I have a new proto type with custom circuit boards so I don't have to worry about a big mess of wires and components moving around and causing problems. I can move on to working out more of the code. My tune tables need some work and I need to build an ECU to operate my guage cluster and OBD2 port. Got my transmission signal working pretty good. I need to make a TPS calibration routine. Here's a new video of it running. -
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. https://github.com/Greatwrk/VP44-EXPLORER
