Edge selection for camshaft trigger wheel signal
Frequently, when a variable valve timing system is present in an engine, incorrect signal edge
selection makes proper signal decoding impossible.
Incorrect scope for camshaft trigger wheel signal
The scope above shows a camshaft trigger wheel signal decoded with equal distances between
signal edges (teeth). This configuration prevents clear engine stroke detection. After edge change,
the decoded signal is clearly different between engine strokes. This makes possible to use
camshaft trigger wheel signal decoder ( N+1 in this case )
