HOUR/DATE:
Press the designated button to display the current time. Press again to switch to the date view. Adjust the time and date by pressing the appropriate buttons.

GPS SPEED:
Press to view the current GPS speed.d Press to display the current GPS speed. The overspeed alarm can be activated using . Press once to set the limit speed using the numerical buttons, and press again to activate the alarm (‘ON’ will be displayed). Repeat the operation to deactivate the alarm. In case of an overspeed, ‘LIMIT’ will blink on the screen until you slow down. You can ignore the alarm by pressing .0-60 and 1/4 MILE TIMER: 

Press to display the 0-62 timer. ‘READY’ will be displayed once at full stop. The 0-62 timer will start right when an acceleration is detected and will stop once you reach 62mph (100km/h). Press again to display the 1/4 mile timer, which operates the same.

LAP TIMER: 

Press to display the lap timer. Press to set the starting line to your current position. A running timer will then get displayed, until you cross the starting line, which will display the elapsed lap time. Your fastest lap and delay with it will also get displayed on the following laps.
Press to end the lap timing. Your fastest lap and total number of laps will be displayed.

MPG, RANGE, REMAINING FUEL, AND TRIP ODOMETER: 

Successively press to display your hourly fuel consumption, mileage, range, remaining fuel (if compatible), and trip odometer. Those values are computed from variables (injector size, engine type, etc) that need to be set up. Please refer to page 12. The tripp odometer can be/reset using

TIMER: 

Press to display the stopwatch. It can be started and stopped with. Once stopped, press to reset. The stopwatch features a split function allowing for the timing of a second interval, which can be activated by
Pressing when the stopwatch is running

GAUGES: 

Successively press to display the oil pressure, oil temperature (if equipped), and voltage. An overheat alarm can be activated by pressing , which will display an alert message if your temperature exceeds a pre-selected value, which can be ignored by pressing

 INFORMATION. Successively press to display outdoor temperature (if equipped), accelerometer, current heading, and altimeter.

SET/RESET:
Press and hold to power on/off the onboard computer. The OBC will automatically power off if left inactive for an extended period

Digits

As mentioned earlier, some functions may take numerical values. These values can be entered using the dig buttons. Example: Pre ss + + + to enter 112.  You can also enter negative numbers by pressing and holding the corresponding buttons.

Settings

Settings can be accessed by simultaneously pressing and . Each setting is associated with a corresponding number, as described in the following table:

Wifi UPDATES. 

• New software updates will frequently be released to fix potential bugs and add features.
• To install them, please navigate to the setting “SET 3”.
• For one minute, the OBC will try to connect to a known Wi-Fi hotspot to download the latest version of the software.
• If no known WiFi hotspot is available, or if none has ever been registered, the device will become an access point, waiting for you to connect to it.
• Using either your phone or your computer, please look up the “E30 OBC” WiFI hotspot.
• Once connected to it, you will get redirected to obc-80s.engineering.
• There, please type in an available WiFi hotspot SSID and password.
• Once registered, the OBC will use those WiFi credentials to attempt to connect to the internet, where it will download the latest software. (from https://github.com/80sEngineering/OBC)
