MPPS V13 OK to read write BMW e91 325DAT 197hp m57d30 edc16c35

So I have this LCI BMW 325dat, want to tune it but im unsure if my MPPS v13 (no loader) and v16 (loader) can do this. V16 can't read the car or ecu id where v13 ecu id's and read flawless.

The file read is 1mb file size on v13 mpps, but i thought the ecu had 2mb memory? So will this be safe to get the file retuned and then write it in with mpps v13? Or will it brick the ecu.


Finally, had 13v and worked flawless with MPPS v13
