The "Superchips Spark software checks for updates and appears to send your vehicle files for analysis, then says that you have to wait 2 weeks and a custom file will be created for you. I was disappointed so I called to ensure this was necessary prior to use & was told yes. After the two weeks, called again and no record of me was in the system. After much troubleshooting, remove fuses etc. it would not update the vehicle. Note that this device Requires 12.8v with vehicle off.
