Dear Microtronik,

I think it will be very useful for Autohex2 users to have Video showing how it works, as it is for other functions,

thanks!

Hi

It's very easy, just follow the wiring diagram and don't use solder, just touch the boot pin on the correct point, as you can hold the boot pin the because it only takes 20 seconds to read the EEPROM.

The most difficult part is opening the ECU, for which you should use a hot air gun to soften the glue that bonds both halves of the ECU together.

It's actually a very fast process, i can send you a video if you send me your email address or whatsapp.

Thanks

Thanks to Justin for this explanation :)
We will try to make a video soon, but I guess as Justin mentioned, the video time will be around 20 seconds only.

Thank you!

btw, do you guys use custom OBD2 adapter to connect Autohex2 to DME pins?
If yes, where did you get it?

We found 500+ cables in junk yard, you may find some of them there.

Can I have wiring diagram for OBD tricore boot mode adapter? I want to mainly understand what are the red, blue, green and aux cables connecting to and I also don't understand the boot pin schematic of MSD80, it seems some kind of a resistor is needed.

if you open any picture in ISN boot mode software, you can figure out the connection to the OBD female.
Only there is an internal resistor of value 120 OHM between pins 6 and 14 not shown there.
The red wires are connected to OBD Pin-1, it supplies 12V controlled by HW3 (and PC software of course)
I wish this explanation is enough.

Hi. Thanks again for the videos you have posted.
In you first video where you change ISN number in F series DDE I noticed that there was a so called Flip board ECU (to get to boot point you need to remove both metal ecu plates/ covers). It is not an easy ecu to open as the covers stack to the parts of the PCB. Do you have a special technique to open these ecus? Do you use heat or some sort of solvents to brake the grey sealant? Thanks

What is the coaxial part of the OBD adapter used for? Power supply?

Opening the DDE or DME is not our job :)
You can check in YouTube how they open such DMEs/DDEs and what tools they use.

Of course for power supply 12V

Hello my friend! :)
I really appreciate your effort to answer my question, but I think you could be a bit more friendlier.
I did not say that it is your job to open the ecus , but I thought that it would be interesting to know how you do it, and very likely that there are more people who would like to get some hints with that.
