I'm getting ready to open the box of DEMONS called tuning, and frankly don't have a clue where to start.
I think I want to go the route of a PCMFORLESS tune by mail, but I need advice as to what I need such as cables,scanners, programmes etc. In fact I'm not even 100% sure where to connect a cable and laptop to, but I think it is under the glove box.The car is a '94 Z and I only have a laptop at this point.
