## What is ECU Connect?

IMPORTANT
This app requires an EcuTek Bluetooth Vehicle Interface to connect to your car's ECU. These are available from EcuTek Tuners. Find your nearest one at www.ecutek.com/dealers. If you don't have an interface, run the demo mode within the app to see ECU Connect in action.

ECU Connect is the free companion app to the new pocket-size Bluetooth Vehicle Interface produced by specialist tuning firm EcuTek Technologies.

Once you have purchased your EcuTek Vehicle Interface, plug it into your car's OBD vehicle diagnostic socket, pair it with your phone in the app and you will open up a whole new world of enjoyment with your car.


With ECU Connect, you can receive and program in a tuned file from one of our EcuTek Master Tuners just with your phone. No laptop, no wires, no fuss. Just create an account in the app, select the tuner you want to work with, and you are ready to receive the tuned file. Discuss with your tuner what you want to achieve from the tune and once the file has been created, you will receive a notification that the file is ready. Go to Program ECU, select the file and follow the on-screen instructions. It's as easy as that. All that's left is for you to enjoy the car!
For more details on programming your car’s ECU with ECU Connect go to www.ecutek.com/phone-flash

Your EcuTek Tuner can also set up some unique RaceROM features which allows you to control and adjust some aspects of the tune with your phone: Launch RPM; Traction Control settings; boost and torque levels; switch between different set ups such as track mode, economy mode, fast road and flexfuel on the fly. These are just some of the example set ups. Speak to your EcuTek Master Tuner and discuss with them what you'd like. There are lots of options to choose from.

For a list of supported models together with their ECU Connect Features go to www.ecutek.com/ecu-connect

Whether your car is tuned on EcuTek or not, with ECU Connect you can instantly see how your engine is performing as you drive it (even if the car is not officially supported, ECU Connect provides basic support for most cars using generic OBD2 CAN communication protocol available on nearly all vehicles manufactured from 2008 onwards). You can view and log any parameter the ECU records and even create unlimited personalised dashboards if you want to monitor specific groups of parameters. Save and send these logs direct from the app to your tuner. You can also record GPS coordinates in the log files, so you can see what was happening at any given point on your logging run (very useful on track days).

## Key features

- Program tuned ECU files wirelessly
- Real-time engine performance monitoring
- Customizable parameter dashboards
- Log engine data with GPS coordinates
- Adjust RaceROM features on the fly

### 4/5 — Great app but needs to work with Apple Carplay

*2026-03-31*

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.

### 4/5 — Apple carplay

*2026-03-29*

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!

### 1/5 — Don’t change the background picture of your dashboard

*2026-02-20*

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

### 3/5 — Super finicky

*2026-01-22, version 7.4.0*

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.

### 3/5 — One Flaw

*2025-11-20*

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.

### 5/5 — Gr86 Tuned

*2025-11-12, version 7.1.6*

My GR86 got tuned by Teqsport which is a great company. Check it out 😆

### 5/5 — Please develop a CarPlay widget.

*2025-11-06, version 7.1.3*

Could you create a CarPlay widget, please?

### 4/5 — Add CarPlay

*2025-09-17, version 6.26.0*

Add a CarPlay feature to put your dashboard on your CarPlay app! Would be so cool and helpful!

### 1/5 — No longer working for iOS

*2025-08-14, version 6.24.4*

Latest firmware update is no longer allowing the app to read the car interface when using iOS app. Please investigate.

### 5/5 — This is the best

*2025-08-11, version 6.24.4*

Thank you, EcuTek, for this legendary technology and the ability to tune, upgrade, and receive programming from the comfort of home. I hope you continue to develop and add even more amazing features. I truly appreciate your efforts.
