ROW vs US Spec ECU Flash

I was trying to come up with a definite list of the Pros vs Cons of a ROW vs US spec ecu tune. This is what I have so far...Anything else? Any power differences?

Pros:
-No secondary O2 monitoring
-No secondary air injection monitoring
-Not required to put the clutch pedal in prior to starting

Cons:
-Only one bank is monitored for cam timing

On the facelift cars the rear lambda is monitored and it can trigger the CEL but you can run fine with the CEL on. In any case you can remap them out.

On a 7.8 DME ROW flash, not only isn't the SAI monitored, it is not activated. I suspect ROW cars do not have SAI.

Now this ROW flashing is getting intresting
I live in Finland and have US spec Boxter Base 986 (2001). What could be the place to get the ROW ECU Flash done? Probably not at the local Porschs dealer... Any ECU programmers or...?

In my experience, you need to obtain the reprogramming codes for your DME (ECU) from your local dealership (which is free if you can get them to do it) or pay a shop that have the needed tools to unlock your DME. Whichever route you go, once done, you can re-flash your DME to the stock ROW tune using most PST and PIWIS tools with the ROW files (or pay a shop with the tools).

Certainly no SAI on UK 986.
Funny that in Finland you get a US spec car when most Boxster were made in Valmet.

This car was originally sold in San Diego... Few years ago it was brought back to home as the owner moved here

Take out the existing DME and buy a used one (they’re not expensive) and ask the dealership to reprogram it for you (ask if they reprogram used DME before hand). If they simply assume that the car is ROW spec without checking, this might work out.

$80 for used DME from eBay (had to buy one) and my dealership charges $200 to reprogram (asked them in the past)

I've reflashed DMEs in less than 15 minutes....The hardest part is entering the codes without a keyboard. I suggest you ask (in person) at your local dealership for the cost to do this.
