Optimizing spark plug ignition timing.

It is seen in Plexlogger

By capturing data signals for cylinder pressure at the moment
of spark plug ignition and cylinder TDC and simultaneously
recording piston movement and data signals, it is possible to
check the optimal ignition timing and to conduct an analysis in
order to increase combustion efficiency.
