DIUS ULA - Universal lambda adapter

ULA - Universal Lambda Adapter (hereinafter - the device) is designed to control the quality of combustion of the fuel mixture using a BOSCH LSU 4.9 lambda sensor. Currently the device supports two modes of operation:
1. Lambda to CAN - designed to transfer the values ​​and operating parameters of the lambda over the CAN bus
2. Lambda to WiFi BRP - transmission of lambda readings and engine operation, temperature, etc. via WiFi to any device (phone, tablet, computer) with saving the log of the transport in the device for further downloading and processing data.

DEVICE SETUP

To start using the device, you must perform the following steps:
1. Install the lambda sensor in the exhaust manifold of the engine or install an adapter for the lambda between the manifold and the exhaust pipe, depending on the type of vehicle.
2. Connect the lambda connector and vehicle OBD (diagnostic connector) to the device.
3. Activate the vehicle to power on the OBD, and then on the phone (tablet, computer) in the WiFi network settings you need to discover a new ULA network. Connect to it, the default password is 12345678.
4. In the phone's browser, enter the link to the device address 192.168.5.1, after which you will see the adapter settings:

5. You will need to enter the data of your Internet access point in order to connect to the server and download the firmware you have chosen to purchase and your REAL Email address so that you receive additional information about updates for your device.

If you entered everything correctly, then after clicking the "Connect to server" button, you will see that the device is connected to the Internet and ready to download the firmware to choose from (depending on the equipment you purchased), in my case you can choose from two options which are valid regardless of firmware, the process for all firmware is the same.

6. For example, I choose the first firmware, followed by a warning that the device can not be de-energized when updating the firmware and the process of loading the device

7. Then we see the process of downloading the firmware.

8. Download completed successfully

After the firmware download finishes, the device will reboot automatically, you will lose connection with the device for a while, so I recommend on your phone, tablet to set up automatic connection to WiFi ULA, in order not to reconnect to the device after reboot. We will see the updated window of the ready-to-work device:

9. In the WI-FI AP tab, you can change the network name and password of the access point to the device or leave the default if you are not using several devices at the same time.

10. LIf something went wrong: the power of the device turned off when updating the firmware, the Internet disappeared during the download of new firmware, you changed and forgot the password for the device’s access point, etc. and the device stops working, you can return the device to Factory mode. To do this, the device must be disconnected from the OBD connector, place a powerful magnet near the inscription http://192.168.5.1 on the front side of the Sutroist. After that, connect the connector and turn on the ignition key. Do not remove the magnet within 5 seconds, the device will return to the Factory firmware. All settings will also be reset, such as your Email and the settings of your Internet access point. Also, the settings of the built-in access point will return to the default values (ssid: ULA pass: 12345678).
