I notice you had a number of ignitions (over-revs) in range 2 & 3 (and 1 in 4) - did your DME flash also raise your rev limit cut-off?

 

It certainly was supposed to. But without knowing what the limits are to begin with I have no idea when these over revs happened.

Which begs me to question what the rpm's were when the over revs happened? Is this info shown on the FIWIS Vehicle Analysis Log?

Here is a recreation of a document given to me by a Tech at a local Porsche dealership. Yes, this is real. He said this applied to the Cayman as well and was given to them during training on diagnosis issues:

There are several stages of imminent disintegration for the new 997s that will be evident in the log print out.

RPM Ranges:

1 - RPM Achieved 7300 to 7500 Likely Result Oh, behave Abuse
2 - RPM Achieved 7500 to 7700 Likely Result Ooooh! Abuse
3 - RPM Achieved 7700 to 7900 Likely Result Ouch! Abuse
4 - RPM Achieved 7900 to 8400 Likely Result Dammit! Did you here something pop too? Possible Damage
5 - RPM Achieved 8400 to 9500 Likely Result I’ve been hit! I am losing power! Definite damage
6 - RPM Achieved 9500 to 11000 Likely Result Live grenade! Take Cover! Going, going, gone!

The tech told me that Zone 1 and 2 will not likely effect warranty, but Zone 3 and above certainly would.

I had my car tested and after multiple track days and hard driving I had zero Zone 3 and above hits. YMMV.

 

Unfortunately, they record data by engine hours, rather than mileage or date, so for example: your Range 4 over-rev occurred at engine hour 246.3, and your most recent Range 1 occurred at 265.7 hrs. If you know what the current engine hours is (I didn't see it on the print out) then you might get a rough idea of when they occurred.

Range 1 over-revs are not uncommon if you hit the rev limiter or redline under normal circumstances. I don't think you should be hitting the higher rev ranges unless the DME re-flash is allowing it, or you missed a downshift.

 

Yeah without knowing when the car was flashed vs. when the overrevs occurred it is impossible to say if the flash had anything to do with it. It could be a missed downshift at some point as was already pointed out. I have seen unmodified cars have misfires as well too, sometimes cause by faulty coil, bad fuel, etc. While this information can potentially be showing problems with a flash, I don't think it is conclusive by any means. Having a full report before and after would have been more telling.

 

But without knowing what the limits are to begin with I have no idea when these over revs happened.

I meant to say "I have no idea at what RPM's the over-revs happened". If the flash raises your red-line doesn't the flash also raise your over-rev limits?

All over-revs were post DME Flash. But I have to admit the over-revs was operator error, at least the stage one. It does rev up quick in first gear! Stage two was and hopefully the only mis-swift, stage three and four were just flat out trying to stay ahead of a very fast cobra, mission accomplished.

 

I meant to say "I have no idea at what RPM's the over-revs happened". If the flash raises your red-line doesn't the flash also raise your over-rev limits?

I wouldn't think so.

What do you mean by "failed state inspection"? Smog check?

 

The below PIWIS report shows unexplained misfires. These misfires occurred hours after a failed state inspection by the dealer. Dealer tech is confident the FVD Brombacher DME flash is the culprit. FVD has admitted others having the same problem. I have no tolerance for these types of malfunctions. This is not beta-testing! FVD is working on the problem but I have lost confidence in the product. If I lose confidence in something, that something goes away, by either a refund-return or the trash-man.

Perfectly good reason to switch to the softronic race plenum without losing money on the flash.

Cayman Cope-
My name is Mark and I run the technical department here at FVD's US office. Sorry to hear about your failed inspection. It has come to my attention that apparently you are displeased with our programming and are quick to point the finger at that as the root of the problem. Perhaps a little more information on what else is installed on the vehicle or how it performs, or doesnt perform, may help to clarify whats going on. Information such as what kind of exhasut- if any- is installed on the vehicle and why its not passing inspection. According to your above posted quote, FVD has admitted to this being a known problem and that we are working to correct this issue. I can assure you no customer, yourself included, has ever contacted us in regards to this issue with our ECU programming, as if they had- I am the one who would have handled it. The only one that jogs my memory is through one of our dealers and that vehicle failed state inspection since it would not pass cat efficency ready status and has another companies exhaust with race cats installed on it. I can also assure you that our 987 programming is not beta testing and have sold quite a few to very happy customers across the globe- and as a company have been tuning ECU's since the 1980's. I would be more than happy to discuss this matter with you in person as I do not sit on the message boards during the day to answer posts. I can be contacted directly at 954-977-7130 at X 27 to further answer any questions you may have or to work through this issue on your vehicle.
Kind Regards,
Mark

Mark,

I am getting 3rd hand information, possibly 4th hand info, all from the dealer, so in your defense I apologize for placing absolute blame on FVD.
