Waht do I do with extra sensors Looking for opinions. I replaced my factory headers and installed a off road y pipe. The facotry set up has 4 sensors but the new set up has 2 (only on the headers) What do you recomend doing with the other sensors???
I would just unplug them and wait til you get a tune, and get them tuned out. b4 you go buy 02 sims, you gotta think that the sims are like 90 bux, where a tune will be around 400 and your car will run the way it is suppost to be, b/c the headers throw your A/F ratio off.
o2 simulators (sims) send a constant voltage (500mv?) to the PCM. The PCM thinks that there are cats and the SES light stays off.
For a tune; you'd have to go to someone that can do a custom PCM reprogram and they'll turn off all the un-needed codes (rear o2's, AIR, EGR, whatever you delete.) They'll also adjust air/fuel ratio, timing, fan temp, and anything else to get car to run at its best.
The tune is the better choice and worth the extra money.
