For anyone who has never heard of the MegaSquirt it's an Open Source ECM technoligy. You can actully but the ECM in pieses and build your own. I have read the manual and learned a lot about EFI systems in general. The MegaSquirt has differant versions and they have parimeters to run just about any sensor. Very interesting for the GearHead!
One of the best suppliers I have found for MegaSquirt ECM it kits or already built is DIY Auto Tune. They are also a great place for many DIY fuel injection needs. I got my JimStim from them and they also carry all small parts to service what they sell.
