Bugs bugs bugs

Common Harley. Fix this. This thing is so buggy that it takes away the enjoyment of auto tuning. I am doing everything required: turn my Infocenter off, turn Bluetooth off on the bike…it still gets stuck every time. It takes multiple tries so get into auto tune session. Also, speedometer doesn’t work which is dangerous. I understand the rider aid being off but speedometer is important. I paid almost $500 for this thing. I would expect for it to work.

Garbage

Worst 400 dollars I’ve ever spent. Won’t connect, and when it does I get a litany of errors. Now it can’t read my VIN. Time for a PV4!

Frustrating

It works after a lot of wrestling and retries.
Needs improvement.

Absolute Trash

The inconsistencies you will have in connectivity will frustrate you beyond belief.
Just take it in and have your system tuned or buy a better tuner.
Very disappointing but consistent with Harley continuing to create trash the last few years.

App is slow and cuts in and out

App is slow with Bluetooth connection and cuts in and out so often I just shut it off, even with a good wifi connection & Bluetooth and with bike sitting in my house garage then tuning they say a couple minutes ha ! I would start the download process for the tune and have walk away keeping everything in close proximity and return after 30 minutes with out it being completely done , tried deleting app reinstalling, rebooting , at that point I’m frustrated and shut everything down ! Waste of money if you ask me !
