How to Flash Your ECU?

• Use the DimSport MyGenius handheld device. This unit lets you store your original and tuned files to easily flash between them via the OBDII port. A PC is required for the initial loading of files to the unit.
• We can bench flash the ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us. Once we receive the ECU, we will prepare the tune file and then send it back to you for reinstallation.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

For reference, this ECU is a Bosch MG1CS201.
