Using python to interact with aftermarket engine management controllers. Part 1 will focus on the initial discovery of the controller's serial protocol, communicating with the controller over a serial port, unpacking the byte stream, and using Redis as a mechanism to store and radiate data.
Don't be scared! I'll go over the 'need-to-know' automotive bits quickly so that we can remain focused on python.
This project was the result of my second serious attempt at a project in python. I ended up with a good code base for the evolution of a more complete platform in the future.

Preparing a simulated environment
- Determining your engine's trigger configuration
- Setup ardu-stim (engine oriented signal generator)
- Verify serial connection state with TunerStudio
- Setup MS controller to your engine's specs
- Wiring the things on a breadboard
- Environment setup (redis, pyenv, pip the things)
- ./collect - start data collection in a loop
- read .ini config file to determine packet structure
- open serial connection
- send 'A' command
- collect and unpack(struct) result
- store and publish result to redis
- ./display - display live data
- connect to redis channel
- print published data
- Installation into Vehicle
- Secondary data sources (ardunios, gpio, etc)
