    we need a lot more info Dave. Both vehicles came with a lot of different engines and different ecus (more so the S10 than the hhr, but there are still multiple for the hhr)

    THE S10 IS A V6 2003 ECOTEC
    HHR SS 2.0 TURBO 2009

    SO MAYBE ITS AN ECU issue and not the software. just funny how the older s10 shows the controls.
    thought I was doing something wrong.

    thanks for helping

    There are not many controls for the HHR you have. I'm not familiar with the s10, so maybe that is the problem you are thinking you see.

    Different ECU builds, not familiar with the S10, but the HHR shares the ECU of a LNF which is Bosch direct injection torque based control system and is vastly different than what GM was using in the early 00s.
