Summary of change:
== Nissan Timing Wheels == Considering that the standard trigger wheel's inner slot pattern looks like this: http://vems.hu/www.vems.co.uk/VEMSTech/NissanTriggerPulses.png Would the new trigger code correctly identify the pulses and engine phase? http://vems.hu/www.vems.co.uk/VEMSWB/S14CAS.JPG ----- The first cut of replacement timing disks has been done, and is documented VehicleFitment/Nissan/SimpleTrigger ----- In an attempt to 'normalise' the various Japanese trigger wheels to the 24 pulse (12 pulses per crank revolution) and 'n' sync (0.5, 1, 2...) - as used by Toyota, Honda, Mazda RX7. A candidate for the S13, S14, S15, also Z32, and later engined Skylines has been drawn. http://vems.hu/www.vems.co.uk/VEMSTech/24toothCASDimmed.PNG It will also be possible to get triggers for the GTiR SR20, S12 CA18 and KA, which have much larger diameter trigger wheels. == History and Detailed Information == Having looked at the Nissan Silvia and 200SX models (S12, S13 and S14) they all use a cam driven timing wheel with a speed sensor of 2degree resolution and portals of different sizes to denote the current cylinder. http://200sx.jagenheim.se/images/trigger.png == Nissan S14 Coil on plug == Now documented in VehicleFitment/NissanCOPs http://vems.hu/www.vems.co.uk/VEMSWB/COPAndSchematic.JPG Having checked the wiring pins relate to the schematic: http://vems.hu/www.vems.co.uk/VEMSWB/NissanCoilOnPlugSchematic.png
