How to Flash Your ECU?

• Use the Alientech Powergate 3+ handheld device. This device is a touchscreen module that lets you store your original and tuned files to easily flash between them. See Instructions Here.
• Use the DimSport handheld device. This REQUIRES a Windows PC. This is an OBDII tool to read and write the ECU. See Instructions Here.
• Bring your vehicle to our facility where we can use our Master Tool to flash your vehicle.
• 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 ship it back to you for re-installation. We do not solder or modify the ECU board at all. All ECU tuning is done via bungy probes that have a needle tip to provide an electrical connection.

For reference, this ECU is a Denso P5.0SC.
