Software Use and Dongle Activation

In order to use the software you are to install the dongle driver. You can download detailed instructions here.

You are to connect the USB dongle to your PC only AFTER you install the Guardant drivers. If the dongle is connected before the driver installation and Windows Hardware Installation Wizard has started, you are to disconnect the dongle from the PC and cancel the Wizard.



  1. Install Guardant driver selecting the appropriate one for your operational system.
  2. Restart your PC if needed.
  3. Connect the dongle to a USB port.

You are to install the drivers on all PCs you are planning to work on. However, the dongle is activated (if needed) only once and on one of those PCs. After the activation the dongle stores the necessary parameters. Activation is required for dongles received by mail and is described in detail above.

As a rule the dongle firmware will be updated together with the software releases. In this case you will get a warning: 

All updates are automatic and do not require any specific actions. It is enough to confirm your intentions to use a new version. Update takes just a few seconds. If you buy other modules in future, you can activate them using “Settings” button, see below.

Openport 2.0 Firmware  Version Rollback

NB!: the developer recommends to roll back the Openport 2.0 firmware version for correct functioning of some modules (Nissan/Infiniti, Honda, etc.) or to use some other J2534 device. Please note that this is not recommended by the adapter manufacturer and can lead to the breakdown which would not be considered a warranty event. If need be, you do this at your own risk, and in case of any problems you can contact the PCMFlash developer, but remember that only you are fully responsible for your actions. 

Technical Support, Updates. Software Manual.

There is no official help file at the moment. All technical support is provided via email, and on the forum. The software updates can be downloaded from the appropriate topic (the access is granted by the developer after the registration, filling all the profile fields is required). The unofficial version of the help file from Pashkovsky65 is avalable for everyone (it is recommended to buy the full version). 

Infeneon TriCore Support

The module is intended for professional use only. You are to find the connection methods to the ECU and pinouts yourself. The GPT adapter is required to work with GPT ECUs. You can find some instructions from the developer and users here.

PCMFlash is an integrated software solution intended for reprogramming ECUs and TCUs of Volkswagen, Skoda, Ford, Mazda, Mitsubishi, Nissan/Infiniti, Subaru, Honda/Acura, Hyundai/Kia, Renault, Toyota/Lexus and other vehicles. There are universal modules Denso SH705x Bootloader and BSL TriCore. It supports work via ADS adapter (version 1, not for all ECUs) as well as via any J2534-compatible adapter if there are appropriate drivers and libraries. The tool has been tested with OpenPort 2.0, Mongoose JLR, MongoosePro JLR, Teradyne GNA600 (VCM 1), Mazda VCM 2. The software is marketed on a module basis and has simple and clear interface. The Guardant dongle is used for the protection from unauthorized access.

It supports flashing both backup (vbf) and binary (bin) files. When flashing binary files checksum verification and correction is available for most of the modules. Conversion from VBF/GDS into BIN is supported if the ECU doesn't support reading. Most modules support checksum verification and correction as well as VID transfer (if needed) while flashing binary files.
