I'll post the name of the program if I can remember it

i am also interested about the program that you mentioned, does it only serve to read trouble codes (those are scan tools right?), or would you also be able to make adjustments in fuel delivery, ignition timing, airflow, etc. using it? is that the reprogramming tool? what's it called?
i also have a copy of haynes repair manual. it's really really really helpful! everything from wiring diagrams, to manual sensor checks and engine specifications are included.
