This is my 2nd Tuned Cruze and my dealer never said anything about it.I purchased the BNR tune for my Cruze Eco and have uploaded it into the car. However, does anyone know how to return the car to its original stock state so when I take the car to the dealer they won't see that it's tuned?
are these cars like android phones where they keep a flash count so they can see how many times it was flashed??Also returning the vehicle to stock won't hide the fact it was tuned. It just hides the tune itself. Which is good, because GM can't void your warranty based solely on "Because it was tuned".
They are, but some tuners are able to bypass the flash counter.are these cars like android phones where they keep a flash count so they can see how many times it was flashed??
and a tune wont void your warranty??
Sort of, I mean dealers will be stubborn. Some of them don't care. But if you kick up enough dirt, you will get your warranty work.are these cars like android phones where they keep a flash count so they can see how many times it was flashed??

Yeah. It's an easy simple math problem. Or you can brute force it pretty quickly. But its illegal (debatebly, but the chance of the tuner winning is really low). There has never been an actual legal case of it, but there have been love letters.They are, but some tuners are able to bypass the flash counter.
I just purchased the BNR Tune. I sent them two .ctz files, one of engine and one for transmission. They sent me back four files, a pair stock files (engine and transmission) with a .coz and a pair of BNR tune files, same engine and transmission .coz, so that does away with need for conversion above.Alright I figured it out! This may not be the only or best way to get your car tuned back to stock via EFI Live, but it works. I knew I had my stock tune the entire time in case people thought I misplaced or deleted it. The issue was being able to actually PROGRAM the stock tune back onto the car because it wasn't the same file type as the BNR tune that Jerry sent me. Here are the steps in case anyone else needs to revert back to stock:
1. On your computer, locate the E78_0001 read file that you extracted from your car initially. We are going to convert this file to the same file type that the BNR TUNE file is.
2. On your computer, open EFILive Scan and Tune (not EFILive Explorer).
3. On the left pane, click F8: Tools (it may be a different "F" number depending on what version of the program you have).
4. In the new window that appears, click F7: Copy.
5. In the "folder" field navigate to the folder in which you have your stock read file saved.
6. Uncheck the "test only" check box, and then click copy.
7. This process converts your .ctz read file into a .coz tune file, the same file type that the BNR TUNE file is. It also leaves your original READ file intact. I would suggest naming the new file "STOCK TUNE" or something like that so it's easily recognizable.
8. Once the copy is complete, copy the newly created .coz file into the Tune folder on your Autocal device, just as you had before to put the BNR TUNE on your car.
9. Upload the "STOCK TUNE" file onto your car using the same process that you use to put the BNR TUNE on your car.
10. That's it!
Hopefully someone finds this useful. Let me know if you have any questions, comments, or concerns.

Granted the entire tuning industry is a giant legal crap hole waiting to explode, but its best to keep the grey areas to a minimum if they are not needed.
