I considered such a project one time, there was an article in an past issue of CIrcuit Cellar about a fellow that had made an injection system for a college project vehicle, going for extreme fuel efficiency. Interesitng article. Anyway, the basic engineering is in there. The Bosch book on fuel injection, the exact title escapes me right now, has a lot of things in it about the solenoid valves and injectors and injection generally. The way I was going to proceed is find out what the flow rates of the injectors were for various RPMs also checking the pusle widths to the injectors. There's a finite period for opening and closing, on the order of 1-2 milliseconds as I remember, that you'd have to take into account when designing the controller. I'd like to get a closed loop system, one including an oxygen sensor(no high-test leaded anymore) and maybe some iginition control. Would be quite a project. One of the Southern CA bug parts places has such a beast, think it runs in the low kilobuck range. Kind of a toss up whether it would be worth it designing it or just go buy one.. Good luck if you go that route. If I had some more experience(and unlimited time and funds) with other types of Bosch units I'd try adapting one of the later units, maybe a K or KE Jetronic.
