I hope someday a computer nerd will develop some software that will allow the Boxster the use of running with no cats (off road use only officer ). Sounds simple to me.
So are there no computer flashes that can correct this problem?

Ya, its called the european tune. Just flash it with a ROW computer and it doesn't read the cats. An australian member runs catless because of this IIRC

I've been around here for awhile and seen the abbreviation ROW before... what is it?
How do I go about doing this flash tune? Can I change other parameters. Can I do the tune then chip the car? Suppose I have to send my ECU out

As you already know that ROW stands for "Rest of the World"... to elaborate on this term for you, There are 2 types of boxsters... US spec Boxsters, and ROW boxsters.... US Spec boxsters have tighter Smog requirements and less aggressive/softer struts, springs & swaybars and settings than the ROW Boxsters.

Does that make sense, ROW Boxsters are sold EVERYWHERE but the USA.

You WANT the forward O2 sensors in the exhaust stream. This makes corrections in mixture during closed-loop operation. Don't use a cheater on these, use a normal bung.

For the rear sensors, if you can't get a reflash, you can replace the sensor with a circuit that tricks the ECU into thinking all is well. I've posted it here before if you're interested you should be able to search for it.

^^ do you have any advice on who would be able to flash it with the ROW software? I mean the dealer (i have a good relationship with), would they be able to get the ROW software, or do they just have access to the US software?

All the maps are in the PST2/PIWIS, anybody (like myself) who has these tools can reflash the DME as long as the DME code is provided. I doubt a dealer will do it for you, as it is not legal for street use to run the ROW program here in the US.

You don't 'chip' these cars, they are reflashed with new maps by aftermarket tuners the same way the different factory maps are flashed, through the OBD port. Thus if you put an aftermarket 'chip' in there, it will overwrite your ROW map. Thus you would need a 'performance' map that also ignores the after cat O2 input.

Has anyone had their car dynoed after converting it to RoW spec?(Preferably a 3.2L)

As I stated in my PM, there is no performance gain by converting to the ROW program.

Todd, what differences are there from US spec ECu to a ROW ecu? would you happen to know all the differences?
