MPPS can be made much faster than it is by default.
Select speed "fast".
Turn off checksums in the ECU completely (EEPROM + FLASH patch).
Do not calculate checksums on your files, and use mpps to write. Write times for cal area changes will be 30 sec.
Any downside to running MPPS in fast mode? Any reliability issues? I know 2mins 25seconds isnt long to wait but hey.
