Basics
- S3 EFI
- An Electronic Fuel Injection System Developed by Robot Cantina (YouTube Channel) / Jimbo that is based off of the Bosch CIS System
- It is somewhat in-between a “dumb” Carburetor system, and a modern “smart” system like a Speeduino with tons of sensors / Dual Injection etc
- Low Complexity/Points of Failure, but just smart enough to work reliably is the design goal
