Pressure compensation

Until the arrival of the pressure transducer, peak cylinder pressure was our primary concern when measuring engine compression.

With the WPS500X on the scene, we are introduced to superior cylinder pressure analysis in the form of positive/negative cylinder pressures, valve open/close events and valve duration, to name but a few.

What soon becomes apparent is the discrepancy between peak cylinder pressures when measured by a traditional compression gauge, compared to the WPS pressure transducer.
