[QB93Z]

I am glad you started this thread. I have wanted to learn more about the Tech1.

The cartridge that I use the most is:

GM/Ford/Chrysler Power Train (GM 81-94) 02001718

I also have:
GM 88-91 Body Systems TK 03040
GM 88-92 Brake ver2.0 TK 03030C
OBD II Interface Cartridge 02002178
Global OBD II w/Toolpack OBD II Interface Cartridge 02002826
Chevrolet EEPROM Service TK 06030 10912

I also have two adapters to connect to the different year connections:

GM 12/14 Pin DLC Adapter 02001384
GM 16/12 Pin Non-OBDII DLC Adapter 02001575


Unfortunately, I have never found a listing of the available cartridges. I have never found a list of the tests or functions that a specific cartridge can do. If anyone knows where to get this kind of information, please post up.

I use my Tech 1A often. I find it a valuable tool for a backyard mechanic.
