Direct connection to the ECU connector is required for operation!

Supported ECU

• ZF TC1782/TC275/TC277 TCU (FLASH) [ RD/WR/CK ]
  
• ZF TC1782/TC275/TC277 TCU (EEPROM) [ RD/WR ]

In version 1.3.6, a new module 96 “ZF TC1782/TC275/TC277 TCU Bootloader” was added, designed to work in service mode with ZF transmission ECUs such as ZF 8HP Gen 3, ZF 9HP, ZF 8DT (PDK2-TC400), MB 8G (VGS3-FDCT), VAZ AMT, Renault JHQ, which use TC1782, TC275, and TC277 microcontrollers. The module supports reading and writing of the built-in FLASH and EEPROM memory when connected directly to the ECU port (no disassembly required), as well as checksum verification and correction.

General Information: The supported ECUs are usually manufactured by ZF, with part numbers ES10-xxxx, ES11-xxxx. However, for BMW, Bosch mechatronics are mostly used but with ZF software. All of them are based on Tricore microcontrollers:

1. TC1782N – a reduced version with lower frequency and a smaller guaranteed working flash capacity of 2.0MB; these are the earliest ECUs on this platform (AMT/9HP48).
2. TC1782F – operates at a higher frequency and uses a 2.5MB flash, found in later 9HP48 ECUs.
3. TC275T – used in current ZF ECUs (8HP Gen 3, 8DT, 9HP50, 8G).
4. TC277T – used in current Bosch ECUs (BMW 8HP Gen 3).

List of tested ECUs (these can also be selected in the ECU type for checksum verification and recalculation):

BMW 8HP Gen 3 (TC275/TC277)

Chrysler/Jeep 9HP (TC1782)

JLR 8HP Gen 3 (TC275)/9HP (TC1782/TC275)

MB 8G/VGS3-FDCT (TC275)

Porsche 8DT/PDK2-TC400 (TC275)

VAZ/Renault AMT/JHQ (TC1782)

Capabilities:

ZF TC1782/TC275/TC277 TCU (FLASH) [RD/WR/CK]

ZF TC1782/TC275/TC277 TCU (EEPROM) [RD/WR]

Tuning: Simply read and write without adjusting any settings. The optimized writing process is very fast (only the differing sectors are written), similar to modules 71 and 92.

Cloning:

1. For Jaguar/Land Rover transmissions (ZF 8HP Gen 3, 9HP48/9HP50), it’s sufficient to rewrite the FLASH and EEPROM, even without skipping the service areas.
2. Also works with VAZ/Renault ATM/JHQ.
3. Not tested with others. Recommendations for those who want to try: a) Start by just rewriting the FLASH and EEPROM. If the vehicle doesn’t start or enters a failsafe mode, then b) disable skipping the service areas when writing the FLASH. If it still doesn’t work or you’re trying to switch between brands (e.g., JLR to FCA), then c) select “Other” ECU type and disable skipping the service areas, but note that failure during the bootloader rewrite can result in a bricked ECU. For blocks on TC1782F, it is likely possible to fully “flash” them with TC1782N software, and it will probably work (this is true on the bench, but whether the car will run is unknown, as there could be hardware differences on the board). In other cases, the processors must at least match. So, proceed at your own risk.

Service areas: Besides the three bootloaders, they apparently also contain calibration data for the board. Therefore, rewriting these areas should be done only with a full understanding of what you are doing. This is an “advanced” feature for specialists.

Connections: As usual in boot modes, automatic power management is required. There are no special requirements for the adapter, but it must be fully compatible with J2534. For BMW, it may be necessary to connect through an intermediate connector (see photos in the connection guide), and note that there is no ground in this connector; it must be attached to the vehicle chassis.
