This is incorrect. Sorry.

Yes, I agree. With my ROW tune, I have only one O2 sensor per engine bank, with no error codes whatsoever (as I have already repeatedly noted in this thread).

As does every other thread regarding this topic!

Btw, I don't know what ecudoctora chargea for their services, but it's not difficult or expensive to get your hands on a working piwis 2. The hardware is made by samtec and can be purchased through a number of websites. The software can be purchased with the hardware, or downloaded from mega. No, it's not legal, but it works and is a fantastic tool to have if you're serious about working on these cars.

My car is an actual ROW car and I have written exactly what has happened to my car.

I have the circuit werks resonated test pipes as well on my '99 and love them except the occasional catless smell when stationary w/ the windows down. I've had them on for about 2 months with the O2 sensors hooked up to them and still no CEL. Also running Soul Performance's valved muffler bypass w/ oem muffler so she can get rowdy with the press of a button! :cool:

ECU Doctors website show's 499.00 for a upgrade,..but my 2002' ( I forgot ) has 4 02 sensors 2 B4 the cat and 2 After..is there still a chance I could do the 99' header system on my 02' with a plug in test only,but with only two o2 sensor's ? Thanks Frank
