Summary of change:
'''Stock opel X20xev''' primary trigger 60-2 HALL effect Scope measure from stock ecu: 1V/Div http://www.vems.hu/files/CsotiF/scope.jpg Soundcard trigger played m582 with trigger errors. (but soundcard is rather like a VR signal, and it might not be proper for HALL input... For HALL input: negative voltage is not recommended at all) http://www.vems.hu/files/CsotiF/x20xev.png between ec36 pin 26 and pin 27 162 mV measured: it should be >4V in the other phase. (in gear 5 move the car slowly and watch with DVM). sj2 closed sj6 open R30=3300 ohm parallel with 27000 according to GenBoard/Manual/InputTriggerHardWare that's OK. The stock hall sensor is 14.4 volt supply Do I need any changes??? With the '''v3 connected to the sensor there is no signal.''' * Measured with scope ? ** EC36/pin27 should measure appr 4 .. 5.2 V when the sensor is disconnected. ** try to pull down the EC36/pin27 signal with 1kOhm instead of sensor * or with VemsTune ? ** that can be caused by misconfiguration also. In VemsTune, check validate ("check icon"). Check configuration carefully * [http://vems.hu/vt/help/main/error_reporting.html error reporting] step 1-2 almost done (this page)... Step 3-4 is exactly what should follow: upload vemslog and triggerlog Measured with scope and vemstune. The triggerlog is empty because its no signal from the hall sensor. The config is validated, its the default 4 cyl 60-2 no cam sync Trigger edge is Falling.
