Once I understood that my tune was named with a different make, year, and model bike. I was good to go. That was the only confusion at the beginning. And yeah, I kind of got the vibe that they seem to think I should already know which we’ve all seen and that’s played out. I would say just either rename the tune for the person’s bike or give them a heads up that. Hey your tune is going to be listed as a different make and model…because obviously that’s gonna be a red flag for anybody who isn’t used to your specific process. People don’t know your process, that doesn’t mean they aren’t experienced. Overall it’s good so far.
Thank you

The gauge operation is a little clunky could definitely use fine tuning IMO allowing all the info stacked up on the page Is sooo much better than fumbling around with it for what seems like days then you have to double down and do it all over when bike is shut downOtherwise it’s on point
Developer Response
Hello, Thanks for the feedback! When you say stacked up, are you thinking something like a big list view that's all text rows or something along those lines? Happy to implement, just wanna make sure we understand what you're after! Are you having trouble with your gauge settings not staying when you reconnect to the bike or restart the app?

I’m happy with the way my bike ran after the first auto tune. That being said, my connection got lost in the midst of doing my second “auto-tune” session, and I had to mess with my dino jet app a couple times to get it to not be messed up, but I got it all figured out. I’m pretty pleased with the app in general though that being said. I’m also sure that either DynoJet or Fuel Moto would have come to the rescue if I wouldn’t have been able to figure it out myself.-Colto T

Being the first tuner on my first bike, I did not have any expectations just curious how it would work out. This product and application have been a night and day difference in performance. I would recommend this to anyone especially if you want to minimize the amount of electric devices on your ride
