VEMS on 7A flywheel - Scope

Flywheel

Hi,

I have a next problem. VEMS detect primary trigger in log file but secundary trigger no.

Actually i use camHall invert is OK and i measure with scope JP20 signal directly ( Secundary trigger VR ) and CamHall input in EC36-13.

By datasheet of LM1815 in MODE 5 put at 5V the output is active if measure peak-to-peak more that 200mV. Actually i think my problem in reference pin in 7A flywheel. I have peak-to-peak " only " 200mV.

Anyone confirme if the problem is it?



Many thanks.

I think you have the same problem as i had with my MaxxEcu and 7A-flywheel. It "triggers" on the groovs in the flywheel. You could do the back on the flywheel flat or go with another flywheel.

Jep, same here. I knew the problem and did it first i installed the flywheel with maxxecu. But guy i know did at first and had the same problem that trigger picked up wrong signal.

I'm not sure, but have you noticed that your flywheel pin signal does not cross 0 ? lm1815 triggers when signal crosses zero. who made auditrigger circuit? you by yourself? i mean you got ecu like this from vems or somebody modified it?
