Bob's article is a very good primer for EFI concepts. The problems with it are that most of the stuff he used is now at least 20 years old, and is not tailored specifically for your engine. Most of the guys with slants are using Mega Squirt, which is a share ware concept with such a large following that there are now companies preassembling the ECU's and selling them at very reasonable prices. They also sell kits which you can assemble yourself. The real strength of MS is that there is such exhaustive support. Go to
www.Megamanual.com and read,read,read. There is a very useful tech forum for Mega Squirt which you join just like this forum. Sometimes that can seem a little negative in nature since the posts are mostly from guys having problems. You don;t get to read the success stories as often as the challenges(problems).
I have gone with Accel GenVII, which is a good system, but the documentation, tech help, and instructions are terrible. I don't recommend Accel for this reason, even though it works well.
There are many, many other systems out there, and a search of the web will find them. The most critical difference in my opinion is what kind of tech support they offer. Mega Squirt is cheap, and works well enough for most needs. This means that you will be able to get your car running well before you exhaust the features offered. Go for MSII. This offeres timing control, and makes the system pretty complete in the control you can design into the configuration of the system just for your car. The base system, or MS does not offer timing control, but keeps your old mechanical timing control with centrifigal and vacuum advances. This will work, but has serious limitations.
The more control you build in, the more tuning you will have to do,and the possibility exists that you may never get it just right. Sometimes simpler is better. I would do this again, in spite of the fact that it has taken a long time to learn. Good luck in your research.
