warranty is now VOID. If you look in the SE catalog the mufflers say "ECM Calibration Required". Why your dealer buddy may look the other way that doesn't help much when your out on the road.

 

Not necessary to go to court initially, but you may need a lawyer. A report to the FTC and a complaint on a denied warranty, is needed. The FTC is not answering very many inquiries into this dilemma as of now, though I have gotten a few answers. Interesting enough, as far as the FTC is aware, no one has had a warranty claim denied for an after market tuner install since the EPA agreement. I have seen on some Harley forums where some have claimed to take their modified tuned bikes in for repair and all covered under warranty, is it BS, is it luck, is it willful ignorance, does Harley know they would violate the Mag-Moss?, who knows. As I already stated SEMA will have a lot to say about this as well, if you don't understand SEMA's involvement. then you probably shouldn't be in on this conversation.

So to answer your question, there is absolutely no way 50 state/EPA exhaust parts can in and of themselves void your warranty or your powertrain warranty, it may take a court fight if you use non-EPA parts, but, in most cases I would think the Magnusson-Moss would prevail. (Except CA and maybe some other states)

As for tuners, the same applies, 50 state/EPA and they have to warranty. Not sure about motorcycles, but some car tuners state will not void your warranty and give the number to call the FTC if a dealer refuses warranty work.

Anything a dealer tells you get it in writing. If I get a new exhaust and hi-flow intake, I will probably check into a dyno tune at the dealer and see if they tell me it keeps the power train warranty intact.

 

Actually it might.

 

Harley just resent a reminder to dealer that it blocks VINs of bikes that they are made aware of and voids Powertrain Warranty at end of March. Powertrain is an an extensive list of components and the warranty on it is what, 5 years? If the dealer doesn’t plug into the Digital Technician then the mothership will not know what you tuned with. I was told by the person in charge of Warranty at a dealer that eventually, your bike will likely get plugged into a DT at some dealer. If you travel and have a powertrain problem and a TTS or FP3 or whatever tuner do you have the cabability on your bike to revert the tune? And I have been unable to 100% decern that the DT can’t tell you retuned it. Anyone out there with definitive proof Harley can’t tell you retuned and then detuned? The bottom line is Harley knows the Hot engine in M8s will burn up and vastly shorten the lifespan - hence voiding PT warranties saves them millions potentially. Rerouting the gases coming out and being fed back into your combustion chamber is probably another powertrain void, but it’s probably something that will make your engine run longer and better since it was not designed to burn oil.

I rode about 8 miles yesterday in mid 70’s temp, 4 various length stoplights. Got off my ‘18 RK and my jeans butt and back of upper thighs were soaked with sweat. ‘15 RK didn’t do that, ‘17 RG didn’t do that quite to bad but was also hot as hell. If I sweat that much riding 8 miles, how much am I losing riding 400-600 miles? Dehydration is a killer. One major sign of dehydration is blurred vision, it comes on very quick. You can imagine the results of bad vision on accident ratios. Basically, the EPA is willing to kill people to keep the bikes at X emmissions.

 

Sorry if this was asked. I have the pro tunner and have already did the auto tune, however with on 15 min run time it dose not give you much time to test. Can or has anybody done this? Set it up as auto tune on a dyno however run it on the road with the old lady holding the tablet so it can fill all the different cells. This way your can hit more cells?

Thanks for the input.

I mounted the tablet on the bars, it's not real safe but it's doable, no other traffic or speed limits would be good as well.

 

in some cases, warranty will depend on the dealer.
I know a few dealers that will install the powervision, any V&H parts won't viod warranty. they'll even sell you S&S parts and won't void warranty, but I think it comes down to who's doing the install. If dealer installs anything, you should automatically be covered regardless. They sold the parts, they did the install, should be a no brainer. INstalling parts yourself, well, you mess up its on you, know what I mean?
