URD Headers / O2 simulators and tuning knowledge

Nope. It was from a company called Empire. Empire USA I believe. Shocked me the first time I saw it because the sensors were "missing". Yet just replaced by the box.

 

I see now... some chatter about it on CT, someone was emailing them in 2007 and ever got any reply.

Sad.

 

Short lived product but better in my opinion.

 

How did you fix your 430 code did you use a spark plug fouler adapter or did you go a different route? I have the same setup DTLT stock y pipe o2 sim and 420 and 430 codes intermittently.

 

Resurrecting this thread. Wanting to get long tube headers for my 2015 V6 and need to know if anyone found a fix for the CEL's since the simulator doesn't work?

 

Some members have had luck running a j-bung adapter and the simulator. Supposedly it works. This is what I plan on running too. Check out this discussion:

I have been running the jbung and urd sim for over a year and the light has not come back.

 

Thank you I just read through this one and will give it a try.

I saw your posts that the previous guy posted. I just ordered a set of those j bungs now actually. Thanks for the help.

 

Currently dealing with P0420 / P0430 after DTLT install.

What if I were to use an antifouler and weld it completely shut, then slowly drill bigger and bigger holes until they passed?

Anyone tried the "5$ 02 sim" with diode and capacitor as found here? : Lots of discussion in that thread how URDs $150 02 sim is just that in a fancy package, can anyone confirm or deny this definitively? Does URDs REALLY help to calibrate the front sensor?

 

I took one apart, some years ago. It has a circuit board in there. More than just a simple diode and capacitor. For whatever that is worth. By all means though, if that thread has directions and true positive feedback, give it a shot. Let us know how it goes.

 

Thanks for the response! Will chime in again when I have an outcome.

 

So my solution was just to stack 3 non-foulers on each 02 sensor, the center non fouler I welded shut, then proceeded to change the diameter of the hole in that middle non fouler with a drill bit.... it took me about 3 or 4 different test holes but I ended up at about only a 1/8'' hole and I haven't had the code come back, and nothing pending either. This is the same concept as the Vibrant J bung with the adjustable inserts, I was just on a time crunch for a trip Im leaving for in a couple days. I spent about 15$ for 3 sets of 18mm non fouler's from oreilly. No 02 sim needed as far as I can tell with this method.

 

Give us an update on this, after about 120 miles or so. 50-60 should have every system ready, so that will be over that amount enough to get a better idea.

 

Will do. I have already driven enough for all the systems to do their thing and I passed smog yesterday. I'm leaving on a ~1500 mile round trip with lots of varied driving so that should be a good test.

 

Awesome!

 

Figured Id pop back in here for an update for anyone that happens upon this thread like I did . Going on about 7 weeks, and probably around 700 miles of varied driving. Still no CEL and nothing pending either. No perceived negative impact on MPGs or otherwise..... was a great alternative to the O2 sims for me.

 

You sir just gave me an idea, for another project.

 

Go on...
