Reply to "Fuel Injection and Electronic Ignition for VW engines - Speeduino Style"

All of the computing power for the Speedy comes from a standard Arduino CPU board. The Speeduino units plug directly into the Arduino board. Use the Arduino 2560 board to avoid heartache:

I highly recommend using a Hall Effect crankshaft sensor rather than a Variable Reluctance (VR) sensor because of the vastly reduced susceptibility to ignition interference. If not, you'll need a small daughter board called a VR signal conditioner:
