When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Sensor itself is just half of problem. Other is some data analysis equipment. Simple o-scope here is not enough.
I agree Gints,but it depends what do You really want to see.If You wanna see exact point when the peak pressure occurs (deg ATDC), then You need something to calculate that angle from TDC (camsync) sensor and RPMs,and if You need simple knock indicator,than You actually need to know pressure level.I mean when knock occurs ,then in cyl. pressure is much higher then without knock.
Any new spark plug which can measure cylinder pressure? Any cheap?
