Toyota Technical Articles

These are training materials used by Toyota. I’ve collected them from various places on internet. They are a very good introduction to EFI engines in general. Recommended reading for anyone planning to install an EFI engine, or just wanting to know more about how they work. To view them, you will need ‘Adobe Acrobat Reader’:http://www.adobe.com/prodindex/acrobat/readstep.html.
