The "Dark Side" of 1.20

It would be dishonest to review PCM Flash 1.20 without acknowledging its reputation in the darker corners of the industry.

This version is infamous in forums for two reasons:

It allowed legitimate workshops to offer Stage 1 and Stage 2 tunes without buying a $10,000 system.
It allowed amateurs to brick cars because they skipped the "Read" step and went straight to "Write" with unchecked files.

It is a testament to the software's core stability that even with misuse, it rarely damaged hardware on its own—the protocols were solid, even if the users weren't. PCM Flash 1
