Title: Need Help With IMMO OFF and CKS ME7.1.1 (read done with ktag) Post by: irish07 on January 22, 2021, 12:25:05 PM ECU is a ME7.1.1 out of a 2001 A8L 4.2L
I've done a load of reading on NefMoto and believe I did this right to disable the immo. The file is only 1kb so none of the tools I've found will auto correct cks. Is the cks I need to alter located at 1E/2E(11/10) or 1F/2F(FD/FD)? I've attached a pic of the mod along with actual ori and mod eeprom files Summary: I changed 0x12 and 0x22 from 01 to 02..can someone confirm this is this correct? And for the cks (providing I knew the location), do I just increase the remainder value by 1 for each line? 00010: 05 01 02 00 3F D9 00 00 00 00 69 C1 00 A5 11 FD 00020: 05 01 02 00 3F D9 00 00 00 00 69 C1 00 A5 10 FD Title: Re: Need Help With IMMO OFF and CKS ME7.1.1 (read done with ktag) Post by: bamofo on January 22, 2021, 12:28:19 PM you set the right bit, but forgot to checksum it. Use this.

I increased lot by 1 per line (going from 01 to 02 for 0x12 and 0x22, which disables immo), you then need to minus value of 1 from the hex located at 0x1E and 0x2E(this corrects the cks)?

Yup. or download the EEPROM Tool on this site and do eepromtool.exe --in oldname.bin --out newname-cs.bin --fixcs Whatever your more comfortable doing. if its a single bit your changing its not hard as long as you remember its in hex and not numbers. |
