o2 simulator or not?

[ekim55121]

any one on here think its a good idea of just getting an o2 sim instead of just getting new o2 sensors? I know I have a bad sensor because im getting realy crappy gas mileage like teens mabey and its just getting worse last tank i got like 19 a gallon and i used to get like 27 or more. but yeah i got an o2 sim box for like $20 and it works good know that much my friend used it on his camry but since its gone its now mine. so let me know what you peeps think about this lil gadget

They are great for the rear o2 but you can't use one for the front. The rear sensor just measures catalyst efficiency. The front one has to measure a/f ratio so you need it. I have on on my wifes car and it works great. (direct fit o2 for a mazda is $268)

neither of my 2 sensors are heated i forgot to mention that i have a gen 3.5 i4 so yeah im thinking that it might work just fine, its a 4 sensor simulator and i only need 2 sensors simulated, it has warm up mimicing and some other cool features so imma see what this yeilds for me and let you guys know if it dont work on the main on ill just replace it since its only like $60 and use it for the secondary one.

any one else have any ideas or suggestions
