User reviews

App

This app needs to be updated to include more tunes, more options, better interface with the module. Not a great app when compared to other tuners.

Needs more work

Honestly, I’m a huge fan of tuning my bike and keeping it under warranty. But, I expect more from a company who does so much research and development. I recorded a smart tune and after clicking the stop button I was not presented with a save tune screen and lost the whole session. Are you aware?

Junk

I have to pair and unpair everytime I get on my bike and try to use this. I was going to buy the auto/wideband tuner that HD makes to add onto this but since Ive had nothing but issues with this I’m thinking about going with a complete different tuner.

Frustrating

Drops connectivity often. Will not save recorded mappings. Only reason I didn’t give it one star was because I was able to program the canned Stage 1 tune.

If you like to waste money and get mad, this is PERFECT for you.

I bought my bike with this “tuner” already on it. I have had maybe 1 or 2 successful smart tuning sessions with it out of probably 15-20 attempts. Most of the time it won’t even start the smart tune feature or even allow me to flash a premade map. When it does decide it wants to work.

I usually have a good ride and when I’m done I’ll leave the bike running, hit the stop button and “save” the log. Well when i try to find the recording it doesn’t even exist apparently.

So to sum it up, if you wanna waste hundreds of dollars and make yourself mad everytime you try to use it there isn’t a better product out there than this. Otherwise, id recommend a powervision since you can actually tune your bike and it runs much better than it ever will on this junk.
