You still need to know the various CAN IDs, data formats, how to clear error codes, etc. All that required detail is only contained in the MUT software, as far as I know.datom said:What about leaving the MUT software alone and just "faking" a VCI?
Vehicle Communications Interface. That's the hand-held part; the MUT looks like it's a smallish ruggedized laptop. There are two models; the one with the small display and three buttons, and the VCI-Lite without a display at all.JoeS said:VCI = Virtual Circuit Identifier?
Good point, but in the end you’re still going to be ‘limited’ to what a MUT3 can do, i.e the “wish list” @hjdlsnbc compiled will remain just that…I believe a simple can device can do the same thing as the MUT3. You would need to create your own GUI or just report results on a simple terminal program like Tera Term.
The MUT3 can program anything in the car. You still need the file.Good point, but in the end you’re still going to be ‘limited’ to what a MUT3 can do, i.e the “wish list” @hjdlsnbc compiled will remain just that…
What file did you talk about? The one you have to calculate the new checksum after you modified things inside it before writing it into the memory of the car?the file
I am spe4aking of a firmware file to reprogram a device like the BMU or EV-ECU for instance when the tech has to install a new one. I believe the files are on their web site but you have to buy a subscription.What file did you talk about?

Yes, as I understood kolyandex.... he downloads the file from your BMU and modifies it. Then he re-flashes the BMU with the changes. I don't know how you read the file because that ability is grayed out (non-functional) on my MUT3 driver. He said I could do it from the MUT3 but I can't find that command.Great find, if I understand correctly, it all comes down to the correct ‘file’:
- MUT3, Diagbox and similar are just a means to program the various ECU.
- The stock files that are available online (with a subscription) are encrypted.
- In order to flash custom mods one needs to find a way to ‘hack’ the file??
i doubt that they are encrypted, but just that they are binary or hexadecimal files of the load dataset.- The stock files that are available online (with a subscription) are encrypted.
IIRC Diagbox has an option to clone a BMU i.e. read (and store?) the current the settings, replace the BMU and then flash the new hardware, MUT3 must have a similar repair function.Yes, as I understood kolyandex.... he downloads the file from your BMU and modifies it.
