So Ive been having problems with my car for the past month, and Ive finally narrowed it down to my interface box atleast I think so anyway,
when I run either of my 2 p28s with j1 cut I throw no codes, when I reconnect j1 in either one of them and run a chip I still throw no codes, but as soon as I reconnect my s200 interface box I throw a code (code six ect sensor which I replaced with a new one) and the box blinks, does the interface box have some type of memory on it that has to be reset by a dealer? Thats the only thing that I can think of that would cause this.
