I have a chipped t-box and i want to get a stock chip for warrenty work, but all i can seem to find is M-boxes. if i buy a stock M-box and switch the case's, would the dealer be able to tell that i don't have my original chip in there??

as they hook up a scan tool they'll know it's an M-box.

so basically i have to buy another T-box??

If you want to increase your chances of getting away with fraud then yes, you need a T box

use that ecu for warrenty work, and i won't have to switch the chip from my original ecu to the new one and the dealer would not know the difference? correct?

Thanks

then you'd have to have the same ECU that came with your car in there for warranty work or a stock ECU with the same build date.

(FWIW, if the dealer really wants to F with you for a major warranty related issue, they will find out if it's not the original ECU box.)

Be prepared to pay for work related to the motor/drivetrain if you're chipped.

I believe there is a month/year "build date" on the ECU. If the ECU build date is after the car build date, your are busted.

Other tip offs....
worn screw heads for the ecu cover.
scratches on the surface of the ECU caused by the retaining clip
worn screw on the ecu itself (opening the ECU box).
Some people have pictures of where the dealership used black paint on the ECU housing to see if it was opened.
There is the obvious power loss code (if you were too foolish to clear it)
there is the lack of EPA resets. The ECU needs several miles (some say 50) to fill all the data cells.

An excuse to use if you are asked about the screw heads/scratches:
I had to park my car on the street and I was concerned about theft, so I pulled the ECU before leaving town for a while and kept it inside.


Good luck
