Today, there are 3 types of Translators available:
Basic Translator (BASE and WOT fuel knobs)
Translator GenII (extensive fuel/timing adjustments + WOT WBO2 tracking)
Translator Pro (even more extensive than GenII, plus primarilly designed to run speed density (mafless)).
The Translator Plus was dropped when the GenII came along.
Back before the GenII and Pro came along there were two:
Basic Translator (BASE and WOT fuel knobs)
Translator Plus (BASE and WOT fuel knobs and BASE and WOT timing knobs).
The difference between these two is in the Plus, BASE and WOT timing adjustments were added
