Anyone with tunes got hassled on your warranty?

Wait... I know the 135i's can now trace that you have loaded tunes even if you do return the tune to stock. Does the Accesport for the Z now trace this also?

They probably loaded the stock tune that was on the tuning device instead of uninstalling the tune they added. I cant see how uninstalling the new tune would be traceable, basically youre eliminating all traces of what was uploaded.

unless it, the ECU, keeps track of the dates it was changed. Kinda like a computer that gets updates every so often, they are tracked by dates. Im sure if they wanted to know they could make it so. Look at Toyota and their black box, they wont let anyone look at it cuz its tracking all kinds of ****.

And like a computer Im sure even though you wrote over one with another, its still traceable on the memory device.

But that shouldnt stop any warrenty work unless they can prove the tune was the cause, they shouldnt be reading the ECU just for the heck of it.

No... the 135i guys were unloading the 'custom' tune and reloading the stock one and STILL it was traced.

I, like you both, do not think it will be that much of an issue as they will not check the CPU everytime you go in....

Thats because the computer stores the codes.. I work at a vw dealership and its the same thing with the tunes on the 2.0t motors. you can just read the boost levels on the ecu and know its chipped.. and if the chip was set back to stock normally the ecu stores overboost codes and you can tell that way.. nothing is fool proof even if cobb or whatever company tells you it is.

That's what I'm worried about.
