Way too much misinformation and stupidity in the responses that could've been cleared up with a simple search, also why would you even get a tune without doing this research first?

I did get an illegal tint ticket once

This is from documentation the great tuning god @
steve99 has found:
Guaranteed flash cycles 1000 , typical cycles before failure 10,000
Programming/erasing control program included as firmware of the ECU itself
Although if you go an flash the car on a low battery your flipping the coin on whether or not you'll brick the ecu, and I've heard peoples OBD2 socket pins go bad after repeatedly unnecessarily yanking the cable.
Also as a Electrical Engineer/Computer Engineering Major, 2 MB of Tables and other data probably isn't going to fragment especially the way it's stored on the ecu, on a solid state storage solution.

You're best bet is to flash to stock for dealer services, even though our roms aren't like ecuteks where it's easily visible because the rom locks the ecu, if they decide to say do a TSB which involves the ECU reflash there's no way the OFT will work again. Also I've gone into at least 3 dealer services so far, 1 with a TCM reflash without flashing back to stock with no issues. Techstream cannot detect the tune because it's basically an edited stock rom, you'd need to send the ecu away for anyone to find anything.
This is from @
steve99 s post:
Depends on flash device.
Devices such as Open flash Tablet or Tactrix/Ecuflash do not encrypt or lock the tuned ROM. When you flash back a stock ROM with these devices it is 100% stock.
This means the dealer can connect to car with TechStream (dealer software) and interact with the ECU in the normal manner. even if they pulled your ROM its 100% stock.
Tuning Devices such as EcuTek and BRZEdit have the ability to lock and encrypt the ROM in the ECU and Dealers may not be able to connect/re-flash to interact with the car's ECU in some cases if these locked or encrypted (seed key changed) ROM's are left in the car. If you have the required cables and licenses you can flash a "stock" ROM back to your car but it contains license info which if they were really looking they could detect.
OBD code readers or clearing of OBD diagnostic/CEL codes should still work. The ROM encryption/locking generally only effects the ability to read or write/re-flash the tuned ROM.
Dealers use Techstream software to connect to ECU it can read the ROM calibration ID and various engine parameters but no one has found a "flash Counter" yet.
It possible if they sent your ECU away for analysis or they brought in some super guru in they could detect something but this is unlikely at a standard service.

Covered maintenance is NOT the same as warranty service it is allowed and you won't have anything to worry about. Unless your dealer is extremely mod unfriendly, I even got my dealer to align my win jets correctly for free......

It's up to you if you have UELs the Stage 2 tune might be the only way you'll pass. Just tell your service advisor to speak to you before doing any ecu or invasive work if it's necessary like a TSB, and say you'll come in an other time to do it. But honestly Openflash Tablet is so user friendly and only takes like 5-6 minutes to flash back to stock so why wouldn't you.
