Title: KTM 690 stays advance when hot
Post by AlexE on Oct 1^st, 2012 at 6:07pm

Hi there, here is my very first post,

i need to overcome the steep learning curve of this instrument,
for stater this bike has a KEIHIN fly by wire system. once hot if you let go of the throttle for said a traffic light she stays advance, today a recorded this trace from the magneto pick up sensor(pulse generator). can any one please tells me what do you infer from this trace. :-[ this trace is at idle, and could this be the reason for this engine stayed in an advance mode.

Thanks in advance for your help.

Alex,

For any PicoScope help issues, post in the Picogroup area.

I don't know what that is supposed to look like. What are you seeing in that capture that you don't like?

I see some noise in that but you are using a very high sample rate so that is to be expected.

May I suggest you do not use AC coupling.

Will do Tom, thanks, so I should use DC setting and BTW what is an AC coupling :-[
