I recently had a 2000 3.2l Boxster S engine put into my 1999 Boxster. The car currently runs, but wanted to take advantage of the extra power by using a 3.4l 996 flash for the ecu instead of the 2.5l is currently loaded. My mechanic and the local Porsche dealer have been unable to do this. The car has all the standard electronics for the 1999 Boxster and a 3.4l mechanical throttle body. I have read that the ecu can be flashed with the 3.4l software used for the 996. Is this possible? If so what steps need to be done?
