I'm note that there are no any working solution to compare and save the changes of files OnLine which will be accessible to everyone wants share the experience.
So I decide to make small program to store my work for some cars and apply it to the new one.
It's a binary patcher able to compare and detect byte shifts of 2 equal size files, save it to the .patch file, patch and unpatch the files, compare results.
Note - to create patch use 2 files from one particular car to leave untouched immo bytes.
It can be useful to work with ECU without checksum and when the checksum is not calculated on the tuning areas OR it changes will be linear to changed bytes. If not - use loader with sum correction or additional soft.
So the URL is
http://www.nbns.ru/bin/
I post a sample files in mitsubishi/eclipse directory.
Anyone who want to test 2 couple of files please welcome
If it's an interest idea and you want to develop the base - we must discuss to make it on good hosting, mine one is poor serious work.
Glad to see you opinions!
