How important is break in ?

Doesn't the ECU track nearly everything anyways? I always thought it logged the number of full throttle applications + duration, or is that ONLY prior to crashing into a concrete barrier?

Only driver for 12 lol but yea I fkd up my rotors big time doing it a few times. Expensive lessons but so far have put another 30k on the car since that issue and rotors are still good.

I think it's on the higher super cars for performance tracking. I think McClaren or porche did that to the competitors and left a note cause they baught a car and they saw it was put on a test track

You are probably thinking of the Event Data Recorder. What it records and how long it keeps it is up to the manufacturer (unless the law has changed recently). The FSM may have info on how Nissan does it with the 370Z.

Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

That article gets trotted out every time this conversation comes up. The guy provides next to no evidence, has a website that looks like a bad myspace page and interrupts his article multiple times to try to get you to look at a list of his 1000 favorite music videos. He very well may be right, but he's not helping his credibility with his presentation.

The PCM is monitors all kinds of things while the engine is running and even when not running. Things like fuel rail pressure, engine coolant temperature, ect. For instance when a car over heats a DTC is set and the check engine light comes on. Then when I scan the vehicle, freeze frame data will also be present which shows me the temperature of the coolant.
