DME programming

[spongebob]

Is there any problems involved when I change the DME programming to ROW settings.

The reason to do this is because I want to change the headers on my 2000 2,7 to a pair without catalythic converters.

Of course the car is now in Europe and wont cause any legal issues over here.

I just want a life without a cel tripped by the o2 sensors

Expecting to gain a few HP due to this headerchange and better fuel quality.

It sounds as though you are running no cats, replacing both the front cats with headers and the rears with the test pipes. If this is the case you will have issues. The DME needs to see a drop between the front and rear O2 sensors to know the cats are working, if it does not, CEL.

I believe Fabspeed claims no CEL when you use their test pipes alone. You would still have the main cats on the headers which would result in no problems. In order to run no cats, you would need to flash the DME with a new program, either custom or ROW-quotes from 986 forum.com

The rear converters are still there and making nice and clean air from my car.

But the ROW program eliminates the O2 sensors after the startup cat. Means no CEL if the startup converters are deleted

The only thing they do is to tell you that the converters are working or not and they dont exist on european p-cars

Im interested in what other problems I could run into if reprogramming.

There are no issues running the ROW program. As long as the first set of O2 sensors are present to control the mixture, the ROW program ignores the 2nd set that detects CAT efficiency.
