    AEM 30-0334 not connecting to HP Tuners MPVI2

    I just installed this wideband, everything works but once I plug in the pass through OBD2 and then try to plug my HP Tuners to the pass through, it cannot connect to vehicle. Then I remove the AEM passthrough and HP tuners is able to connect. This is a 2008 C6 Corvette and help is greatly appreciated.

    I wonder if the AEM passthrough has an issue of some sort.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    I am thinking that may be the problem also. I have emailed AEM and I am awaiting a response. Hopefully something simple so we can get this car tuned and to the track.

    Problem found. While checking for continuity, the OBD2 port had a pin that looked wider than the rest. I de-pinned it, closed it back up with some LIGHT pressure on some needle pliers and it all works again. Not sure why it would only connect to HP Tuner and not with the AEM pass through, maybe too much resistance? Regardless it works now.
