From some marketing propaganda introducing the M44 in the 1996 model year:

[The] dual resonance intake system [DISA], which provides two intake-pipe lengths to the cylinders according to engine speed, continues but has been refined to improve serviceability and match the new engine. It now changes from low- to high-speed setting at 4200 rpm, 600 rpm sooner than before and a good indicator of the engine's improved torque characteristics.

I'm tempted to add an LED indicating the change.
