New DME, throttle response feels different

The DME just got replaced under warranty. The minute I drive off the lot, I notice the throttle feels different. Would a new DME change the E-gas throttle map? What the heck does the DME do anyway?

it is learning & adjusting,,,

Drive it a little more, she will be fine.

Thanks. What is the DME learning or adjusting? It's not like an automatic where optimal shift points can be "learned", is it?

smackboy1,

Sort of!! My understanding is the Porsche learning algorithim uses 5 "drive cycles" that allows the DME to look at the various O2 sensors performance ( and tolearances) as well as the MAF characteristics t ooptimize the engine performance ( and emmison parameters).

As others have said, drive it for a few days and you be back to better tha nnormal with your new DME.

Good Luck!! demosan :cheers:
