DME issues vs repairs

[Don Smethers]

Considering purchase of a 996 with PPI showing revs, some cam deviation. Looking into cost of repair. Once legit repairs are done, can the DME be ethically reset? Repairs would be done by top shop in area, but not an authorized Porsche Dealer/Service. thanks

Exactly what are you trying to "reset"?

After freshening the engine, maybe a rebuild (don't know yet), the DME 'ignitions' which indicate over-revs would no longer be the correct information. Is it possible and appropriate to reset the DME history, to restart a clean record of the engine readouts.  thx

No.

What year?  Consider IMS history.  With too many over revs could mean car was tracked (auto cross) or abused on the street drag racing.  Caveat emptor.

Yes, very familiar with IMS conversation. This is early 2000. Part of this process would be to inspect and confirm the old double-row IMS as seller claims, or do the upgrade, in addition to the other issues. But the question is can/should the DME be reset, considering engine would be freshened and maybe rebuilt. Wouldn't do that (or buy it) it that is unethical. thx

No, it CANNOT be reset.

 

The ONLY way to know which style IMS bearing is in a 2000-2001 M96 Porsche is to take it apart and look, all other supposed methods are simply wishful thinking, so unless the seller could show you records of that being done, he is fabricating data.  Those of us that do IMS retrofits for a living would have told you that, and your PPI should have also caught any signs that the car had be pulled apart for such an inspection.
