First time using the application so bare with me ...
I have downloaded the stock Calibration and saved it on my Laptop.
I wish to turn off the down stream oxygen sensors on my truck do to the CEL being on for headers and high flow cats I installed last week.
Is there a switch already baked in to toggle that on and off ?
Or do I need to find the specific DTC turn the light off for it ?
This will put the truck back in closed loop correct ?
Thanks in advance
