Stock opel X20xev
primary trigger 60-2 HALL effect
Scope measure from stock ecu:
1V/Div
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)
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
- [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.
The parallel resistors defining the disconected voltage on pin 27? (sould I put 1k instead of 3.3k?)
If there is no pullup in pin27 then the sensor is not making signals?
If only the scope is connected to the sensor and the supply there is now signal. (Plug the stock ecu then trigger is there )
When the stock ecu is connected ignition on mesured 182 mv on sensor conector.
Car is running, repleaced hall effect sensor with vr. Trigger hardware reconfigurated.

How to set ve table over 255 kpa?? or fuel cut over 255??
