• We test and dyno tune on our own cars to make sure what you get is safe, reliable, and gives you the results you want!

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.
• 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.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

Options:

• You can select to get one of our Stages ECU Tunes. The Stage 2 is usually for those looking to maximize the performance of their vehicle. Though not required unless stated, this is usually for those running a performance exhaust and at least 91-93 octane fuel. Switching between stages can only be done if OBDII flashing is available.
• For this ECU Flash, we also offer the following features that are optional and can be selected:
• Pops and Bang Burble Tune
• Speed Limiter Raised - VMax
• Some features not listed can be requested during the File Upload process

For reference this ECU is a Bosch MED17.7.3.1.
