Summary of change:
'''Chrysler Hemi Trigger''' Since fw 1.2.17 also supported with camsync * In (new) VemsTune, from the primary trigger dialog, choose the Chrysler Hemi configlet (with camsync or without) ** preferrably after config from a similar (eg 8 cyl) engine is uploaded * Original implementation (2012-03-28 in 1.1.99) was without camsync * The pattern might NOT appear in the "trigger visual" in VemsTune ** even if configured to this "number of teeth on wheel"=32 and 8 cyl ** For this trigger, neglect any settings proposed by the "trigger visual" dialog. http://vems.hu/files/sensors/Trigger/ChryslerHemi/hemi_trigger.jpg ---- '''Pattern (codename m324 / M324)''' 17 teeth, 2 missing, 15 teeth, 2 missing tooth-pattern found on a V8 Chrysler HEMI engine, works perfect (thanks to Emil Larsson). Note: * '''choose the primary trigger edge, so that in the triggerlog, a block of 17 teeth is followed by a block of 15 teeth''' ** if the wrong edge is chosen, blocks of 16 appear (not good !) *** with some trick and camsync, it might (?) be possible to get that configured also (as N-2 missing-tooth trigger with wasted spark - but only supported with the correct setting: 17 / 15 teeth) ---- Example (first spark after ~1 camrot): http://vems.hu/download/sensors/triggerwheels/ChryslerHemi/hemi_camsync_works_2.png ---- Need help to sync Dodge Dakota V8 - a "High-Output" version of the 4.7 L PowerTech engine y. 2007. here is triggerlog: http://www.vems.hu/files/GintsK/Chrysler/Dodge.png http://www.vems.hu/files/GintsK/Chrysler/v3.3_u008395-2013-12-18-19.45.29.triggerlog I did not find how to sync it properly. Engines fires-up in 50% cases and shows too many sec trigger error all the time. 1.2.17 Secondary trigger is set to "rising", but seems it wouldn't change the signal timing significantly: http://www.vems.hu/files/GintsK/Chrysler/ngc_sensor_patterns_resized_154.png A: This primary trigger is supported by HEMI trigger, the secondary trigger pattern is not, is it possible to reduce secondary to one pulse per cam rotation ? - DB
