I found this link on here from a previous post. I am going to be installing a test pipe soon and wanted to buy the 02 simulator before I install it so I dont throw a CEL. Has anybody had any experience with this brand of O2 simulator? For only $45, you cant really beat that. Im going to call them tomorrow to find out more if there isnt a good response about it tonight. Also, is this all that I will need to prevent the CEL from coming on? Thanks for any comments!

Yes, the ECG works, I even bought it from them.

 

Just installed it a few days ago. So far, so good. One of our local club members has been using one for quite some time, and hasn't had any problems.

 

Thanks...you were the one that had posted the link in Ken's thread. Thanks for the heads up. Thanks to you too MXT 77. Can somebody explain to me how to install this and what it exactly does? Sorry, Im a noob to engine work.

 

It's a little computer-in-a-box (about 2"x2"x3/4") and it splices into your factory ECU wiring harness. It reads a few of the values from various sensors (RPM, maybe TPS) and then it generates a signal that "simulates" what the O2 sensor would generate, if the catalytic converter were installed and functioning properly. This prevents the ECU from realizing that there is a problem, which would cause it to "throw a code", and the CEL would come on.
There's a thread around here somewhere (in UTH, I think) that shows which wires in the factory harness need to be tapped/cut to install it.

 

Does anyone know if this would work on a comptech superchared 02 since I have a piggy back running into the ecu now?

 

be careful when ordering from wiredspeed.com, i placed my order on the 22 of last month and its still "back ordered"

 

My order from wiredspeed took about 3 weeks to arrive. Fortunately, I wasn't in a rush, because my exhaust took over 3 months to arrive.
