Summary of change:
vems 3.7 board vr/vr setup need changing over to vr/hall engine '''BMW m50b25tu ''' * '''primary trigger=VR''' 60-2 crank ** R30=18k (but 10k or 27k should also work). You probably do NOT want to change anything around primtrig, since primtrig=VR already (1k would be too strong anyway) * '''secondary trigger=HALL''' sensor on cam ** '''Changing to HALL should be simple''', see GenBoard/Manual/InputTriggerHardWareSectrigHall ----------------------------------- bottom view https://drive.google.com/open?id=1eMa0XuRHrnh7cIYlCcI1ERID85F0nHxQ top view https://drive.google.com/open?id=1HEHAyxgnL-CFirkSctx10CqGjVuHbLED * I understand that the '''sj7 which is closed need to be opened''' ** yes, unsolder ---- '''Also: apply the short according to small slanted line''' http://www.vems.hu/manual/html/images/Testing/v3.6_sec_trigger_1_m.jpg My image looks diff at this point: https://drive.google.com/open?id=1WQ8ZMNXJSmv1sGjeOYzjHtMW9af0N-gW * Of course different, because configured for VR * the '''manually SOLDERED 2k7 (2701) resistor must be removed''' ( on your pic: at 4 hours from the southern end of hotmelt) * R48 must be installed (input signal pullup: 2k7..4k7) ** some hotmelt seems to be over the most convenient place for sectrig input pullup, remove hotmelt before soldering ** soldering the removed "2701" 2k7 could work if not damaged, but the rescuekit (small bag included with devices) should have new resistors About '''the other 5 holes''': * there is a wire attached at another point on the board redwire on the bottom view ** do i just disconnect it ? ** goes toward LM1815 pin3, should not matter. I would leave that, do the other mods, and test that way (remove if necessary, or cut+insulate or cut both ends, but it should not matter). First '''input tests:''' * input disconnected: DC voltage measured >3.7V * 1k between input and GND (instead of HALL sensor), DC voltage should measure: between 0.5V and 1.5V Than '''verify in InputTrigger/TriggerLog'''

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.
