We have a problem with a trigger system.
Its on a 4 cyl H22 Honda 2.2 liter engine.Space is extremly limited.The stock crank trigger wheel (VR sensor) has 12 teeth.
Camsync (VR) was extremely noise, decided not to use.
We removed 1 tooth with angle grinder from the 12,90degs before cyl 1 TDC.
- VR sensor measures: 2000 Ohm
- 0.5V measured (with 18k internal pullup this is reasonable)
Here is a oscilloscope capture.Camsynk is too noisy.
However,we do not get any kind of RPM signal with VEMS,not even with Triggerlog.Wiring must be ok because the oscilloscope shows the signals. Maybe the ECU is faulty??
Please help ASAP.thanks///pnanassy
This trigger polarity is definitely wrong (the straight "lines" should be on negative zero-crossing). The signal was inverted since.
Also, we will try "Advanced filtering", to change the default 150% threshold between 175%
The 1.62 below indicates that tooth time at a normal tooth is higher than 1.5 x previous time.
