Frequently Asked Questions

Does the FEMTO unlock survive dealer software updates?

Yes. The unlock is permanent and stays in place even after dealer updates.

My GR Supra was built before 06/2020. Which service do I need?

Earlier Supras use a different ECU unlock. See our GR Supra B58 Bench Unlock Service (Pre-06/2020). If you're unsure, email your VIN to sales@sequentialracing.com.au and we'll confirm.

Is a tuning licence included?

No. MHD, Bootmod3 or MG Flasher licences are purchased separately. Bootmod3 users must activate their licence before sending the ECU.
