Great app but needs to work with Apple Carplay

The app works great. My only request is to get it to work with CarPlay. It would be nice to be able to switch maps through CarPlay as well as use the gauges and be able to do data logs all while using the app through my radio.

Apple carplay

Hello developers at ecutek,

I truly appreciate the tuning platform you guys provide on Subarus,

BUT can you make it work on apply CarPlay? Make a widget or something. so that I don’t need a phone to see the parameters, I can just look at it on my screen!

Don’t change the background picture of your dashboard

Ts just kicks you out whenever you try to change it or get rid of it so you can never get rid of it annoying asf

Super finicky

Literally nothing is easy with this POS - constantly get refusals to flash, citing nonexistent problems with gear in parking or interior fan, super finicky about battery voltage, as in literally on jumper cables, battery at 12.5-13v and still won’t flash, zero transmission logging, a pain all around.

Also, it’s impossible to find a good ecutek tuner, none of the shops will do it if they didn’t build your car themself, so good luck if you ever do any of your own work. Use Motec or something else if you don’t hate yourself.

One Flaw

I’m not sure if this is a flaw or not. I really wish ECUTek would go through whatever process needs to be done for the app to work with car play. Lock out functions while the car is moving if you have to, my music folders with iTunes does that. I want to display my dashboard on my cars screen, without the need of a stupid carlink box using my phone as a hot spot. I really don’t understand how gauges wouldn’t get approved.
