I am using a $8 ESP-32 micro controller to read the CAN bus, read the Bluetooth data, and drive the LCD display. It is quite the powerhouse!!

Two of the initial design goals was to be affordable and instant start up.

Down the road, I will be looking at using a pi as that will make it easy to drive a larger display. For now, I am focusing on a small (easier to place on the dash) display.

The most difficult and time consuming part of this project has been reverse engineering the CAN bus on multiple Nissan/Infiniti vehicles (like 370, G37, M56, Q50, etc) This is the only way to know if the gauges will work, or what to change in the code so they do work.
