High-speed data logging or heavy ECU reflashing is

MVCI_HANDLE mvci_open(int device_id); BOOL mvci_read(MVCI_HANDLE h, UINT32 addr, BYTE* buffer, DWORD len); BOOL mvci_write(MVCI_HANDLE h, UINT32 addr, BYTE* data, DWORD len); BOOL mvci_ioctl(MVCI_HANDLE h, DWORD code, void* in, DWORD in_sz, void* out, DWORD out_sz); void mvci_close(MVCI_HANDLE h);
