update on exhaust issues... can anyone help?

I realize. No cats here. Most people that run no cats will tie the rears up. I guess my next step is to weld in bungs for the 02 and try another set of cheaters on those. From what I have understood though was that the wide band 02s are the front ones and the closed loop 02s are the rears to double check whats going on in front of them. Thats why on other cars you can get away with tying them up.

I don't know the particulars about what parameter each O2 sensor monitors, but I do know that the ECU needs inputs. Those inputs include the O2 senors and if their transmitting bad info, or info out of tolerance, it will flag a code and the engine will not run efficiently.
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

ROW - Rest of the World ( outside of the US )

Ok so do I drive around the world? Thanks about the ROW but seriously that doesn't help me thank you.

^^ 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?

[tholyoak]

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)

Or... You could put the cats back on, the o2 sensors back in and drive a smog legal car that runs great and has no error codes. Just a thought.
