You must review our MyGenius ECU Tuning Guide and email the ECU Tuning Information form to us. We utilize this form to ensure we meet your needs and consider your modifications to deliver the best possible results.

You must have access to a PC / Windows computer (Mac OS not supported) to upload your factory file information to us via email and in turn apply our ECU Tune to your Handheld device.

Upon sending us your vehicle information, our tuner will email you a custom ECU Tune(s) within 1-2 business days.

The Handheld device "marries" with your vehicle and can only be used on one vehicle.

Special requests and tune file upgrades may be subject to additional fees.

If you prefer a traditional bench flash (mailing in your ECU) over a handheld device, or you are unable to use the Handheld device please contact us.
