Oil Temp PID '06 LS2
I am using an ELM327 bluetooth OBDII scanner with my android phone running TORQUE. I am able to get reasonable results for Trans Fluid Temp, Coolant Temp, and Oil Pressure. I am not able to get a reasonably close value for Oil Temp using PID 221154. It is varying from 5 to 20 degrees and does not rise at the same rate as the gauge. Does anyone have another PID or have you been successful in getting OIL TEMP?
thanks
thanks

Oil Temp PID '07 LS7
I realize this is an old thread and that you have moved on to a C7, but...
I haven't reviewed the shop manual or wiring schematics to determine whether two oil temperature sensors might be in play, but graphed below are samples of both values recorded during a recent drive. I have a dry sump tank preheater and an oil cooler cover. The ambient air temperature was approximately 80°F. The Torque app is configured to use Custom PID 221154 and shows the OBD equation as A-40.

There isn't one. On cars with an oil temp sensor, the sensor is wired directly to the DIC so it's getting the data that way, if available. It is not available on the CAN bus as it's going directly to the cluster and displaying that way.
On cars without the sensor, it uses the "calculated" or "estimated" oil temp, which is the one available on the CAN bus. Unfortunately, it tends to be less and less accurate the more mod'd your car is.

I am not sure how it works on dry sump setups
