What a PITA!
I'm comparing this to what I have previously used (V&H FP3) on other bikes. There are no instructions inside the box, just a QR barcode that brings you to the website. Beyond that, you need to figure it out on your own. I found a tutorial on how to install which wasn't accurate as it states you can open an account through the app. That is incorrect, you need to click on the 3 dashes in top left corner and open account. Next, the link on their website to download the Vision Power app doesn't work, you get an error. Once I was able to download through Google Play and I verified my account through an email (needs to be done before you can use app), then I was able to scan for the PV4. Next, you need to "Read" the ECU as if you don't, you will lose your stock settings. Once I was ready to flash, it asked if I wanted to use the "Token" to flash the ECU. What? Evidently, you receive a token when you purchase and any future changes, you must purchase a token, I think? TBH, this was a very frustrating process as their instructions and steps are not very clear. There aren't very many tunes for my bike, maybe 4? The only positive is that the tuner is not VIN locked and you can flash other bikes. I heard the FP4 has major issues so, I went with this tuner. I noticed that it started up and idled better. Will update after I ride it a bit. At this moment, not impressed with this tuner.

Go to the source
Order from the manufacture directly. Received the wrong parts 2 times and couldn't get any help from the manufacturer because the product wasn't ordered directly from them.

I rode 18000+ km on a stock 23 Softail 107 and am very aware of how it performs. Added slipon mufflers without any tuning and noticed a slight improvement in performance. Now have 20000km. Decided to do a full stage 1 by adding a high flow air cleaner and this frustrating PV4 device. Air cleaner install was simple and easy. First time booting up the PV4 all I got was error messages. Some time later after rebooting and resetting Bluetooth etc I finally got an error free connection. Flash the specific map and go for an 80km ride. Seat of the pants dyno tells me 2000 - 3000 rpm feels flat and lifeless now. This is the rev range I spend 99% of riding time. It was instantly responsive with plenty of giddy up on the stock tune. Feels a bit gutless now. The original grunty torque curve I loved has gone. Great, spend around $200 AU on an air cleaner kit, and nearly $800 AU for this dynojet paperweight that has made my bike run worse than stock. $50 worth of jets/needles, and an hour to install was all it took to do stage one carb tuning on my previous Harleys, always with positive outcomes. $800 (16 times the price) and a couple of hours frustration with this dynojet thing has resulted in a bike that runs worse, and instead of nice burbling when decelerating I now get random pops and bangs. Just got back from another 80km ride. The current tune has also created a dangerous stumble when moving off from stationary, twice causing me to nearly drop the bike. Right now I need to go back to stock tune and reinstall the stock air box and filter to get my original Better performance back, at least until I hopefully hear back from dynojet. Not holding my breath though. I do not recommend. Zero stars. p.s. I would not buy from this Amazon vendor again due to the slow dispatch and weird tracking.
