How to activate the oxygen sensor on ecu for oldsmobile cutlass ciera sl0 1990 3.1L?

Asked by GuruZX5LF Oct 24, 2017 at 06:10 PM about the 1990 Oldsmobile Cutlass Ciera SL Sedan FWD

Question type: Car Customization

Hello
Thanks to all the friends for the good stuff
I want to say something and I need your help
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?
(Here, OBD device for older GM is not binary.)
Can you do this?
I add, this model is similar to the Oldsmobile Supreme car.

I may not have understood your post and am assuming you live in the States /// how dis you get tags without an emission test? You are aware that the Catalytic convertor is dead so and O2 sensor is useless (If it even has a cat) .. Leaded gas will quickly destroy a catalytic convertor by lining over the platinum with lead .. after market cats are not that expensive and once it's working you can program the ECU. BTW your poor mileage may be from a restricted cat (if it has one)
