    Thanks.
    The ECU doesn't "know" anything has changed. It only sees a voltage input from the TGVs. So, you just have to log TGV voltage and you'll get the voltage of whatever you have coming from whatever sensor you choose.

    Might that cause the ECU to "act" on those inputs. Since the readings would not be what the ECU expects.

    Other than the TGV, what other inputs could be re-purposed as I would like to log 4-5 new sensors that don't currently exist.
