EFI and Ignition: 4-Coil DIY Engine Control Module
Channel: Dielectric Videos
Date: 2022-07-21

After many months of test driving, the latest DIY engine control board has arrived! This PCB incorporates the same 2-sensor fuel injection system as my previously featured board, and now includes support for an optically-triggered high-energy ignition system! 

The mainboard and distributor board are designed around the VW air-cooled engine platform, and the optical interrupter is specifically designed to work with the Bosch 009 distributor and rotor. If you'd prefer to keep your existing ignition system or have an engine with more or fewer than 4 cylinders, check out my earlier video on DIY engine control: https://www.youtube.com/watch?v=5qQvote2_eA

If you would like to see how to harden your Arduinos against EMI sources such as those produced by a spark ignition system, I have a video for that as well: https://www.youtube.com/watch?v=PKhBNk9ZuHc

If you'd like to see a complete, uncut assembly of this PCB with some soldering tips, I have a video of the process here: https://www.youtube.com/watch?v=miBk3u-yEhw

And if you'd like to see the original video where this whole project started, check this one out: https://www.youtube.com/watch?v=kj24iWmM_PU
