Re: Vida CEM swapping

While porcupine is wondering how to effectively remove the CNG installation, I am curious how to convert to LPG while reusing most of the components(except tanks) so that the button + dashboard level works correctly. I believe the first step is to modify the REM module to correctly work with new pr...

Re: Vida CEM swapping

How would you recertify such a tank. You would need to xray it for any cracks caused by amortization aka metal fatigue. For commercial gas cylinders there is testing (welding gas mixes and such). I have no idea how they do this, but it is done. Not sure if they do it for composite tanks as well. I ...

Re: Vida CEM swapping

As my car have now the gas tanks reached the magic 20 year age I'm not allowed to drive it anymore. I am assuming this is a local regulation that requires the tank to be replaced or at least inspected after this period. Isn't there a way to get the tank replaced/certified again that is cost effecti...

Re: Vida CEM swapping

The problem is that Io-terminal and others cannot load SBL with a pin other than FF. So even if you know the PIN, you cannot modify the SBL to work with a different PIN? Would below scenario work? Is it even useful or would just using other method be just as fast/complex? 1. Read the PIN via other ...

Re: Vida CEM swapping

Так бесполезно читать в диагностической сессии, ну прочитали, а записать всё равно в ней не можем. Вот если мы можем переписать кусок с пином/пропатчить основную программу и PBL, то был бы смысл. Я не особо даже рассматриваю уже этот металлолом ибо тачки на них уже в стадии вымирания. По части терм...

Re: Vida CEM swapping

And that's why I'm leaning towards SBL for CEMB, because for example, in diagnostic mode, you can read the entire flash (512Kbytes), but it takes at least 20 minutes, and reading from the address in programm mode takes many times more. My test SBL reads the flash in 1 minute and 20 seconds, but so ...

I have decrypted eprom by io-terminal for compare.
I see that using my code I decrypt the first 61 bytes correctly.

Re: Vida CEM swapping

Hi everybody. I wrote SBL for CEMB to read the full contents of the flash. While in test mode, CAN packets are transmitted in uncontrolled mode with 8 bytes of data. 512 KB is transmitted in 1.3 minutes. The period between CAN packets is 1.192 milliseconds. I receive all data packets on the table w...

Re: Vida CEM swapping

What is it from? Hand made))) Not enough information. What device are you trying to decypher? Please provide all binaries you have. How did you get a 61 byte key? What cypher is being used? It doesn't make sense you have a 61 byte key, it's just an odd number. If the binary you are trying to decyph...
