Removal of Chip and programing ECU with latest Bostig tune
The SCT X4 was received about one week after I purchased it. It only took approximately one hour to register, down load and update the X4 to the latest operating software and firmware. This operating software is required to be updated first prior to uploading the latest Bostig tune into the X4. Loading the Bostig tune into the X4 was done very easily using the SCT X4 software on my Dell laptop with Windows 8.1. Programming the ECU with the latest Bostig tune took approximately five minutes after connecting the X4 to the OBD port and following the instructions off the X4 screen.
