What would it take to make a small 2 stroke controlled by microchip? I've been thinking of using the existing carburetor and taking out everthing except the throttle and gas lines and adding an improvised hotwire mass flow sensor, PIC microchip, and solenoid powered valve. It doesn't have to be as complicated as the system your car might use, just something to keep the air to fuel mixture consistant except for cold starting and maybe idle. What kind of PIC controller should I use? How many I/O lines should I need and how much memory? Suggestions?
