I took the EFI 101 course a few months ago in Seattle, it was a great learning experience. It is more geared towards standalone ecu tuning and how to set it up. It was a two day course, with the first day in the class room doing theory, where you learn how and what each engine sensor operates and the basics on a/f ratios and the effects of timing on an engine. And the second day was tuning a car on the dyno where he show the steps on how to properly and SAFLEY tune a car. It was cool to see him pick up 20+ hp accross the board on a race car that was already fully tuned (by someone else), just by adjusting the timing. There are many good formulas that he gives you, the have/want formula for a/f's works great, and you can actually make a full correct fuel map with math calculations only, and be within a +/- .5 a/f value.
It is also great because you can ask the questions that you have always wondered about and know that you will get the correct answers, from a guy who know his stuff. Ben Strader has wrote many books on EFI and tuning and has worked on many factory race teams like Porsche. The course is based from the book Building & Tuning High Performance Electronic Fuel Injection By Ben Strader.
I highly reccomend it for anyone that is thinking of going with a standalone ecu, as it really gives you an understanding on how everything works from a professional tuner.
