Porsche 958 Cayenne S ECU Tune



*** Unlock the hidden power gains detained in your Porsche’s ECU with a Hydra Motor Works ECU Tune. ***

Maximize your Cayenne’s horsepower, torque and drivability with a Hydra Motor Works ECU Tune. Our tune is designed to take your 958 Cayenne’s performance to the next level while maintaining OEM reliability. This vehicle utilizes a handheld tuning device which connects to your OBD-II port on your vehicle to make the tuning process as user-friendly as possible.

How it works:

The handheld will read your OEM file through a connection via the OBD-II port.

Load MyGenius software on your computer and connect handheld device.

Load OEM file onto your computer and email file along with our ECU Tune guide to Hydra Motor Works.

Once the file is received, we will rewrite you a custom tuned file within 24-48 hours.

The tuned file will be sent back to you. You then will be able to upload it onto your handheld device, then onto the vehicle

Flash back to the OEM file at your convenience directly from you handheld device!


Once connected, the handheld unit is married to your vehicle. This means you will only be allowed to use it on this vehicle only.

Please make sure you have access to a Windows / PC computer to upload and exchange file information.
Please make sure you review, complete and email in our ECU Tuning Guide. This guide is to help us provide you with the most optimized tune for your vehicle’s specifications and modifications.

Power gains may vary depending on other modifications done to the vehicle.
