Bad idea.
Jet uses a license every time you read a PCM. A new interface comes with 4 licenses, they will be depleted quickly.
You may want to look for a different solution.

It's been a while since I used test mode with JET, I don't know if the current version still has the mode available. If it does yes you can save as BIN.
I can convert the JST to BIN, however some...

It does not work, I have both.
I tried both ways: AVT cable with Jet DST and Jet DST cable with Winflash, no avail.
