I am looking for a diagnostics program for the OBD1 LT1's. I have an LS1 and have a dianostic program but some of my non computer literate friends with LT1's need help with diagnostic stuff. So what programs r out there and how much do they cost. thanks.

 

I use DataMaster, about $100 from AKM Electronics / Cables.

 

just download Freescan... it works pretty well... takes some getting used to though.

 

where can i get freescan? thanks

what kind of cable do you need for this program? thanks again

 

that acmcable...... well.. pretty much any cable I would guess.

 

i have a cable for my obd2 would that cable work for a obd1? it hooks up to his diagnostic port hopefully all the pins inside are the same. i guess i will just have to give it a shot. thanks

 

nope, won't work.... unless you have a '95... then the plug is the same, but I believe having an OBDI changes the wire scheme. I think I paid like 75 bucks for my cable and it does everything I want it to... including programming it.
