'''RPM=0 => Tools/capture triggerlog''' so we can see which trigger seem to be missing * [http://vems.hu/vemstune/bugreports/reports.php?cmd=view&key=oKLJqH#comments vemscfg can be found in the report zipfile] ** [http://vems.hu/files/MembersPage/MorneAudi/morne/ vemscfg file], also default AAN file and the "diff -U2" difference ** no serious problem in the configuration at first glance: ** prohibit seems good for 1.1.96 ** configswitch is disabled ** some calibration values differ (good) * '''vemslog: STILL not available''' ** click on "LOG" icon until it becomes green, attempt startup, publish the related file from VEMS_Files directory * '''triggerlog: not available''' (important if RPM=0) ** '''Tools/Capture triggerlog, attempt startup, publish the related file from VEMS_Files directory''' * we would need to check the '''RPM at the startup attempt''' ! ** is RPM=0 at startup ? ** or RPM=normal (around 180) ? Or nonzero, but abnormal (if so, how) ? ---- '''Ignition outputs...''' * Ignition outputs visual, switch to test mode ** '''important if RPM is good at startup attempt''' * Did you see spark ? (use a sparkplug on the cylinderhead, make sure sparkplug-body is actually grounded to cylinder head). Do not touch ! * '''All 5 High-Voltage channels work correctly ''' ** yes, sparking OK Be careful ! * maybe it's something as simple as blown fuse ? See [http://vems.hu/vt VT help] and tutorial videos. ---- '''Measurements''' Note: triggerlog was not uploaded, but the images show something surprising: * The "Camshaft exhaust" is surprising (1 tooth for every 90 primary trigger tooth is OK, it's 270 divby3), we're investigating why it is not "secondary trigger". http://www.vems.hu/files/MembersPage/MorneAudi/morne/audiAANnew_sensor_log.png http://www.vems.hu/files/MembersPage/MorneAudi/morne/audi.png Copied from [http://vems.hu/vemstune/bugreports/reports.php?cmd=view&key=KlHx4b report] (note: vemslog was not captured or not included in this report either) log for audi s4 aan ignition coils tested ok measurement sensor ohm between 44/30 ,728kohm ohm between 45/30 2,69kohm aan pin 10 0,4ohm aan pin 19 1,3ohm aan pin 24 1,2ohm aan sensor pin 30 4,7mohm * measurement trigger 49/48 1kohm ** '''ALSO MEASURE pin49 DC voltage''' (ignition on, engine off) * measurement trigger 47/48 1kohm ** '''ALSO MEASURE pin47 DC voltage''' (ignition on, engine off) * '''aan sensor triger 48 open''' ** What does this mean ? Sounds to contradict the above 2 measurements (if "open", then it would be infinite ohm, not 1 kohm Symptoms * no start * no spark tested ** why not ? * '''no rpm signal''' ** Assuming RPM=0 * do not know which firmware has been used Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
