(electronics)
To adjust for resonance at a desired frequency.

tune

(jargon)
(From musical, possibly via automotive, usage) To optimise a program or system for a particular environment, especially by adjusting numerical parameters designed as hooks for tuning, e.g. by changing "#define" lines in C. One may "tune for time" (fastest execution), "tune for space" (least memory use), or "tune for configuration" (most efficient use of hardware).

See bum, hot spot, hand-hacking.
