Hello from Poland

Greetings All,
Greg here, living in beautiful Polish mountains. Computer sience engineer, tinkerer, did some electronics and software developement in my life
Planning to build a turbo M50B30 car, so I've found RusEFI and Speeduino projects very interesting while searching for an alternative SA solution.
After I met Kris ans his SCG-ECU and his idea to use STM32F407VE board as a core for Speeduino I had eve more crazy idea: Create one board compatible with both softwares, so I plan to use STM32F407VG (1MB of flash). The plan is to make a hybrid of Frankenso and SCG-ECU 1.0, add some EEPROM, build a reasonable hardware arround it, try to put that into one of the AliExpress ECU enclosures, add Ion Sensing knock detection (3 channels for up to 12 cylinders). There are already 12 high current channels on both boards, so with batch igniotion there's a chance to aim at V12 engines I believe.
The idea brings my first quesion here:
Where does RusEFi store all the maps? There's no EEPROM on the board. So? Battery backed-up SRAM? And if bat dies, then loading maps fro mthe scratch? Why not store that in an SPI EEPROM and load on boot to the SRAM?
Looking forward
Greg
