Needs CarPlay

Great app. If it had CarPlay it would be perfect.

Great app but should support car play

The feature set available is great and vey useful. But if this could be a CarPlay app it would get 5stars

Good but limited

So, first, when you install the module and turn on your car, it makes you dump the existing tune—so, if you’ve spent a bunch of time on the PC tweaking the settings, I/Os, or anything, that all goes away.

With my install (Factory Five Cobra w/ G2 Coyote) I have a check engine light wired for output 2, and my fan set at output 4–they were working with my old map.

Unfortunately, it’s only letting me set the fan output but not letting me set the CEL output. So, I’m sure I’ll be spending some quality time with tech support.

I also have the Terminator driving my tach, which isn’t working now. So, I’ll need to figure that out too.

I’m sure there’s ways to make all this work, and with a brand new app, you expect some room for improvement.

I would love to see the app modified to download the existing map to continue working from. For everyone with an existing functioning tune, it’s crazy to force the deletion of it just to use this module.

Aside from this gripe, it’s a really cool setup and using an iPad to tune/program is so much more convenient than using the tiny wired touchscreen that you have to use the stylus with.

Once we see some app updates, I expect it will get better.
