ECUMaster Announces ZF 8HP Control Coming Soon
ZF 8HP
Connect EMU PRO or EMU BLACK to a ZF 8HP transmission’s original TCU over a single CAN bus — no additional transmission controller required.
ZF 8HP integration is coming soon! ECUMaster is opening a closed Beta for experienced users with an EMU Black or EMU PRO and a ZF-manufactured 8HP transmission to help validate additional applications before release.
Release dates:
Late November 2026 – Closed Beta testing is expected to begin (Apply for the Closed Beta).
Full release – TBD
Planned Features:
- EMU PRO and EMU BLACK communicate with the factory 8HP TCU over a single CAN bus – no additional transmission controller required for operation
- Supports compatible first- and second-generation ZF-manufactured 8HP transmissions
- Unlock and flash the TCU yourself using ECUMaster USB-to-CAN and the free ECUMaster 8HP Toolkit app
- Original BMW F-Series shifter support for familiar OEM-style operation
- Shifter emulation via EMU – paddles, buttons or a sequential lever
- Custom shift points – tailor shift behavior to street, track or drift
- Virtual Clutch for easy drift initiation
- Transbrake
Supported transmissions
The following ZF-manufactured BMW transmissions are currently known to work:

Frequently Asked Questions
Which 8HP transmissions are supported, and when will additional models be available?
The BMW 8HP50 (Gen 2) and BMW 8HP70 (Gen 1) are currently known to work.
Additional ZF-manufactured 8HP transmissions will be validated through the closed Beta. There is no fixed schedule for a particular transmission: testing depends on a suitable customer with an EMU Black or EMU PRO and that transmission volunteering. We plan to support all popular variants as suitable customers volunteer and validation is completed.
Will this support licensed 8HP variants or other transmissions, such as the 6HP, 6R80 or DCT?
No. This program is limited to ZF-manufactured 8HP transmissions. Licensed 8HP variants manufactured by other companies are not supported. The 6HP, 6R80, DCT and other non-8HP transmissions are not supported and are not currently in the development pipeline.
What features and tuning options, including selectable modes or a transbrake, will be available?
We will share more details as soon as they are available.
Can one EMU control the engine and the 8HP transmission?
Yes. An EMU Black or EMU PRO can control the engine and communicate over CAN with the original factory TCU inside the transmission’s mechatronics unit. The EMU influences the factory TCU; it does not directly control the transmission.
There is no need to remove or physically modify the factory TCU. However, if the original TCU was removed or modified to accommodate another external controller, it must be replaced with an original factory TCU before using the ECUMaster solution. The factory TCU must still be unlocked and flashed with ECUMaster-compatible firmware.
How much does 8HP support cost, and is additional hardware required?
8HP support will be included at no additional cost with EMU Black and EMU PRO. Existing owners can use the feature without purchasing dedicated transmission-control hardware.
An ECUMaster USB to CAN module is required to initialize the gearbox. You can borrow one or purchase one from ECUMaster USA for $169.
How can I join the closed Beta?
If you have an EMU Black or EMU PRO and a ZF-manufactured 8HP transmission, apply for the Closed Beta here. Testing is expected to begin in late November 2026.
