Empire Performace O2 sim

Anyone run this thing? How is it? For those who do run it, has it thrown any codes after installing it?

My problem is that the truck threw a 0420. Bought the URD O2 sim and it ran fine for about a month or so with no CEL. THEN, a 0136 popped!!! Emailed Gadget and we deciede to take it out and run it to see if anything pops. STILL AN 0136 after everything we've tried........running it with the URD sim, running w/o the sim, checking and double checking connections....it still pops.

Heard about the Empire O2 sim. Supposedly it can be ran without an O2 sensor. I don't have emissions testing here so no worries on that part.

My question is........is it worth buying this O2 sim than over a NEW O2 sensor?

I am pretty sure that my O2 is shot.......she's got 155K on it!!! 2001 Taco Prerunner V6 auto...

 

I installed one two months ago after dealing with the URD sim, and have had no problems or CEL's. Easy install, wished I had bought the Empire sim in the beginning and saved myself all the hassle.
