Technical Articles & Information

Most of these articles are from people other than myself who have either more experience or knowledge about the subject than I do. If they are listed here, then I either recommend them or have even used them myself. I have also included comments about each.
Feel free to read, use, and give any feedback!

1) Programming EPROMS for GM TPI Systems ThirdGen.org

Highly recommended article. Includes a breakdown of what you need to get started.

3) ALDL Interface Schematics Andrew Mattei / Craig Moates

Use the AKM schematic or buy one from Andrew Mattei. I believe this works with all TPI systems (TBI also?)
4) TPI and Engine Basics ChevyThunder.com
http://www.chevythunder.com/
A lot of good tips for troubleshooting and modifying TPI engines.
5) RS232 Communications - Tutorial http://www.arcelect.com/rs232.htm This tutorial explains how RS232 communication works. Might be handy in trouble shooting the ALDL interface.
6) 10 Segment Air/Fuel Ratio Meter Schematics Jari Porhio's Project from DYI_EFI.Org
http://www.students.tut.fi/~eppu/dev/EGO-bar.html
Very, very helpful in tuning your fuel injected system. Just needs a signal from your O2 sensor (I prefer heated), sensor ground, and 12volt source (or 9V battery if you like,)
7) DIY_EFI and GM_ECM Websites http://www.diy-efi.org/ Plenty of usefull information, articles, and projects for the fuel injection "Do-it-yourselfer".
8) Choosing a TPI System Street and Performance
http://www.hotrodlane.cc/Streetstories/choosetpi1.htm
Want to know the differences in TPI systems by make and model? Check this site out. Need more answers about converting to TPI? Give these guys a call. If you can think it they've probably done it.
