🔥 BM3 CustomROM & MHD+ Now Available for BMW & Supra!

🚗 BMW & Toyota Supra ECU Tuning Now Possible Post-06/2020 with Femto DME Unlock

If you own a BMW or Toyota Supra manufactured after June 2020, you’ve likely encountered the locked DME (ECU) issue. These vehicles are equipped with a new secure bootloader that prevents tuning via OBD flash tools like Bootmod3 (BM3), MHD Tuning, and MG Flasher.

✅ The solution? FEMTO DME Unlock Service

The Femto Unlock is the only global unlock solution that enables full ECU access for tuning on all post-06/2020 BMWs and Supras. Once unlocked, your car is fully compatible with:

• 🔧 Bootmod3 CustomROM (bootmod3.com)

• 🔧 MHD+ Performance Tuning (mhdtuning.com)

• 🔧 MG Flasher

Whether you want Stage 1, Stage 2, flex-fuel support, or custom maps, a Femto unlock is required before any ECU flashing on post-June 2020 vehicles.

1. Place your order on our site.

2. We send you a prepaid shipping label.
