Hey guys, I just picked up a 2002 4 door gtp. I am new to this platform and had a few questions. I would like to get a scanner of some type to keep an eye on things, mainly knock sensor activity. What are my choices for something like this? I had a scanner for my old Lt1 trans am that mounted in the car and tapped into the obd port. Now I've heard of blue tooth scanners but know nothing about them. What are you guys using? My car only has cai and is bone stock otherwise. But I'd like to get something before I start messing with any mods. Thanks
