Cars dont have black boxes...Cars have an ECU
I think he's referring to the secondary data logging unit that car dealers and police can check to see how you've been driving the car.
But to answer the original question... I don't know. I think our ECU logs a bit of data but I'm not sure for what duration.
I've *heard* that RSX's are equipped with these boxes. My friend tried to downshift from 5th to 4th on the freeway and hit 2nd instead. When the dealer took his car into the shop they voided his warranty because they saw ~11,000 rpm recorded for a split second before it threw a rod through the block (or so they claim... It's probably pretty easy to diagnose a mechanical overrev anyway)
yeah they likely diagnosed a mechanical overrev and then just told him "oh we saw 11,000rpm". from what i've googled here in the last 15 minutes, I can only find domestic manufacturers that use them.
The RSX PCM and many other stock PCM's will record a RPM over the rev limit. This is built into the OBDII functions of the PCM.
The 00-03 S2k PCM won't. I've been told the 04-05 PCM will, (by people that work at AHM)
The car doesn't have a seperate EDR unit. No Honda to my knowledge has had accident data removed from the SRS controller to be used against the driver, unlike some GM vehicles.
Mine does. I have a Carchip E/X installed on the OBDII port. The beauty of it is: only I know it's there and it takes all of 2 seconds to remove it and stuff it in my pocket.
It continuously records the last 3 months of driving data, including speed and RPM in 5-sec snapshots. It also has an accident mode where if it detects hard braking, it records the last 30 seconds in 1 second intervals.
