"legally" being the key word.... I guess i'll start investigating to see if the recording function can be shut off...big brother needs to stay the F out of my car.

If they illegally access the data, you can probably sue the everloving crap out of them. Technically, I believe it is also a criminal offense and could be prosecuted under "hacking" laws.

What that has to do with what you were saying:

There will come a time when the dealer won't have to ask you anything. Indeed, maybe we're there now.

Right, but the OP said something about following a snow plow in the snow and the dealer goes "oh shit hydrolock". How does this black box know it's snowing and your following a snow plow?

As long as you're not being negligent with your speed and you haven't modified the car what can the black box show that would void a warranty claim?

Although we're a bit off-topic now, I'd like to point out a very important paragraph in the BRZ owner's manual concerning the EDR for all you paranoid people:

NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs. No data is
recorded by the EDR under normal driving conditions and no personal data (e.g. name, gender, age
or crash location) are recorded. However, other parties such as law enforcement could combine the
EDR data with the type of personally identifying data routinely acquired during a crash investigation

If I may add one more tidbit to this side-conversation...

A few years back I was taking my BMW in to be serviced and I made a comment about how much technology had advanced when the "technician" took my key, stuck it in a reader box and was able to get all kinds of data off of it including ECU logs!

He told me about a warrantee claim that was made a few months earlier over a brand new 7-series that a dad bought for his son. It was returned a few months earlier with a blown transmission. The "technician" said when he inserted the key from the car, he was able to tell that the car was moving at 70mph at full throttle when the car was shifted into reverse. He was quite proud of himself for being able to deny the warrantee claim due to abuse.

Anyway, just thought that I would share.

@Blaine&Andrew:

I am not an expert on this. However, my understanding is that a Congressman in Massachusetts and the ACLU are upset about EDRs, and they want to make sure there is legislation to protect the consumer because, as pointed out above, you own the data. Also, because of First Amendment rights.

My understanding is also that the EDR is like a "black box" recorder on an aircraft. It is logging data of a kind above and beyond error codes, including what's going on in the cabin (e.g., whether or not there is a passenger sitting on the passenger seat).

Could they tell there was a snowplow on the road at the time of the incident? I don't know. Can some cars tell where the curb is and park themselves? Yes.

EDRs basically record telemetry in the event of a crash; or at least that's what we're told they record. Some cars record different data, as evidenced by the BMW 7 series warranty claim above.

In any case, you don't have to be a paranoid conspiracy theorist to want to be the one who controls the data, i.e. where is goes and what it's used for.

I very much agree, but let's talk about rod knock and the dealer trying to screw this guy instead of EDRs.

LOL,

I still don't understand what the OP mentioned about the piston hitting one of the injectors.....

The DI injectors are located between the intake valves in a recess of the head... I don't see how it could get hit unless there was debris inside the chamber.. then again, i don't think we have a cross section view anywhere that shows if the tip of the injectors protrudes into the cylinder...

I understand if the bearing is worn enough for rod knock that there is extra slop in the travel.. but there should be enough squish area that nothing would hit the injector...

[pozer]

To me it looks like the DI might have a few mm overhang but I did not see it myself so I can only guess.

Yeah, I was thinking that with a bad rod bearing, there may have been enough slack for the piston to kiss the injector tip.

Great graphic. Many thanks for that.
