Showing "---" is softwares issue.
All I can say is that OP-COM software it is original ( no cracked ) do not show "---" in mesuring block.
This was a normal issues when you usinga software version with a different data base as we know that VAUX-COM 120309a+131223d or VAUX-COM 120309a+160115a.
I cannot say that this is because of crack it show this. Neither because you are using it in windows 11.
Maybe because of your interface is fw1.95 which is using a fake MCU and actually the fw.1.95 is fake "good looking" fw.1.39 and this most probably could be your issue - No correct firmware in interface.
Well if you will try to flash the MCU ( Pic18F458 ) in your interface with the correct firmware fw1.67 you for sure will block your MCU forever ( cannot be fix it ).

You will need a good HQ clone in my opinion
Good luck

Can i just replace the MCU with original one and than flash with real firmware or will i need to make more changes on the pcb?

[mattydr67]

Usually the PCB needs a modification and the MCU should be flashed by an external PIC Programmer first.
If you will share your PCB pictures here I can tell you for sure. Because I saw PCB for normal/original MCU that has a "fake" MCU soldered by factory.

Good luck

Hi, this is my pcb 

[mattydr67]

It seems that you do not need to change anything on PCB.
First you have to downgrade the firmware using OCflah to fw1.39
Then use OP-COM 181022a EN to upgrade authomaticaly the firmware to fw1.67.
You do this by your own risk because if the interface it is still working then you have a good/orginal PIC18F458 but if you haven't then this MCU will be blocked forever and you have to replace it with brand new original flashed PIC18F458.
You will need an external Pic Programmer and you can flash the MCU using the programming pads on the PCB. ( your hardware PCB has programming MCU pads ).
Good luck

P.S. - when you change the MCU and you will need to do modification on PCB ( here you have how to do it https://cartechnology.co.uk/showthread.php?tid=5443 ) you will do it only if you cannot connect to the K-line cars.

Heres my board, looks like a good unit

[mattydr67]

Yes it looks like as HQ clone if you want a confirmation.
Good luck

Tank you, i actually have seen the programing pads, i think that the pcb is good quality just need to make sure that is original pic, witch i dont think so but lets see, i will buy original 1 first to have backup if something go wrong, than just replace it program the new pic.

If you have A1040 or A1050 instead of MCP2551 then you need to replace this one too if you want to have a real good connection in CAN BUS ecu.

Good luck

Hi,

I am willing to buy OpCom from Idiag to have a good working solution.
They are offering two different units:
OP-COM Version D+ (reellos)
and
OP-COM TYPE C

Am I correct that the Version D+ is the best?
