+Overview
+--------
+
+Speeduino is able to support Canbus in two ways.
+
+1. Use a Mega2560 MCU with a coprocessor board
+2. Use a Teensy or STM32 (with internal can module) MCU.
+
+##### About the CanBus Interface
+The Canbus Interface offers ,
+
+  1. OBD2 formatted data of current realtime data .
+  2. Broadcast selected current realtime data and function status .(coming soon)
+  3. Read in Analog and Digital data values from other devices on the BUS including those from OEM devices/ECU.(coming soon)
+
+Settings
+--------
+
+### Enable CanBus interface
+
+To enable use of the Canbus interface it must be enabled in TunerStudio.
+
+
+
+
+## OBD2 Data Support
+
+When used with an MCU that has an Internal canbus interface Speeduino firmware is able to output data using the OBD2 std 
+
+Speeduino does not offer “readiness monitoring” or emission testing support and should not be used for such.
+
+### OBD Port Interface Configuration 
+
+The Interface supports 11bit addressing @500kbps data rate.
+The port will respond to the STD OBD2 protocol .
+Any code reader /app /software following OBD2 standard protocol is able to access the data described below.
+The Teensy3.5 uses pins xxx for connection to the can transceiver.
+The STM32 uses pins xxx for connection to the can transceiver.
+
+### OBD Port Interface Support Options
+
+The OBD2 port Inteface offers support for ,
+
+   1. To output the current realtime data ([see supported PID list](CanBus_Support2#PID_supported "wikilink")) . 
+   2. Output the Analog/Digital data values from the 16 Aux inputs ([see here for info on aux data input configuration](/en/configuration/Auxillary_IO_Configuration))
+   3. Activate External Outputs(coming soon!)
+
+### PID supported
+
+The following PIDs are supports by by the OBD port
