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,and also there is a single camsync (VR).We removed 1 tooth from the 12,90degs before cyl 1 TDC.

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

Looks like you got your crank trigger polarity wrong, the straight "lines" should be on negative zero-crossing, try to change this and see if its enough //Emil

Hi Emil,thanks for the idea,we tried both "directions",none worked.

I think we should check the ECU first.///pnanassy
