About this app

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!

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.

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).

Ratings and reviews

Weird glitch when flashing a revision it'll hang up at 100% until I turn car off then it'll say "turn car off". That always gives me anxiety, but so far every revision seems to load well. The ui could use some more options. You have to adjust phone display settings to make gauges go smaller. The decimal points are ridiculous like for 2nd "gear" it's like 2.00000000 🤣. But overall I still like it. I hope they add to it and refine it. It has lots of potential

I have been using and I have to keep an older version of the app, the new version/ every update makes the app not able to connect to the Bluetooth. I basically have to test every update and see if it works for me, if not, have to go back to the older version(4.16.7.0). Other than the above, it works great.

Latest update (version 6.0.0) broke the landscape view. It will not stay its position after you move it around. I have to go back to the previous version.
