October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Engine mount control: Function

The changeover valve connects the engine mounts to the vacuum supply. When activated by the DDE master control module, the changeover valve switches vacuum to the engine mounts which in turn switch to "soft".

The engine mounts are activated as follows:

From "soft" to "hard" when 1050 rpm is exceeded
From "hard" to "soft" when 950 rpm is not reached
