im planning to purchase the cobb chip questions i have are.... if i cobb the ecu and say i need to take the car to the dealership can i reflash my ecu back for them not to find out that i messed with it before.... and is cobb a plug and play????

 

Yes, plug and play.

 

yes you can replug the stock map back in so they will never know you changed the map settings on the ecu

 

I've heard, on the STIs, that if the dealers really wanted to, they can still see that the ECU's been reflashed before even after you put the stock map back on. Don't know if this is true.....

That is true with the ecu on the new sti's my brother has one and that is what he was told. When the ecu is flashed its stock ecu code is changed. When you reset the stock map it changes the code again. Subaru has the stock ecu codes on file and can check to reference to make sure its the same code. If it shows different then they can tell. That's what I was told. Don't know if this is the case for our cars tho.

 

Hm, someone should find out, or call Cobb.

PS. 08 STI with Cobb stage 1 or Parent stage 1 can spank our Gs all day every day :/

u got pm!!!

 

Ya but stock I dunno. My brothers doesn't seem that much faster than his 02 wrx lol.

The G is way classier, sexier, and more comfortable so I don't really care.

 

i just called up cobb and found out they said IF THEY REALLLLLY get into it they can see that the ecu got re-flashed but he said thats its every rare they ever go and check for that and very little people came back with saying that they got cought

 

Every car manufacturer can tell if an ECU has been altered, even these plug n play ones that can reprogram back to stock configuration. However, it's expensive and time consuming and the only way it would be feasible for them to do that is if they needed to. Such as when there is an issue resulting in a huge lawsuit where they needed to prove that it had been altered, like a fatality accident being blamed on a car defect or something of that nature. Even then there is a way to "wipe" it but I won't discuss it here.

 

wanna let me in on the secret....

 

An ECM has an ECM Code which specifies the subfiles or core files within which produce the advertised hp and torque. The ECM Image has a "Calibration Date" field which tells the date the cal (ECM Code) was loaded. So, if you bought your car in 2008 and the "Cal Date" shows March of 2009 then its a dead give away. It should take 5 minutes to hook up a datalink adapter, connect to the ECM, take an ECM image, save and open the image, the search for "Cal Date". This isn't a hard or time consuming process...AT ALL.. if you know what your doing that is

 

All that will show is that something was done to it an when, correct? The method I'm referring to involves proprietary software to specifically read the very detailed "Black Box" information that every ECM records at all times in a variety of fields. I don't think were talking about the same thing, are we?

 

Yeah your right. Infiniti has the ability to take an image very easily. It takes a datalink adapter (which is the translator) and software specific to the ECM its connecting to. It would be difficult for us to take an image (but not impossible since this is how aftermarket tuner groups "crack" an ECM) and read it, but for the manufacturer its all in a days work. An ECM is basically a slower smaller pc. It has dual RAM, EEPROM, Procesor, Preprocessor, memory, etc. So if you have the means to "log on" its easily accesible and readable. Its the same as loggong on to your pc, opening an excel file and reading the stored data.

 

ecu=....? Also, anyone got a link so I can see what this cobb thing is?
Thanks
