Question on Boxster 911 Engine Swap

[gus969]

I have a 1997 boxster with a 1999 911 engine Kelly Moss conversion car.

I have the following two codes:

PO453-tank pressure sender

PO 447-shut off valve activated

The car does not have a pressure sensor on tank or a purge valve on canister.

I understand in 1997 the cars did not come with these.

Is there anyway to get these codes cleared?

I believe the only way would be to have the software in the DME modified. Porsche may be able to handle this, as I know BMW does it for their vehicles.
