Just wanted to let those who are using the FP3 on their Street Rod they just updated the firmware to include both idle and redline RPM adjustments.
I personally lowered the fully warm idle RPM to 1050 (last 2 cells) and raised the redline to 9500. I should be able to ride today to test this out if it warms enough.
The idle adjustment feature worked great-1100 seems like the sweet spot. The redline adjustment......not so much. I moved it to 9500RPM. The bike wouldn't rev over 6500 no matter what adjustments I made. I even flashed an old tune into the bike and then back to the one I was running. I have an email into my CSR rep at V&H's. We'll sort this out.
I bought it for $365 during their cyber week sale. When Jamie went to install the canned tune he noticed it was for a Street Rod. He called me and said they don't have a tune for that model-only the Street 750. My tuner of choice would have to start from scratch. I cancelled the order. I am going to give V&H's a chance to get this sorted out. They are looking over my tune as I type this.
The FP3 tune I used on my Street 750 opened up the rev limit by about 500 RPMs. I didn't try to manually adjust it beyond that.
(And just to be the warranty nag, since you're both talking about 2017 models, just be aware that using the FP3 or PowerVision or any such tuning product will immediately void your factory warranty on a 2017 or later Harley).
My selling dealer has a don't ask don't tell policy with their customers. This was clarified with the service manager. I have dealt with them for years. He told me just don't say anything to corporate and they won't.
V&H's is still working on my tune. Seems they were very busy yesterday.
I'd be interested to hear any feedback from other users if they had issues with the rev limiter setting.
There was another user that is using a canned tune that said the rev limiter was set at 12000RPM!! I have asked if this was before or after the firmware update. I think the rev limiter may be an issue with others as well.
12 K ? I have images of flywheels bursting out of crankcases! That is some serious error.
The case for dropping the tick over RPM is a good one, I've never had a bike tick over that fast before. Any Street owners reading this, what is the Streets' tick over set at?
Can't say I have thought of adjusting the rev limiter. Going by S&S's graph on the Stealth Air webpage, everything pointed to the Street Rod achieving what they promised within the standard limit. What were you hoping to improve on Scooter, or was it a case of 'suck it and see'?
Every bike I have is tuned, they all go 1000RPM over stock redline and can handle it or the tuner wouldn't let it go that high. You just bounce off of it less. Plus, if it's tuned well you will make usable power all the way there.
These erroneous numbers I am hearing as well as how mine reacted is telling me that there is a coding issue on V & H's end. The person I was referring to that saw his redlin set at 12000 has not ridden the bike since the new tune was loaded in. I made him aware of my issue.
I have it set for an 8K rev limiter though never take it there. According to GPS I have had it up to 136MPH.
Seems I'm not the only one that has contacted V&H's about the update. Here is a snippet of one of the emails from my CSR at V&H's
"As my fuelpak manager brought it up to our attention that is correct. You are definitely not the only one. They're working on rolling out another update."
This was in response to me telling him about the fellow I was talking with on another forum. So, we sit and wait. It's no down into the 30's here for highs so I'm in no rush.
Hi Scooter/Phil
I am on the verge of pressing the button for S&S stealth filter and V&H fuel pak 3 for my street rod.
Revzilla will ship ( without fancy S&S cover, will get one made an painted to match the bike ) for about £435.00 and anything I may get stuck for in customs. Still seems to be cheaper than I can buy in the UK.
Question is, I read about issues you have been having Scooter, is it something you would recommend ? I am not interested in raising the rev limit, but would like to lower the warm idle as you did. Should I press that button for V&H ?
Hi Steve, how's life?
If you're just fitting these two and not the Grand National muffler, S&S have a graph on the Stealth page which will show you the gains you can expect. I personally haven't had any probs with the FP3, but then again, I've not bothered to try and adjust the cold idle. I have been running on the V&H map of standard a/f + comp muffler with baffle. I haven't bothered to autotune this as she run's fine, and I doubt it would result in any noticeable difference.
I'm sure Scooter will be along soon to share his woes! I think he said V&H were still working on the high rev problem but every thing else was ok.
Let me know how you get on. I'm quite curious to see what your bike's performance is like without the GN muffler.
I can still highly recommend the combo you are wanting to run but I would also recommend adding the S&S Grand National slip on. It is one quality piece and sounds great without being obnoxious. I left the dB baffle in place.
The ONLY issue that V&H's is still trying to work out is the rev limiter. With the previous update I was asked by the V&H's customer rep via the tech folks to set the rev limiter at 12K rpm to get it back to the stock 9K rpm. This has worked until they get the programming for the rev limiter deciphered.
On the idle control. This works. I have mine stepped from OEM down to 1100rpm as it gets to operating temp. IMHO 1100rpm has proven to be the sweet spot for a warm rpm.
Life great thanks Phil. I already have the V&H Competition slip on on the bike from new. So the tuner and filter are the next step. I will let you know how it goes.
There's probably not much between these mufflers in all honesty Steve, both manufacturers are well respected in the tuning/tweaking market, and V&H did manage to coax 100hp out of a Street!
Well, the other thing to remember about the FP3 is that using it will void your warranty immediately. When I first got my 2015 Street, it seemed like the FP3 was "the thing" to do. You got your Street, you got your FP3, you celebrated.
Since then, for 2017-2018-2019-2020 model years, the rules have changed, and using an FP3 on any of those bikes will immediately void your warranty. Not just the FP3 either, it's any aftermarket tuner; the MasterTune or PowerVision or any of 'em. I only bring this up because I know a lot of folks simply have no idea that the rules have changed. The EPA slapped Harley hard and Harley is now bound by a federal court-ordered Consent Decree to void the powertrain warranty on any bike that's been tuned with any aftermarket tuning product.
........ The EPA slapped Harley hard and Harley is now bound by a federal court-ordered Consent Decree to void the powertrain warranty on any bike that's been tuned with any aftermarket tuning product.
Wow, that's quite a draconian stance taken by your authorities . It seems completely over the top when you consider the pollution caused by China etc, what possible difference will a few thousand motorcycles make in the grand scheme of things?
Even more worrying is what happens in the US today, generally impacts Europe a little way down the line.
In general that's quite true, especially when it comes to things like an exhaust system or an intake.
But there is one thing that is very black-and-white, and that is the use of an aftermarket tuner on a 2017-2021 model. The dealer doesn't get a say. Harley doesn't get a say. It is required by a court order and a directive from the federal government that they MUST void the powertrain warranty immediately, if they have any knowledge that a non-EPA-compliant tuner was used on the bike. Period, end of statement, no ifs, ands, or buts.
And re-loading the stock tune doesn't help. I've been told the ECM knows that it's been tuned, and apparently it will "phone home" when connected to the digital diagnostic tools that Harley uses to read the error codes etc. There's nothing the dealer can do about that; if they don't plug in the tool they can't diagnose the problem, and if they do plug it in, the ECM will alert Harley that it's been flashed. Harley can't just look the other way, they're under mandate from the courts on this one.
Now, I guess you could always just go to an independent shop for your repairs, because the independent shop wouldn't have the Harley diagnostic tool, but then -- you'll be paying for the repairs anyway, so that's effectively the same thing as having a voided warranty.
Moral of the story: whatever else you do, don't use an aftermarket tuner on a 2017-2020 bike or you WILL void your warranty the moment you tune it. The Pro Street Tuner #4100008C is the only tuner you can use with a 2017-2020 Harley and maintain the powertrain warranty. And yes, that is black and white.
No worries, I'm good. I had this conversation with my long term dealer at the time of purchase. Went over exactly what I had planned with them with already knowing what you are talking about. Others? Your mileage may very.
Understood, and glad to hear you knew exactly what you were getting into. There's a lot of folks who don't, so I'm just spellin' it out so new owners know that the rules have changed.
