This is a complete replacement ECM for the factory computer in a 2019 Corvette ZR1. These are brand new from GM and unlocked from HP Tuners. Included in this price are five GM rivets necessary for reattaching the carbon fiber side skirt (five is the recommended number to remove to be able to manipulate the side skirt).
The E99 requires ten credits to edit which are available here.
You must provide your VIN upon ordering.
