Summary of change:
Customer has a drift car, BMW with installed Dodge Viper 8.3liter V10 engine. Engine is odd-fire V-10 (90-54 degrees), firing order is 1-10-9-4-3-6-5-8-7-2 -------------- '''Primary trigger''' is HALL and trigger type is apparently coil-type (flywheel has 5 pairs of teeth, see photo). https://www.viperpartsofamerica.com/images/products/843_large_image.jpg EDIT: Trigger log: both primary and secondary trigger: http://www.porsche-foorum.org/album/displayimage.php?album=lastup&cat=0&pos=0 * [http://cell.dyndns.ws/del/viper/ same content in zip] * The 72 deg (10 cyl) seem to be 18+54 (18 deg=15.5 / 61.6 msec * 72 deg) * and 18 deg + sectrig comes after 24 crankdeg + following primtrig after 30 http://vems.hu/files/MembersPage/Peep/Viper10cylOddfire/Viper10cyl_oddfire_trigger_18_54__18_S24_30.jpg VEMS reads RPM but throws trigger errors * with what .vemscfg exactly ? Or better .vemslog ? * The config is definitely not good, the spark time is not consistent. Is it possible somehow to mask the 2nd tooth of each pair so that VEMS trats the primary trigger as coil type with 5 teeth? * search for oddfire or Maserati (fphil) ** eg. MembersPage/FPhil/CoilTypeOddFireConfig ------------- '''Secondary trigger''' is HALL, pattern is unknown at the moment. UPDATE: cam trigger is "half-moon" style: one teeth which is 180 degrees wide. ------------- '''Ignition system''' is wasted spark, 5 outputs is needed http://i.ebayimg.com/11/!B0)(jzw!Wk~$(KGrHqZ,!hYEw5P05ggIBMbvI+QelQ~~_35.JPG
