Don't know why this hasn't been mentioned, maybe no one is aware of it, or doesn't care.

2007 and 2008 Z06's now have an EVENT RECORDER. This recorder keeps track of every time your PCM has been changed/reflashed.

I've been thinking about a tune on my '07 Z06.

I talked to my tuner that tuned my '04 Z with HP-Tuners, and was 100% satisfied with the tune.

Just called him to schedule a session for the tune, he informed me that if I was concerned about my warranty, I needed to know the facts.

He said that all the 2007 cars have an event recorder that identifies each time the PCM is re-flashed, and "some" dealer's have not honored the engine warranty when problems occurred. He also said cars before 2007, didn't have this.

Does anyone know about this?

Here is some information from HP-Tuners forum

This is all starting to make sense to me now.

GM has put a feather in its hat!

Five year 100,000 miles warranty, more intrusive torque management.

GM knows that any worth while modifications involves a "tune", and that's where the buck stops here.

GM's worries about engines, trannies, rear ends, etc. should be a thing of the past as far as warranty work.

Got to give GM credit

I don't hide any thing from my dealer, And he does not lie to me. He knows I race the car and he has not failed to fix any thing that has broke. The car was made to race from the factory, and warranted to do so. But to expect them to fix what you have built in to their design is crazy. So if you mod it you better know what your doing and warrant your on work.

Could you buy a new ECM and have that reflashed. Then put the old one back in if you have to take it to the dealer?

Yup, probably could. But they will also probably know that you replaced ecm with a different unit and may want to know why!

I would look at the service manual. If there is NO EDR then the 1st post in this thread is misleading.
So, rather than speculate or get caught up in some tuner's bs line, you need to look at a service manual for an 07 or 08 and see if that device is there.
If it's not there then you can chauk it up to another forum boogie-man story.

This is a quote from the Owner of one of the most respected tuning systems in use, HPTuners.

"GM can verify a tune on newer vehicles if they check the CVN.. They have the system in place for the newer vehicles but its up to them to use it".

Why don't you get a service manual and let us know for sure :thumbsup:

From pg 464, 2007 Owver's Manual:

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles,
has a number of sophisticated computer systems
that monitor and control several aspects of the
vehicle’s performance. Your vehicle uses on-board
vehicle computers to monitor emission control
components to optimize fuel economy, to monitor
conditions for airbag deployment and, if the vehicle
has the Anti-lock Brake System (ABS), to provide
anti-lock braking and to help the driver control the
vehicle in difficult driving situations. Some
information may be stored during regular operations
to facilitate repair of detected malfunctions; other
information is stored only in a crash event by
computer systems, such as those commonly called
Event Data Recorders (EDR).
