update on exhaust issues... can anyone help?

^^ 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?

[tholyoak]

There are actually a few 'ROW' programs, but I assume the one you are interested in, is the one that doesn't use post cat sensors. This obviously only use pre-cat sensors to control the mixture, ignores the need to depress the clutch to start the car, doesn't use the air pump for cold starts. Also it is virtually impossible to get a CEL as the tolerances are much greater on the ROW program. Those are the differences off the top of my head.

In earlier Porsches, the engines were higher compression and used higher octane in europe and thus used a more aggressive map (timing) than the USA/Canada program. Therefore a performance advantage was gained. This is no longer true, at least on the Boxster.

Todd, I appreciate all of your input here! Do you see any problem with running the ROW program you described on the crappy 91 octane gas in California? Also, can you tell me specifically which program I would load onto my 2000 Boxster S (manual transmission) DME to get this ROW setup? Does the program have a file name or title that I can go by? I'm going to see Loren in a couple weeks and I'm sure he could do this for me with his PST2, if he knew which of the programs to load.
