Sometimes if code is not disassembled in correct order, you get weird result and need to start all over a fresh disassembly, following exact steps so IDA can setup internal registers first. In code various registers are repurposed in the code flow and program needs to track them. Usually you will ne...

These are the built in offsets how cpu sees code in memory. Not sure why it is configured that way. I do like IDA and never used ghidra so can`t speak which one works best, Both have pros and cons. Before final analysis you need to specify r2,r13 and manually convert into code vectors, at start of 4...

Smaller bin goes to 400000
Main bin to 0
calibration 5c2000

And you are good to go.

Just a general info that might get you started, based on similar ME9.6 layout and some a2l floating on the web The memory layout of calibration data starts at 5c2000 in disassembly [in bin it starts at 1c2000] The smaller bin should go at 400000 . The bigger bin goes to 0 It should be close enough. ...

Can you select device as serial with com port and not as j2534 device.

You have no communication with PCM. Something is wrong with setup, cable, or pcm is completely dead.

This sound like another option configuration data stored in eeprom. And it can be easily reconfigured using bus messages, if onboard code supports it. I don`t want to make the method available here. The nec site just ask for simple account creation. Don`t have one but you can give it a go, ans see w...

You might get lucky, once you dial the communication issues you have.

I looked at tech2 data for this dash, It doesn`t even have a mileage on the datastream[only trip data],...

That is partly due to missing tutorial. Can you give some screenshot what happens or log, is there any idle traffic from ipc on screen. The usual usage will be settings-> select device->configure device->connect button. On vpw console there is various checkboxs-> ->>screen checkbox prints traffic to...
