ROW DME vs. OBD2

[ivass]

I have been trying to find a comparison of the OBD2 and ROW DME programs. Does anyone know where I can get this? Thank you in advance.

I would rally appreciate some input on this.

A specific point of interest to me is weather the ROW DME trows out a CEL if you use a cat bypass pipe. Has anyone tried this? I read somewhere that ROW DME ignores the secondary O2 sensor (for CEL purposes). Is this correct?

I know that many people use cat bypass pipes, how do you deal with the CEL?

Will the fuel map in the ROW DME give me a bit more power?

Thanks

Euro-norm 3 = only 1 sensor before cat. Euro-norm 4 = 1 sensor before cat. and 1 sensor behind cat. The secondary sensor is active and trows fault codes. ROW DME is programmed to use 98 RON fuel ( 95 RON is the lowest quality available and already less powerful by intervene knock sensor on full acceleration )

You don't state the year of your car, but if it is a 3.6 you have 4 programs to choose from (OBDII, ROW (Euro2), EOBD (Euro3) and Japan and the X51 and tiptronic variants of these).

If you run the Euro 2 (ROW) program it uses only the precat sensors for fuel mixture. Post cat sensors are not used as these measure cat. efficiency. The Euro3 program is similar to the US OBDII program in that it uses all 4 sensors. I have never seen a CEL on a ROW program as the threshold on the ROW program is much higher than the Euro3 or OBD programs (ie the fault has to be present for a much longer time).

I don't believe the maps are any different for US and ROW as all the technical data I have is stated for 98 RON/88 MON for all cars worldwide. This is equivalent to 93 octane here in the US and Canada.

My car is a 3.4L, 1999 C4, EGAS, DME 7.2, 6 Speed. So I guess I need the ROW (Euro 2) to get rid of the CEL. And as long as I use US 93 or better I am in good shape, correct?
