dealer guy told me this a long time ago. "you can mod these cars up pretty good, but i wouldnt do it because it will void your warranty." then he says "even if you take the parts off the ECU knows that a part was changed and then put back on so its always on record, so you cant cheat the system."

can they really do that??

Is his implication that the ECU keeps a permanent record of changes in it's sensor readings (that's the only way it could tell if an engine component has changed)?

Doubtful.

btw, ray, your wrx drawing is fantastic. i bet you could have drown an awsome naked picture of Rose in the titanic movie.
I wouldn't mind having the opportunity. (at least, back then; didn't the girl that played "Rose" in that movie get kinda fat later?)
Thanks for the compliment.

I doubt this is the case, but a few other manufacters claim that they can do this. A easy to fix to this would be to disconnect the battery. The computer isnt crap without some kind of back up power to it. I'm sure if you did the SHIV test it would toss all the sensors into a stock mode right? I think he's full of bs and if this is the case who come no one that has taking a stage 4 back to stock has had any problems selling it at a dealer?

Well, in theory, if the data was stored to flash memory, disconnecting the battery wouldn't get rid of it. I read somewhere that some modern ECU's are recording the last few seconds of data to some kind of medium, for use in accident investigation. It wouldn't make sense for that to require battery power, since the power system of the vehicle may not survive a rough accident.

Well the more I think about this the dealer (I figure it's safe to say most are stupid) was probaly talking about any mods tossing a CEL and then the CEL being stored in the computer. You could tell if you it a Cat code that most likely the catback exhuast was put on. I'm sure Subie's computer is advanced as ford and everyone elses (if not more advanced) so they can probaly narrow it down to what cat....meaning in theory unless you clear code they'll know you have a UP/DP. Oh well just guessing again

As for Rays post I can see your arguement, I just havent seen or heard of any of these types of investigations. All the accident reports i see (I see more then the average) still go off of skid marks and impact points. I have yet to read a report where anyone has pulled the RPM's, Gear, Speed, or any thing else off a ECU that would determine speed. But then again I am by no means a Crash detective.

Oh believe me, I claim zero expertise on this subject. I'm just repeating something I heard about for the sake of conversation.
I'm quite confident that you're right about the dealer guy; he was probably talking about the CEL codes. But as we all know here, you can clear those out easily enough. :)

On a more educated note, all GM MY06 and up are going to have whats considered a "blackbox" these would record all vehicle data, speed, direction, all engine parameters, store data. If you changed a part and modded your car someone would have to look at the data and infer from that what you did. but think about it like this, From a modding point of view, if people are really going to sneak some sh*t by the dealer, it wont be too long before someone can hack a black box and get at the info, etc, before standalones thats what people had to do.

Right, this is what I was referring to in my earlier post about this.

I believe the ECU does record some data points, but for how long I am unsure. I know this only b/c it does monitor your Tachometer that way the mechanic can tell if you are driving your car really hard.

But it recording all sensor points for a long time? Meh, doubtful.

Certainly possible since, all the cars with the "black box" are Onstar capable and when the storage space gets filled, like say in a couple months, it uploads the information and then starts all over again. so you could potentially have your entire driving history on someone's computer, well not potentially, you will if you buy GM

For myself, if I know that this is the case with a particular vehicle, it will be enough to deter me from purchasing that vehicle. Big Brother indeed.

I seriously doubt that we're there yet, though.
