We should patent "Change the performance characteristics of a motor vehicle by use of a pedal" then sue everyone  |

How is this looking? I've just bought a spare ECU to immo off, but it's already the HJ 0002, so I'm gonna look at the file already posted here.
The problem is, I don't have cruise. I'd like to change it for brake + throttle. Feedback via rpm or MIL would be lovely. I'm gonna get it loaded into IDA but I'm still pretty new as how to set it up.
Once I can get it in IDA, I can probably make up my own, but I'm unsure how to load the file in IDA properly. Offsets, etc.

I remember reading that thread but had forgotten. Thanks very much! Hopefully I can start to understand.
Assuming I would create my own module/subroutine in IDA, export it to a compiler, compile it and then inject it at the appropriate location?

In ida you can only write this in hex and just check what you did..If you would like to wirte it and comiple it use keil for c167. Use the search on the forum while you are at the main forums.

You can use IDA to change things though like ram refs, new or expanded functions compile yes |

I want to implement this feature in my files too, when I get started on it I'll post my assembly and bins here too. Will be a bit (well actually 512kb) different since its narrowband, but I'm super motivated and have done a lot of reading on the topic so far. Is there any description on the function of RPM needle for showing the maps, or was this kept private?

Hi, thanks for response but I don't have ram logger. I allready found the few routines that read and write the EEPROM. Now I search for places where them are called and the passed parameter will give me the answer where the RAM location is  br - cruuz |

IMO serious assembly work is going to be impossible without one |

hi, it took me a day but here you have it: for 032HN-Box 363908 the mirror starts at 0x383B1E this means : EEPROM 0x010 := 0x383B1E in RAM and e.g. EEPROM 0x1b0 :=> 0x383C4E don't have a car or an emulator if somebody could test something like: mov r14, #102h extp #0E0h, #1 ; mov 0BC50h, r14 ; 383C50h and read after EEPROM with KTAG or some othe tool would be nice br - cruuz |
