Hello all. I have older programs that may help with less used functions.

@Matija, are you sure? I think it is p2 car (cem brick)... Config starts @0x8100

A remote for P2 Volvos come with 2 codes, the short code and the long code. In the first remote Short: 0D7D101F Long: 0A1C 2366 63D9 816D In UEM Eeprom, short code goes to address 0x0C to 0x0F However, the long code is changed from 0A1C 2366 63D9 816D to 2070 68DD 100D 1014 This code goes to addres...

I just succeeded

Thanks

Thanks for the reply. Yes, I do swap the large and small sequence numbers, but if I had made a mistake somewhere, the block would not have been diagnosed and the configuration would have been incorrect in CEMtool. For you P/N the shuffle order is nr.2 in array: https://github.com/vtl/volvo-cem-crac...

I tested around 10 versions of my TCM map changes. I have to say, they did not have the result I expected, which was to reduce the bumps, odd shifting of sticky solenoids. That being said I have more or less identified the main loop of the TCM, I know how it roughly executes things. I know which int...

Continue on my journey in Denso ecu for a V70 BiFuel 2006 Now when I have the rommonitor working it is easier to test code running in the ecu. Now with write support to external flash, eeprom and internal flash. Please, note that it is very easy to brick the ecu when replacing flash content. If new...

You can always dump it and send in chunks. Usually ping is high, its nowhere near 1ms unless done locally.

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...

Next small step with my V70 BiFuel 2006. Readout of CEM-L with M30855FW cpu using a SBL. Only read implemented so far. Decrypt of eeprom data is implemented but not verified that data is correct. It looks good, much more 0 values now and not just random. Parts that was FF (unused) now looks like ran...
