all the manufactures have master scanners, they can go in and tell you every time you were speeding, not wearing your belt, and anything else on that truck that has a sensor since the day that computer was brought on line, GM's and Ford's are the same way, a good friend of mine is dating a woman that partially owns a Chevy dealership (her dad and sister own the other parts), and i am also very good friends with the head service manager (he rents my farm), he stood right in the shop and watched the GM guys scan a trailblazer cause a woman was threatening a law suit against GM because she said some of the safety "features" didnt work properly in the rollover crash she was in cause she was doing the legal speed limit......the scanned it, politely smiled at her and told her to remove herself from the dealership property or she would be escorted off the property, she was doing well over 70 MPH, wasnt wearing her belt, and never used the brakes........plus one of my college teachers was a researcher/driver at the GM test facility in Mesa Arizona and went very in-depth on how the whole system works along with ALOT of the cool stuff most people dont know about their vehicles.....

 

The computers have a freeze frame that records what has happened in the last X amount of time before something happens. That is common knowledge. The state police use the same thing in traffic acident investigations. It does not have record of everything the car has done since the computer was brought online, if so you would run the small *** computer out of memory fast...

 

Ding ding ding! We have a winner.

 

Thanks for your confirmation to the masses

 

Thank you and Marco!!!!

 

well my understanding with any of the tuners is that when you load the stock info back the info starts at the last time it was stock so say you flashed it 20 days ago and now you're going back to stock. the computer will only show info from 20 days ago and on.

and I agree with logan. anything done to the computer is traceable. anything. it all depends on how hard you want to look. the dealers dont have the computer knowledge to dig into the computer like DC could.

 

There's no way that manufacturers are equipping vehicles with enough memory to record EVERYTHING from EVERY computerized censor in a vehicle for the life of the vehicle I don't care how hard they dig for it. If I drive my truck for 10 years, you honestly think every time the seat belt isn't worn in the driver seat or every time I speed is going to be recorded and retained for the life of the vehicle? Even if all of that is recorded continuously, at some point, old data would have to be recorded over.

When the costs are weighed against the benefits of all that record keeping, it just wouldn't be worth it to the manufacturers or the buyers...

 

I'm telling y'all... There are black boxes. They recourd only a short history. If you toast an engine it takes a snap-shot of what was going on when it happened. Then you a screwed... Which it does not matter because when they pull the engine down it will be obvious that you had it tuned up. I am sure that is what happened in the little story of logans friend or whatever crashing... They looked up what happend at the time of the crash... The state police around here use the same thing in there investigations.

Here you go guys.... Some good reading on it. Says 20 sec of record time
Psst, Your Car is Watching You - TIME

USATODAY.com - 30 million cars now record drivers' behavior

 

exactly. the box is a computer and if you know how a computer works then everything stays in the computer until it is overwritten by something else. lets say a code. If you got a code and drove 20 minutes with the code it would still be there until so many key cycles, but would still show up in history. same theory.

now smarty may be a little harder but someone could find it. a module is still less detectable

 

Yes... But the boxes overwrite themselvs about every 20 seconds
