Dabo here,I have a 95 Z28, 5.7. Ses light is on, I went and bought a Innova 3120d diagnostic tool, it wont work on my car. what I am trying to find out is which one will work on this car? I have spent hours reading on here with a lot of good answers. it appears that the Actron cp9185 or 9145 would be the best bet. But I want to get one that will work straight out of the box.

 

Your car has an OBDI computer, but the diagnostic connector is configured for OBDII. You need a scanner that is capable of OBDI or OBDI and OBDII, and an appropriate cable.
Both will work, but you will need the proper cables from Actron.

 

The best and cheapest way to go is here: Scan9495: Free OBD1 scan app for 94/95 LT1 - CamaroZ28.Com Message Board
Needs only your pc and a $55 cable (or make one for $20). The software is free. Can do trouble codes, real time data, charting, datalogging, actuators, ABS and SIR support.
