Having said that and being a 335 owner and Master Tech myself, I know of a few guys running Procede (hint hint) and the diagnostic equipement has no idea the procede is on there. I've checked from every angle available in the diag equipment and found nothing.

Which dealer are you at?

These are FIFO systems meaning first in first out so it stores information for a period of time then purges it for newer information. The only questions is how big this storage is before they begin to purge the information.

So if normal operation of the boost is 8 to 10 Psi and now your at 12 to 15 this information is probably stored and they can see it when then hook a computer up, however, if your drive for a few days and never get on it and hit the higher boost levels then most likely the higher boost levels would get purges.

One more point, depending on the system they may record and store max and min values and never clear them unless an new max and min show up. So if BMW is doing this, they will see the higher boost numbers that were hit. Many times only way to clear these is to pull the power for a period of time and the memory get wiped.

Lastly, be warn most all car companies are looking to put in Blackboxes into cars with a small hard drive which will record everything the car has see and done.

I have an e46 m3 that went through a couple motors. before they would replace them they had to check the compute at BMW plant to make sure the motor had not gone above red line. it's an smg so there was no chance of that. but more to the point they told me the computer monitors how much time the motor spent above 7900rpm(my car was 10 sec). BMW's not stupid and almost every turbo car has had available aftermarket software. they new the 3.0 twin turbo was destine to be tuned. I would not doubt that the computer has a monitor to record high or over boost levels. something that would not be over written. just my thoughts on it

But doesn't the Proceed interupt the boost signals and report normal boost to the ECU? The ECU will never see high boost.

Not the case with a reflash. Who is selling a reflash so that 54 cars have been flagged?

So that reaffirmed that nothing gets stored on the DME from the PROceed.

That being said, a flash program that gets stored right on the DME will most assuredly store all conditions that the car sees. Plus if the dealer reflashes your DME back to stock, you just lost your programming and have to pay for it all over again. Sucks to be you.

Most times, the distributor will reflash you for a $50 fee or you can send the ECU in to the tuner for reflash. I know this from the VW scene - APR and GIAC were the main players and reflashes were common when software updates from VW came out. Still sucks and the interceptor route and flashing each have their own set of pros and cons.
