Zakowsky, you're a genius. Yes, Cobb did reversed the numbers and that threw me off. I originally thought it was a coil pack issue when I was researching the reversed codes. You can see from the Vehicle Diagnostic Report below that the 2 main fault codes were exactly as you said.
Lol! Thanks but that was just from reading the posts from the knowledgeable people here so much since my own Porsche's seem to be broken half the time!

Good luck with the repair.
Thank you! I feel so much better after you pointed out the fact that Cobb had the numbers reversed. The reversed codes caused some members to question the validity of the diagnosis. I feel better knowing we're on the right track eventhough it's an expensive fix.
I would’ve started the thread with that. Now it makes sense.

The Durametric (not sure which version, but at least the version I am running on my laptop) has the same code-reversing issue.. just FYI
i am using the semi latest durametric v6 for the last couple of years now and am not getting reversed codes. the codes i have pulled have match what my shop gets with their version of PIWIS.

I just checked, I'm running version 6.3.2.5. I know at one point several years ago folks had let Durametric know about the bug but they had not fixed it as of sometime in the 2018 time frame. Good to know it finally got fixed.
I have read that Cobb reverses the numbers sometimes, so if that is happening it becomes
P0607 - Control Module Performance, so a problem with the ECU.
P0603 - The Powertrain Control Module (PCM) has failed its own Keep Alive Memory (KAM) self-test.
If this was caused by flashing a tune, I think many people would be interested to hear this. Sorry this happened to you.
I have been having this problem after I got my Cobb v3 and added a stage 1 file.
I heard everytime you flash with Cobb...it resets some kind of timmer in the ECU and dealers and smog stations can tell you flash your ecu . Does anyone know about this ??

Yes. In my experience when you flash the ECU with a COBB tune file, it will reset certain emissions monitors; similar to clearing codes. One you have a couple of drive cycles, then everything should be back online. I don’t have experience with any other tuning platforms so I can’t say if this is a COBB thing or something the ECU does with any/all tuning platforms. I would think the latter as your basically resetting the ECU.
ECU’s have a flash counter. Every time you flash your ECU this will create a log of the flash. This is how dealers can determine if you have a tune. Also some ECU’s have a flash limit, don’t know if Porsche does. Some tunes can reset the flash counter back to 1 but don’t know how f any tunes for Porsche does this. I know on BMWs most of the tunes would reset the counter because they had a limit of 100 I think. Also, every time you flash your ECU (or reset any CEL code) your readiness status is also reseted. To get the readiness status back, you just got to drive the car around for a bit. Sometimes it takes 30-45 minutes, sometimes like 200 miles.
Is anyone here familiar with the process of ECU replacement? I'm getting mixed answers from my Indy and dealer. Long story short, I tracked down a new ECU/DME from Porsche and had my Indy swap and program. They were unable to complete the work and recommended I take it to a dealer and have it done. My local dealer said the ECU should come with my VIN already program from the factory. While I was told the ECU comes blank and the software is then downloaded and programmed. I appreciate the advice, thx.
TV997 your local dealer is incorrect. Tell them that you bought the ECU from Marin Porsche or Sunset, or Suncoast and it shows up in a brand new box. The dealer will have to go online with the PIWIS connected to the Porsche mainframe.
Many tuners can clone a ECU. I have rebuilt/revived several.
Keep portable battery jump boxes away from this car.. The high inrush current can create wreck internal ECU drivers, EPROM and CPU's...
I Doubt the COBB tune is the culprit, anyway, the ECU of a 997-1 is easy to clone with one bought on ebay
I did it using a KTAG and the ECU on the bench
So my DME adventure took another turn. I was able to convince my local Porsche dealer to put in a new factory DME for my '08 turbo tip. However, after programming the car only start out in 3rd gear from a standstill. It normally starts in 2nd before it went faulty. I have Fabspeed 200 cell exshaust, IPD plenum and Y-Pipe, BMC filter along with a GT3 Throttle Body. Could the increase in air flow caused the car to start out in 3rd? If that's the case then I'm assuming it's expected and I just need a custom tune to smooth it out. Does anyone have any idea? Thx.
