What is 'VSM'  . ?
I'm getting Variable Stream Mapping in google.

I have near 50 years working on cars, knowing dozens of 3 letter
acronyms about cars and fuel/smog/engine systems,
and I don't recall 'VSM' anywhere ever.    Took tests to be a certified
smog tech even long ago ..
tons of car tech acronyms on those tests  ....no VSM though.

so.. ?
