I'm getting an engine exchange done in my 996 (to a slightly used 997 block).

Suggestion

But its imperative that when the new engine is installed that the ECU is cleared with a "handover" or whats sometimes called a "system reset".

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm getting an engine exchange done in my 996 (to a slightly used 997 block). What happens to the information stored by the DME when you do an engine exchange? Does it keep all the info (such as over revs) on the old engine and then append it with the info on the new engine? Does it reset? Or, does the new engine's DME info port over?

POST 2Original post

Unless someone reprograms it, the DME cannot tell one engine from another. It only sees the same sensors and actuators on the new engine. In other words, the old DME info on the engine will continue to be updated as if the engine was never replaced.

Hope that 997 transplant is compatible with the existing population of sensors and the 996 engine controller.

Guess we'll find out soon. Keeping my fingers crossed, but I'm sure my mechanic knows what he is doing.

POST 7Original post

The DME doesn't know the engine has been changed. Because of that all stored info is there and the only way to remove it is to exchange the DME and reprogram it. But its imperative that when the new engine is installed that the ECU is cleared with a "handover" or whats sometimes called a "system reset". If this isn't done, the adaptive and etc may have adjusted to the failing engine, and will enrich the new one in the same manner. That can cause issues. When we install an engine, we perform a system reset before the new engine is even started the first time. We want the adaptation process to occur as fast as possible with the new engines and for none of the old fuel trim and etc to remain in the DME.
