I did. I got a lot out of it. It's definetly worth the price. Since I took the course I was able to fix up a few rough tunes and also get a car running on Megasquirt which is a pretty decent challenge. The walkthrough of writing a basemap and calculating required fuel values that efi101 teaches is invaluable if you are doing an 'off the beaten path' project like a Megasquirted turbo E30

Before you take the course I would highly reccomend reading two books. One is written by the course instructor and founder of EFI University, Ben Strader.




This book covers the basics as well as outlines different systems including the one that you will probably watch the on-dyno demonstration on (Autronic or AEM).

The second book gets much more indepth and gives several complete walkthroughs on project cars - complete EFI system installs. Actually you might not even need the first book if you soak this one up first:



Only thing you need to bring is a well-rested mind, a small notebook, and pen. Notebook is optional since you can just scribble in your EFI coursebook but I wrote down some additional stuff. There is a ton of material covered in the first day - think hard and save your questions until the end of each segment, in my class there were a lot of people asking questions that were answered in the next 5 minutes.
