Here you will find lists of frequently asked support questions (FAQs) about common issues with ECU Connect. Feel free to ask us anything not answered here by mailing us on firstname.lastname@example.org, but please read the FAQ first.
Will ECU Connect work with my smartphone?
ECU Connect currently works on iPhone and iPad (iOS 10.2 required) and Android phones and tablets (OS version 5 and above).
Will ECU Connect work with my Bluetooth interface?
ECU Connect requires an EcuTek Bluetooth Vehicle Interface, also referred to as EVI-BT. This hardware allows you to get the best possible performance, in particular when data-logging. ECU Connect will NOT work with any other interface, including ELMxxx-compatible dongles.
Will ECU Connect work with my car?
Please see ECU Connect Webpage for supported cars and features. Some features are only available when RaceROM is installed and it has App support. If your car has already been tuned, please check with your tuner if your car has a recent version of RaceROM that includes App support.
Can I leave the EcuTek Bluetooth Vehicle Interface plugged into the OBD socket all the time?
Yes. The hardware is designed to remain plugged in all the time. The power consumption is very low so you don’t have to worry about draining the battery, even if you don’t drive the car for a few weeks. If you plan not to use the car for more than a month, we recommend to disconnect the battery.
Can I use more than one device with my EcuTek Bluetooth Vehicle Interface?
Yes. You can use it with any number of phones and tablets. Only one device at the time can be connected.
Can I use my EcuTek Bluetooth Vehicle Interface with more than one car?
Yes. You can use the Vehicle Interface an the ECU Connect app with any number of cars.
Why does my EcuTek Bluetooth Vehicle Interface not reconnect automatically to my iPhone/iPad?
Please be aware that the EcuTek Bluetooth Vehicle Interface will only reconnect automatically to the last device it was used with. For instance, if you normally use it with your iPhone and one day you pair it to your iPad, from that moment it will try to reconnect to you iPad. If you wish to use it with you iPhone again, you need to connect manually from the iPhone by going to Settings → Bluetooth and selecting the EVI-xxx item on the list. Also see the next point.
Why can’t I connect to my EcuTek Bluetooth Vehicle Interface?
The EcuTek Bluetooth Vehicle Interface only supports one connection at the time. If it’s connected to a device already (status LED is BLUE) then you won’t be able to connect from another device. Please disconnect it from the existing device (for example by disabling the Bluetooth) and try again.
If you've just updated the firmware you might also need to unpair/forget the device and pair to it again.
On iOS 11.2.5 some devices are known to have connection issues. If you tap the "My car" button and the app shortly goes back to main screen showing "No vehicle interface detected" then you're affected by this issue. In this condition the EVI-BT will still be connected over Bluetooth but the App won't be able to "see" it.
This is a bug in iOS which has been addressed in iOS 11.2.6. Please make sure you're running the latest version by going to Settings > General > Software Update.
Why is my car not detected?
Please visit ECU Connect Webpage and make sure that your car is supported. If it is, the ECU could have a very recent or unknown calibration. It should be soon supported via an update. Contact you tuner to make sure this can be added.
Why is my car detected but I only get basic features?
Advanced features require a version of RaceROM to be installed that includes App support. Go to Info → ECM and check that RaceROM is “Installed” and App support is “Yes”. If this is not the case, please get in touch with your tuner to get an updated tune that includes the latest RaceROM. Otherwise, the feature you’re looking for is just not available for your car.
Can I use my EcuTek Vehicle Interface as a generic OBD code reader?
Generic OBD2 support has been added and provides OBD PID logging, along with read and clear DTCs for all compliant vehicles around the world. There are many different OBD2 standards and protocols and we are unable to guarantee support for all vehicles, but many will work. Give it a try and see!
What does the LED colour indicate?
The status LED will indicate the Vehicle Interface status in different operating conditions. Please read the EcuTek Vehicle Interface LED Colours for the summary of the possible colours.
How do I connect and disconnect the EcuTek Vehicle Interface?
The Bluetooth version of the EcuTek Vehicle Interface (EVI-BT for short) allows to establish a wireless connection to a mobile device, such as a smartphone or tablet. The connection process is different depending on the device type. Please visit the following link (the Bluetooth connection explained) to see the details that are important to understand while troubleshooting connectivity issues.
Can I flash my car with ECU Connect?
No, you cannot flash a car using ECU Connect. ProECU is the only software from EcuTek that can program a vehicle currently.
Can I flash my car using the EVI-BT?
The Bluetooth EcuTek Vehicle Interface (EVI-BT) can be used for programming but care should be taken due to the fragility of the mini USB port. It must be used in conjunction with ProECU as ECU Connect cannot flash a vehicle.
When trying to rotate my device to landscape to view the Dashboard an error message is displayed?
Dashboards can only display in their assigned orientation because the change in size requires reorganisation of the widgets. Please create a new Dashboard to allow your device to display info in landscape. How to Create a Dashboard
