    The beep could be anything from an error code to a low oil pressure alarm since the engine is barely running. Unfortunately there are few easy diagnoses on these engines. You're best bet will be to get it scanned (where error codes will show up) and hopefully that will point you in the right direction (sometimes yes, sometimes no unfortunately).

    Having said that, I imagine there is something like a thermo-time switch in there that changes mapping programs after a certain engine temperature or time is reached. The engine just may not be quite ready to run on that map yet. But test, don't guess. Get it scanned.
