Summary of change:
Subpage of MemberPage/MilanaPerisic '''Primary trigger VR 60-2''' * measured sensor 516Ohm * [http://www.vems.hu/files/MembersPage/MilanaPerisic/config.txt config] and [http://www.vems.hu/files/MembersPage/MilanaPerisic/tables.txt tables] ** primary_trigger= 01 '''Primary trigger pullup''' I removed the R30 but now engine is totaly dead,no spark,no RPM readings in MegaTune... * Q: Why do you remove R30 ? A 10..22k pullup on VR trigger input makes it more tolerant to trigger noise. * A: Ok,10k R30 removed.In manual its says if the R30 is there it should be unsoldered Hint: * Important: '''measured DC voltage on trigger input''' ? ** with R30=18k pullup, should be around 516 * 5000/(18000+516) = 139 mV *** TODO '''Secondary trigger''' * not used ** secondary_trigger=02 ---- '''Trigger problem''' - reverse polarity VR ? '''Problems solved.Mcell was right,polarity was reversed''' * firmware version : 1.0.73 * [http://www.vems.hu/files/MembersPage/MilanaPerisic/config.txt config] and [http://www.vems.hu/files/MembersPage/MilanaPerisic/tables.txt tables] * Multitooth 60-2,VR While cranking, I got trigger errors in MegaTune * I replaced the sensor and did better groundings on VR,still the same While cranking before getting trigger errors rpms goes up to 740 and for a second to 0 and back up to 740,it looks like engine wants to start but for some reason it loses every signal for a second and then back on. Using stock missing tooth 60-2 with stock VR http://www.vems.hu/files/MembersPage/MilanaPerisic/trigger-settings.JPG Cranking engine log: http://www.vems.hu/files/MembersPage/MilanaPerisic/mt_datalog_m20.zip InputTrigger/TriggerLog: * [http://www.vems.hu/files/MembersPage/MilanaPerisic/trigger_bmw_m20_log.zip raw terminal-log zipped] * [http://www.vems.hu/files/MembersPage/MilanaPerisic/trigger_bmw_m20_log.txt formatted txt] ** looks reverse-polarity: <code> 354 1455 1 355 44806 1 356 1429 0.98 357 38157 0.85 358 3234 2.26 MISSINGTOOTH 58 359 41224 1.08 360 2216 0.68 361 43013 1.04 362 1358 0.61 363 19974 0.46 364 1372 1.01 365 23557 1.17 366 1418 1.03 </code> The left side has the meaningful data. It seems you get 2 longer gaps (3234+ 2216=5450 that is 4*1363) instead of a proper almost 3x long (around 1400*3 = 4200 would be proper). '''Your VR sensor seems to be polarity-reversed.'''
