Turncoat

I'm trying to figure out how to interpret the below Torque Lite display. What is the difference between "O2 Sensor" and "O2 Sensor Heater" in relation to the actual O2 sensor setup on the car? Is one referring to fronts while other refers to rears? How would one interpret this output for a car with LT headers that only runs off one set of sensors? I know you can graph voltages from individual sensors, but if the car is only using the fronts in the tune, what's it checking for readiness?

1st of all LT headers are illegal in most states If you live in a state where they are legal your state may have other smog rules that will keep your car from passing smog beyond the LT's
LT's require you to delete your rear 02 sensor readings Remember that the rear 02's do not have anything to do with how your engine runs--they are there ONLY to report the condition of your cats But LT's often skew these readings and will create codes AND not allow ALL your readiness monitors to set to "ready"
Your easiesr fix is to get a maiil order tune and have them Permanently DELETE all your rear 02 reporting You could drive your car to Alaska and those monitors will never ever set !!!
ALSO If you are getting FRONT 02 codes again this is common with LT's As with LT's the front 02 bungs are moved rearward from 2-3 ft consequently they will never ever read correctly and throw codes PLUS beacuse they are so far back they will not heat up correctly and give false AFR readings so you engine will run pig rich and be down on power
Again a tuner can make adjustments to help the front 02's read better and again permanently delete all the front codes just to be sure that all the 02's front and rear will have the monitors read READY Forever---
