Supported ECU

76F0038/39/40/70/85, MPC565/SH72512/SH72544 CAN-bus [VR/WR/CK]
76F0038/39/40/50/70/85, 70F4019 GearBox CAN- bus [VR/WR/CK]
76F0038/39/40/50/70/85 HV Control CAN-bus [VR/WR/CK]
76F0004/23/38/39/40/70/85, MPC565 K-Line [VR/WR/CK]

It consists of three modules that differ by the type of communication with the blocks:

76F0038/39/40/70/85, MPC565, SH72512 CAN-bus [WR/CK]
76F0004/23/38/39/40, MPC565 K-Line [WR/CK]
76F0004/23/38/39/40 K-Line JDM [WR/CK]

That means one module is for CAN, the second is for K-Line, and the third is for vehicles with K-Line specific to the Japanese market. The processor type is provided for general information, but the program will automatically determine everything it needs.

These processors are installed in control units produced by Denso, Fujitsu Ten, and Hitachi/Delphi.

Firmware version for OpenPort 2.0 should be no lower than 4340, otherwise, it won’t work with CAN.

The new LC200, LX570/450d models are supported starting from PCMflash version 1.1.64.

Procedure:

Perform identification until it’s successful.
Find a file with an exact matching software version and start the flashing process.

For vehicles with K-Line, it’s crucial to follow the program’s instructions carefully. Turn off the ignition for at least 15 seconds when requested and turn it back on when prompted. It may also be necessary to remove the key from the ignition.

A very important note for those wishing to use OBD:

ATTENTION:

In case of a failure, you will need a programmer (for example, the Autokey Toyota Lexus Flasher). If you don’t have access to one, it’s better not to proceed. For K-Line, you can likely avoid using a programmer. Try turning the ignition off and on again, attempt to restart the flashing process, or, if that doesn’t work, enable the “recovery mode” in the settings and try again.
The likelihood of failure exists and is not zero. The most common problems are:
Poor contact in the OBD socket, which can happen even on a new car (!)
Interference from additional equipment, such as aftermarket alarm systems
There is no reading function, and I do not provide a stock file set. Finding a suitable file is the responsibility of the tuner.
When using the OpenPort 2 adapter, the firmware version requirements are the same as for Valeo 42. Mongoose/Pro JLR, Chipsoft, and Ford/Mazda VCM 2 adapters have also been tested and confirmed.

The specifics of Toyota’s programming protocol are such that when receiving an incomplete or corrupted message, the ECU often enters a “halt” mode, and repeated flashing is usually impossible, even if the ignition remains on. It’s a bit easier when dealing with K-Line.

In version 1.1.71, a display feature for updated calibrations has been added, allowing you to flash these directly into the ECU without requiring a prior update via CUW. It looks something like this:

Calibration: 34224200

Calibration file: 89663-42242

Update: 89663-42E70 89663-42246

Hardware number: ALA30 2ADFHV

Catalog number: 89661-42C00

CVN number: 4B7DA8EB

This simplifies the process and makes flashing more efficient by skipping the CUW update step.

As a result, you can immediately flash one of the three calibrations into this ECU: 89663-42242, 89663-42246, or 89663-42E70.

After flashing 89663-42246, it changed to the following:

Calibration: 34224600

Calibration file: 89663-42246

Update: 89663-42E70
