Highway driving in subfreezing temps with no block off plate on the cooler, my oil temp readout stays a consistent 160. Valve on the thermostatic plate fully opens at 180.

If our concern is ECU pulling timing due to high oil temps, then yes, whatever the sensor says is what the programming responds to. Just remember that oil temps in the block are 20 degrees higher than the sensor readout.
