Just droped a new motor in it and rebulit the tranny. Just starting to get it runnin and want to add some mods! How do i tell what kind of comp. i got? Its a 94 Z with an 98 model lt1 buick motor! I changed the heads though. Which computer is better or is anyone better than the other?

 

Cars built in 1996 and later have OBD2.

 

95's have the obd2 connection but are obd1.
