srenner / carfuino

[Arduino] Automotive performance computer with Megasquirt integration

carfuino

CAR + perFormance + ardUINO = carfuino. Pronounced "car-fween-oh." Or however you want. I don't care. Vehicle performance monitor.

Overview

• Provides a display of various performance metrics:
  • Base view with trip info
  • Realtime g-force
  • 0-60 acceleration time
  • 60-0 braking distance in feet
  • 0-100-0 acceleration & braking time
  • 1/4 mile time and speed
• Designed for a 1980s-1990s aesthetic

Hardware details

• SparkFun AST-CAN485 Dev Board
• ADXL335 3-axis accelerometer
• 16x2 character LCD
• RGB LED to show system status
• Button to switch between modes and view records

Extra Arduino dependencies

• TBD

Vehicle dependencies

• Speedometer input to carfuino via CAN bus
• VSS pulse count input to carfuino via CAN bus (used to measure distance traveled)
