How to_ 2021 YZ450F PowerTuner App File Downloads

Found a glitch in the Yamaha Power Tuner App in IOS. Shout out to BMLO Productions for the clips for my new intro.

I just got a 2019 last weekend and it had this installed. Been trying to figure out how to get connected (password on back of ECU) and upload maps (had to add a new machine got errors trying to add to existing machines). Ran into some roadblocks but was able to get it figured out. I did it the 2nd way where I emailed the tune to myself - so it worked no problem. I did not use the share command. I actually copied and pasted the shared file between machines as I recall, but I need to check again. It was my first time successfully downloading and uploading to my ECU so I was just happy to have done that. (Old guy so not that tech savvy). Ready to rip - once winter breaks...

So can i download the 2021 maps even if i have the 2018

Unfortunately I have no experience trying to load maps from one year to another but I would not recommend trying it. The engines are likely different enough that it could damage the motor if you can make it work.
