I've actually made my own 'mil eliminators' in the past. Haven't had a problem --

Every one of my last few vehicles all have had oxygen sensor simulators. I typically remove the catalytic converters to improve my gas mileage. You can only install the simulators to replace the rear oxygen sensors. You cannot use 02 simulators in anyway for the front oxygen sensors as The ECM uses the sensors to adjust your engine's Air/Fuel ratio. Contrary to what some people might say the ECM only will throw a CEL for the rear 02 sensor if the voltage is to high or to low , if it dwell time between low and high is to long or short , and if the 02 heater circuit is open, too many amps or to little amps. I know this because I've hand built the 02 simulators used on my vehicles. It really isn't the rocket since that some people make it out to be. In the future you may say look up tables to check between the rear and front 02 sensor data but do you really think companies that will not even use bolts where they can get away with it are going to splurged on ECU memory and programing, I think not...

You live on the moon?? Removing emissions devices is a FEDERAL law. Just because you don't have testing doesn't make it legal.

The ones I have they don't make anymore. You can buy o2 Simulators on eBay though, they basically just pull the sensor out of the direct gas path giving it a good reading. You can also just put a resistor into the plug in if you know what one you need.

There is a bypass kit on ebay that is a inline resister that should work. Make sure you are resetting the check engine light when testing these out.

Would you mind sending me some instructions and parts on how to accomplish this for a 2011 F150 3.5l ecoboost? Looking to perform this option on my truck and by myself, just unaware of the procedure and hardware I my need. Thank you in advance!
