help - which module for Tech1?
 

Hello!

I have a tech1 that I bought some while back to use on my 1991 Grand Am;
A local is interested in borrowing this, or my 3rd party scanner which has live data available;

Can anyone tell me, for a 1992 Firebird Formula, what module is required to be plugged into the Tech1?

Tech 1 used many different cartridges and each had a name tag on it which told what it covered. Eventually nearly all the individual cartridges were combined into one called “Mass Storage Cartridge”. Do you have one named that? If not look for a cartridge that reads “GM 87-91 ECM. Only covers engines and not ABS, SIR and other systems.

SWEET!!

I have both of those!!

Thank you very much for helping me out!!
