Activate the oxygen sensor on oldsmobile cutlass ciera sl0 1990 3.1L
 

Hello
Thanks to all the friends for the good stuff
I want to say something and I need your helps
please guide me
my vehicle is oldsmobile
Engine model: cutlass ciera sl0 3.1L 1990
KM sensor: 15 gears
Motor platform : AB
EGR Status: not
ECU Model: ATBF
Memory code: 1227730
This engine model was presented to the Middle East
The oxygen sensor is inactive (the oxygen sensor's location is embedded), because that time was gasoline, had a lead
And activated at ECU when the engine temperature reaches 360 degrees, so it's disabled.
That's why the fuel consumption of the car is very high
Now, can you EDIT the ECU memory stick with OBD device and define the engine temperature for the oxygen sensor to 80 degrees and close the loop and Update other settings? (Here, OBD device for older GM is not binary.)
Can you do this?
I add, this model Engine is similar to the Oldsmobile Supreme car.
