Hello everyone. i am new here and with motronic too.
Can anyone tell me when i can get memory mappinng of m4.3-m4.4
i have 850 with 4.3 wiring and separate 4.4 mcu and i want to install additional mcu in m4.4 that will pretend as parrallel memory so when main mcu will ask for data (firmware) my mcu will give it.
Main advantages: fast firmware switching, usb connection, real time data changing and so on. also i am free to make windows running program that will connect and affect on firmware that handles ecu.
Things that ive need to know - where each data is stored in firmware (fuel maps, timings, boost and so on) also checksum type (where checksum stored etc)
i am programmer and developer so i think with all additional data i can do it - it will be interesting for me and maybe for someone else. instead of memory i want to use 480mhz ARM mcu, that can handle everything.
