so ive had my rx65 for about three weeks now, and Love it! however i also have two cobras..i know i know..boo!!!but they were before i found this great site. anyways. i just went out to the garage and turned the rx65 on in my truck, then i turned one cobra after the other on in my gf's eclipse. however expecting my rx65 to detect the leakage it didnt..so my question is, is my rx65 not detecting right, or are my cobras not leaking much or none at all..
