Scan My Tesla Bill of Materials

• 2020-02-17: Updated to include the (2) recommended passthrough OBDII adapter cables for the Model S

Intro

Thanks to Bjørn Nyland’s YouTube videos (like this one) Scan My Tesla has quickly become one of the most popular diagnostic tools used by Tesla owners. As a track enthusiast who has taken his Model 3 Performance to the race track several times, I have been keeping a close eye on this space for quite some time. Since Tesla does not yet show any detailed metrics in the Model 3 even when “Track Mode” is enabled I sought to fill this void with Scan My Tesla. After a bit of research I settled on a Bill of Materials (BOM) that have allowed me to see what is going on behind the scenes in my Model 3.

Bill of Materials

• Android Phone or Tablet – $TBD
  • Must be capable of running Android 5.0 or newer
  • The lighter the device weighs the better as it will make mounting much easier
• Scan My Tesla Android App – $9.49
• Gooseneck Suction Cup Phone Mount – $11.99
  • I have mounted this to the back of my Model 3’s display and it firmly holds onto my Samsung Galaxy Note 7 without issue.
• CAN to OBD2 Passthrough Adapter
  • Model 3 produced before January 2019 – $29.95
  • Model 3 produced after January 2019 – $29.95
  • Model S produced between 2012 – 2015 and with the last 6 VIN characters <P70000 – $29.95
  • Model S produced after 2015 and with the last 6 VIN characters >=P70000 – $29.95
• OBD Bluetooth Adapter
  • OBDLink MX+ – $99.99
  • OBDLink LX – $49.99
  • NOTE: The real difference between the two aforementioned adapters is that the MX+ supports iOS. This is important as an iOS version of Scan My Tesla is supposedly coming “soon” so if you are an iOS user and want to plan for the future get the MX+.

Closing Thoughts

Once you purchase the appropriate components please refer to Bjorn’s YouTube video that explains how to get everything setup. I have built a custom Scan My Tesla dashboard that has come in handy for both street & track use. This dashboard contains the following metrics:

• 
• Row #1 – Battery Metrics
  • State of Charge (SoC) %
  • Outside Temp Filtered (C or F)
  • Voltage (V)
  • Current (A)
  • Power Consumption (kW)
• Row #2 – Front Motor Metrics
  • Max Discharge Power (kW)
  • Front Motor Power Output (kW)
  • Front Motor Torque Output (Nm or Ft lbs)
  • Front Inverter Temperature (C or F)
  • Front Stator Temperature (C or F)
• Row #3
  • Max Regeneration Power (kW)
  • Rear Motor Power Output (kW)
  • Rear Motor Torque Output (Nm)
  • Rear Inverter Temperature (C or F)
  • Rear Stator Temperature (C or F)
• Row #4 – Miscellaneous
  • Average Cell Temperature (C or F)
  • Battery Flow (lpm or gpm)
  • Battery Inlet Temperature (C or F)
  • Powertrain Flow (lpm or gpm)
  • Powertrain Inlet Temperature (C or F)
