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.

I see, thanks for the info Todd!

I found a guy that can do the flash here in So cal. PM me if you want contact info.

Well I found that GIAC won't delete the cats but I have tracked down someone from Motronic that said they can set the car up with a race program that does delete the 02s and will give some performance gains at least to accommodate my upgrades and program set up for nitrous. He will probably getting back to me today. Ill update you on what he has to say.

I'm going to predict that it will be cheaper just to put the cats back on than that ECU reflash.

Ok enough already! I'm not a quitter nor am I a stand by and watch my mechanic kind of guy. I'm on this forum to get advise/ help with the 3.2L Boxster as I've only owned one so far and haven't even had to take the motor out yet. There are however many on this site that have. YES it WOULD be easier to put the cats back on YES it would be CHEAPER too. I don't give a poop about that. I am interested in making more power out of what little room we all have to play with. If I have to be the pioneer that figures things out so be it. Where the hell would you be with out people like me anyway? If you don't want to help a fellow Box owner figure out a different way, fine, but don't post the obvious just to get in your .02. To the rest of you that are actually helping thank you very much!

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.

[tholyoak]

There is no difference in the actual maps, as worldwide the Boxster runs 93 octane. If your car runs on 91 now, then switching to the ROW program will not cause any problems. As for the testing in California, I doubt it will pass as the readiness codes are different with the ROW program but that is just a guess. You will want to select the EU2, manual transmission program when you have Loren remap the DME.

Thanks Todd! Tool Pants is playing with the same thing and unfortunately is subject to the same California smog requirements. We'll see how it goes for him, but he brought up the same issue with readiness codes... He also noted that I'll need my car's DME programming code, which I don't have.
