hello all i,ve got a 85 iroc tpi i am a newbie when it comes to lookin at a scaner and seeing the blm and the ve stuff and the o2 voltage and cross counts. i would like to know how diffrent readings interact with each other.
i would like to know where the ideal setings should be if one goes up or down whats does it mean and what should i look at or do to fix it. i dont have a problem with the car right now not that i know of. but i am going to do some mods like intake porting and a cylinder head swap. i would like to know some helpful info so i can translate my ecm lingo.i have speant a bit of money on my motor and i would like to protect my investment.

thanks all
