I jsut read all posts about his and I want to say, Good job and great effort! I'll be buying the parts to join in on the development of this great device. I do have a couple of hints though, and it comes from my EE education and background. the inputs from the VSS and injectors needs to be built up. opto-isolators would be a good idea as they will protect the processor and they can take way more punishment plus will help to shape the signal to be more of a square wave.
