Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suspected cause

It looks like there was a single over-rev event at 100.0 operating hours - most likely a forced downshift to a lower gear at a little too high of engine speed.

As was recommended by some kind folks on this board I requested an ECU print out of the engine.

Leading evidence: 'forced downshift' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'forced downshift' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Recommend by some kind folks' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

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 1Original post

As was recommended by some kind folks on this board I requested an ECU print out of the engine. A couple of questions: 1. Operating hours counter reading at overspeed range - range 1,2 and 3 are all 100.0 h (why are they all exactly the same?) - range 4,5 and 6 are all 0.0h 2. Ignitions at speed -range 1 = 249 ( I assume this is x 1000) - range 2 = 7 - range 3 = 1 ( am I correct in believing this one to not be a concern?) -range 4,5 and 6 = 0 Any feedback would be much appreciated. Cheers, Rob

You might take a look at this (although it goes off topic along the way) http://www.planet-9.com/cayman-tech/14265-time-sensitive-question-overrev-issue.html

POST 3Original post

My :2cents: It looks like there was a single over-rev event at 100.0 operating hours - most likely a forced downshift to a lower gear at a little too high of engine speed. The single ignition in range 3 is probably not much to worry about.

This might help you decipher those digits: The Cayman Club - FAQ: Cayman Technical Data

POST 5Original post

KC-CS, Thanks for that. That would make sense. I just received the letter from Porsche stating that nothing on the report would void the warranty... I am now a Cayman owner!!!!!!!! YAY.

POST 6Original post

Way to go trooper7. It is nice to think we helped you make an informed and careful decision. Welcome to having fun with your Cayman.
