Pre-Flashed BOSCH 8HP TCU for MaxxECU Mtune – 8HP45 / 8HP70 / 8HP90

This listing includes genuine BOSCH 8HP transmission control units (TCUs), pre-flashed with MaxxECU's 8HP firmware v004. Each unit is used, tested, and ready for plug-and-play operation with MaxxECU's Mtune software.

Why You Might Need This?

Incompatible OEM TCU:
Not all 8HP TCUs are supported by MaxxECU. If your transmission came with a variant that cannot be flashed (non-supported chip type), MaxxECU cannot control it. We provide a solution by supplying a compatible, pre-flashed unit.

Bricked TCU Recovery:
If a previous flashing attempt failed and your original TCU is now bricked or unresponsive, our units offer a drop-in replacement.

Important Notes:

This is not a flashing or exchange service – you are purchasing a standalone, pre-flashed TCU.
These TCUs are exclusively compatible with MaxxECU and Mtune software. They will not work with OEM or other third-party ECUs.

Once you place your order, we’ll dispatch a ready-to-run MaxxECU-compatible TCU for your 8HP gearbox.
