Ok app

I wish they could make the throttle sensitivity available for everyone instead of depending on the tuner to make it available. It’s an unnecessary restriction on users.

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.

Do I need to buy anything to use ECU Connect?

Yes, to use the full features of ECU Connect, you need to purchase an EcuTek Bluetooth Vehicle Interface from an authorized EcuTek Tuner. The app itself is free to download and use, and includes a demo mode if you do not have the interface.

What can I do with ECU Connect?

You can program tuned files from EcuTek Master Tuners, adjust RaceROM features like Launch RPM and Traction Control, view and log engine parameters in real-time, create custom dashboards, and record GPS data with your logs.

Is ECU Connect compatible with all cars?

ECU Connect requires an EcuTek Bluetooth Vehicle Interface for full functionality. While it provides basic support for most cars manufactured from 2008 onwards using generic OBD2 CAN communication, specific features and full support are dependent on your car model and an EcuTek tune.

How do I program my car's ECU with ECU Connect?

After plugging in your EcuTek Vehicle Interface and pairing it with your phone via the app, you can create an account, select your tuner, and receive a notification when your tuned file is ready. Then, navigate to 'Program ECU', select the file, and follow the on-screen instructions.
