Will an O2 simulator that alters the signal for check engine light interfere with anything the flash does to the ECU? I have a test pipe that's giving me the cel and want to make it go away. Any advice?

 

nope, i have a mail-in flash and a an o2 simulator and have had no problems whatsoever

 

go get yourself a pair of 18mm spark plug anti-foul, bore one of them to 1/2"ID. dont mess around with that O2 simulator.......some dont work...

What does that mean?

 

when you buy them, you'll understand fix works great, no cel in 8 months since I did it. It only cost $5 too, alot cheaper than simulator

 

Search under mechanical o2 fix. Will cost you less than $5 and will get rid of your check engine light

 

It works by moving the rear o2 sensor out of the stream just enough to give a different signal than what the front 02 sensor is reading. This tricks the ECU by thinking the Cat is working by a change in the reading of the exhaust gases. The rear o2 sensor is just there to make sure the Cat is working basically.
