How does the Shark Injector work exactly?
The Shark Injectors software replaces the stock BMW software but not all of BMWs programming is changed. When plugged in and the button is pressed, the Injector reads the stock software and stores it for later retrieval if necessary. It also records the VIN number and other required information. Then it programs the DME with its new Shark Injector files. After programming, the Shark Injector verifies that the transfer of data was completed.
