To maybe save some precious time while talking about "Volvo ME9":
Volvo ME9 exists with two projects.
P010xyyy for Platform P1X - has no KWP or UDS, only Volvo D2
P020xyyy for Platform P3X - has UDS / KWP
For security access you have vehicle specific random generatd seed. Without it no flashing. Don't remember if needed for logging... Neither of them are UDS. P02 service stack is KWP. Good to know about P01, I'm working on P02 for now. Security for memory reading in ASW and flashing is a completely different thing. |

Volvo defined it as "implenting" iso 14229-1 according
to all documents and tools for internal development.
What makes it non UDS in your opinion?

I did not dig deep enough to check if it's some sort of hybrid. E.g. KWP services present, but services that have same identifier have UDS format. So I don't know if some newer ones exist that are UDS or not. Looked at a P01 and that has also some minimal services present. Probably needs a patch for logging though. Or implementation of proprietary protocol. EDIT: ECU I bought is P01. Do you know if P01 and P02 are hardware compatible (e.g. P02 file will run in P01)? If not, I probably should buy a P02 too. |

Are you planning on supporting P01 in advanced logging mode? |

I probably will be able to. The Ford A2L I have is way closer than the Volvo P02 A2L, and most of the RAM cell values are found for P01 using the Ford A2L, so I think the result is good enough. Now to just figure out if I can dump a P02 BDM dump into a P01 ECU or if I need two separate ECU's. For P01 though a patch will probably be needed (unless I decide to implement the volvo proprietary protocol I guess). P02 hopefully without. IDK if any tools do full write over OBD, or if it's going to be a BDM job. There's a header on top of the board on these, used it a few times on Ford, but kinda annoying. |

I will be trying to flash P2 binary to P1 ECU through BDM so I can report tomorrow evening if you will find this information useful. EDIT: I can also test the advanced protocol/patch on a P1 car, will happily pay for the logger. If I can be of any help. |

If you can test and report whether P02 binary boots in normal mode on P01 hardware, it could be useful, so I know if I should buy another ECU or not.
No need to test anything else, since I'm going to have an ECU on the table for the development.

Does anyone know how I is calculated for the logger? Also, how does the bitmask work? Name , Address, Size, Bitmask, Unit , Signed, I, Factor, Offset, Comment
gangi , 0x3006C0, 1, 0x0000, gear , 0, 0, 1, 0, Selected Gear
nmot_w , 0xF89E, 2, 0x0000, rpm , 0, 0, 0.25, 0, Engine Speed

Well, it did not boot. So good thing that you ordered P02 ECU. |

To change evap from US to EU version I need to
change the ESKONF from 0C 00 0C F0 00 FC 00 to 0C 00 0C FC 00 FC CC
or something more?
I have EU S60R.

What kind of difference is between US and EU evap systems? |

US version e.g. has Leak Detection Pump, EU doesn't have. DTC: ECM-4010, ECM-4024 |

You can just disable leaks diagnostics. Or check US and EN ESKONFs. I just set CDTES to 0. |

Could you please point me to where I could find CDTES (and CDLDP?) in a QKHJ file? I haven't come across an EU QKHJ bin yet to compare with either... My ESKONF looks like this: My QKHJ US
0C 00 0C F0 00 FC 00
GPHJ US:
0C 00 3C F0 00 FC 00
GPHJ EU:
0C 00 3C FC 00 FC 33
Would changing the 4th byte to FC and 7th byte to 33 do the trick? Thanks! |
