hey fellas! i bought a used v1.2 from a guy and i dont even know where to begin. im not even sure that i have my car on there. i plugged everything in and had the key in the on position and was trying to look around but i have no clue what to do? im trying to turn of the egr,air and rear o2's and haven't found where i can do all that. is there anywhere that i can look to make sure that my car is in the system? i probably shouldn't of even bought this but i thought"well got to learn sometime" but i really think i should of trusted my gut on this one and not bought it and let the professional's do it. thanks for any and all info ahead of time jim.
