Title: ME17.2.4 ECU BMW BMSMP EEPROM CS1 CS2 help needed Post by: BMWS1KRR on January 25, 2021, 04:55:59 PM I need a CheckSum calculator for EEPROM CS1 and CS2 for both the BMSMP and BMSO ECU's.
Always willing to contribute in some way if needed that I can help or ? Seems still no one but WinOLS has a CKS calculation that can fix the EEPROM once you change the VIN or any other data in the 192K file. I have a need to modify more than 2 or 3 files. I have had people offer to take my ORI and MOD files and fix the CS1 and CS2, but I need a standalone method. Even if it is pen and paper calculations or a nice piece of software. EVC wants over $2000 for the current WinOLS so that the current OLS CKS can be used as it will not work in the cracked 2.24 version. IMMOFF17 never released a version that does anything other than the 64K file in BMSX. Can someone please PM me or post a solution? TIA..

CS2 @ 0x7c = CRC32 of 0x8->0x77 (init with word @ 0x78) CS1 @ 0x02 = lower short of CRC32 of 0x4->0x7f (init with short @ 0x0) CS2 first, then CS1. Immo block IDs = 0x8, 0x9, 0xa Crc poly = 0xEDB88320 All little endian.

you have Skype?

I can pay for you to teach me. do you have skyper or whatsapp? it's better to talk Title: Re: ME17.2.4 ECU BMW BMSMP EEPROM CS1 CS2 help needed Post by: Arthur1808 on June 28, 2024, 02:41:39 AM Hello
anyone find how to calculate checksums?
