Detailed Description

Igniter and RPM monitoring.

The sensor is a addition of RPM monitoring and spark monitoring. It measure the speed of engine, calculate the Ignition Timing and detect missing spark.

Parameters

Name	(string) : le nom du compteur.
Module	(CANModule) : instance of CANModule witche the sensor is plug. see CAN_Modules.py
Voie	(int) : the chanel is 0 AND 1 for igniter, don't use it.
NmbStrokeByTurn	: number of sparks in an engine turn. For a 4 cyclindres 4 strokes, it's 2 (default value is 2)
TpsInibSpark	[0-255 in 10µs] : time before accepte new spark. Spark duration ≈ 5ms BUT : on V8 @5000 rpm --> there is a spark each 3ms ! and 4 cylindres @ 7000 rpm --> 4ms ! (Default value = 10 (= 100µs))
TimeOffset	: offset of sensor of top dead center TDC (PMH in french) in° A positive value for a sensor detection AFTER the TDC.

Note: Inib time for rpm (engine) is not customizable, it's 5ms = 12000 rpm; Calculation of missing event : Missing if Number of spark < Engine Turns * NmbStrokeByTurn
