Summary of change:
I did test on car. Car works good, but trigger error is allays on(bad sec trigger position) Log: http://www.vems.hu/files/DamirMuha/1.1.89/v3.3_n002476-2011.02.15-17.00.13.vemslog ---- I have a car with Magneti Marelli cam (VR?) sensor(very hard to modify cam sensor), 3 sectrig teeth. 1.1.89 (and newer) firmware supports this * '''secondary trigger settings''' dialog ** '''ignore sectrig pulses above''' = 15 ** '''default 255 disables it''' ** this strategy can work for other missing tooth primary trigger wheels: the sectrig pulses after tooth 15 (or whatever config.secignore value is set) are ignored ** tooth0 is the tooth after missing gap, 0..57 are the toothnums for 60-2 Also should be good for the modified Cosworth, which using 36-1 crank trigger wheel, but need to use the original 2-tooth secondary trigger! * orginal cosworth cam has two impulses 180deg(90deg on cam) apart ---- '''Trigger details''' * [http://www.vems.hu/files/DamirMuha/v3.3_n002476-2011-01-27-17.37.13.zip Trigger log zip] * '''Sectrig pulses at: primary trigger tooth = 13,43,51''' * primary trigger is 60-2 (trigger tooth=9 64deg before tdc). ** If vems ignore sectrig pulses in range 130-150deg before TDC that leaves only one pulse per cam rotation. '''Note''' * it doesn't matter if many sectrig pulses come, as long as all those pulses are in the same crankshaft rotation (starting at tooth0 of course, NOT TDC) ** they don't cause operational problem with missing tooth primary trigger wheel (if camsync bad position is configured to flag only, not to cut spark). ---- '''When is this strategy not applicable''' ? * coil type primary trigger ** like the InputTrigger/LanciaCosworth requires * when the first sectrig pulse after the primtrig missing tooth comes at the same primtrig tooth, eg: ** 7, 19, 60+7 .. than the config.secignore=6 would eliminate all, 7 would leave both. We don't know such weird campattern (but anglegrinder could help to teach it some etiquette).
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
