We have several Frequently Asked Questions answered here, take a look if you have any questions.

How do I get my ECU back to 100% Stock?

Before going back to stock, contact UpRev Support. We now need 2 screenshots to return your license. These screenshots prove you had the license and removed it that way we can return it. They need to be of Rom Editor open in full screen mode, the time and date stamp in the bottom right of the computer needs to be visible, and you need to use either the 'Screen Capture' button in ROM Editor, or the Windows Snip-It Tool to take the screenshot - NOT a cell phone pic. The first screenshot will be of the ROM Editor showing that the car is an UpRev Flashed ECU and will need to show the ECU part number, the cable serial number, and the date/time in the bottom right corner. You can then use the UpRev cable to flash the "Back to Stock" ROM for your ECU. After doing so, take a second screenshot to show the car is stock with the ECU part number showing, the cable serial number showing, and the date/time in the bottom right corner. You will then create a license report by going into ROM Editor, clicking 'Cable Management', and then clicking 'License Report'. Save the file to an easily accessible location, and then send an email to license@uprev.com with subject line "Back to Stock Request". Attach to that email the 2 screenshots and the license report, and we will get back with you promptly. *** YOU HAVE 10 BUSINESS DAYS TO EMAIL A BACK TO STOCK REQUEST TO license@uprev.com AND RECEIVE BACK YOUR LICENSE. ANY REQUESTS PAST 10 BUSINESS DAYS FROM GOING BACK TO STOCK WILL NOT BE GRANTED. PLEASE UPLOAD YOUR RETURNED LICENSE IMMEDIATELY UPON RECEIVING IT. LICENSE REPORTS CAN BECOME OUTDATED IF NOT USED. ***
