I'm a newbie on here researching tuning/monitor tools. One thing I was wondering is are you required to buy a Flashscan to perform these tasks or do they have just a OBDII/USB Cable that lets you hookup your PC to your ECM and use software DL'd off here (or purchased off the EFILive website) to tune/scan your engine? Any help would be appreciated since I am a LITERAL babe in the woods on this computer tuning stuff.
