    Onstar "Tattletale"???

    I recently ran across a first, I tuned a buddy's truck, after he saw the MPG gain and felt the power increase, he wanted the same done to his wife's 05 Tahoe. Upon further discussion with the wife, we discovered that she pays for the monthly diagnostic E-mail report from Onstar.
    I didn't tune the Tahoe, seeing how they live 5 states away I didn't want to create any confusion between the PCM and Onstar.
    What kind of report would she get if I were to SDRTT tune via LM1?

    My thinking was initially she would prob. get a crazy report listing such things as COT, MAF and general PCM communication. But after driven for a bit w/ no check engine lights on, it would prob. be OK?

    Or would the authority's track me down, while I'm trying to dial in the MAF.........

    You could always pull the Onstar related fuses but I haven't run into Onstar issues like that.

    My ODBII port is powered through the On* fuse. Can't pull it during tuning.

    Iwas thinking the same, Cig lighter usually is the culprit of Dead OBDII due to blown fuse.

    Onstar doesn't track that info in real time, they just pull it once a month right before they email it to you.
    I get the reports by email, but nothing out of the ordinary.
