flash
I am no expert. In my case I installed a 3.4 996 motor in my 98 Boxster (986).
My 986 (2.5) DME could was not programed run the 3.4 996 motor without a re-flash.
I had two choices:
1) a USA flash that would use the existing secondary air pump and related vacuum tubing. or
2) a ROW (rest of the World) flash that would allow me to remove the secondary
air pump, etc.
I chose the second.
When I was at the Porsche dealer trying to get them to turn on my reciently installed cruse control. They made the comment that the DME was locked.
I assumed that it was done by the individual who did my ROW flash in order to keep the DME from reverting back to the original 2.5 USA flash should the battery be disconnected.. That assumption could have been incorrect.
Can anyone comment???
