what do I need to tune?

I know I need a laptop and software but do I need to buy an additional
cable besides what will come with the software. Thanks for any help.

Going to need a wideband of your choice. LC-1, LM-1, AFX. I went with the LC-1 because I got a good deal on it. Im kinda wishing I didnt go with the LC-1 because of the grounding be so picky and the sensor over heating with the Bosch sensors.
