I decided to open source my stand alone VP44 electronics project. I started a github repository.
It's far from a bolt on replacement. It's just a prototype but it has been running reliably for a couple of
years now. Unfortunately, it's not a project for beginners and requires good soldering experience
and there is one surface mount part on the board. The circuits have some high energy parts and requires some testing
before operating. The software is not simple and has time critical routines. An in depth understanding of the MCU
internal peripherals (timers, PWM) is also required. Any mistakes in assembly or coding can cause permanent damage to the fuel
solenoid or speed sensor.
My project explores the electrical operation of the mysterious VP44. I included some diagrams and tutorial.
The mechanical operation is described on various websites so I skipped it. It may help to review some of those sites.
