Hi Bernie,

Again, I assure you our cdi does what it is told to. It can do up to 50deg. advance at any rpm, if one wishes.

To clear things up, the timing curve in modern oem cdi is defined by software: the pickup coil catches the tooth beginning and ending, and times the ignition in between to produce the desired advance, which can vary with rpm at the designer's will. It's the same in our box, but we made it user controlled with our Windows application for that (or with a jumper, for the simpler case).

You're giving me the push to return to the dyno soon (another one, not the same as two years ago)...

I had a look at that cdi unit... never seen such a thing...
the adjustable advance in units I use, there you actually change only the advance curves up to 5000rpm.but not the total advance. In that box, when you change to another curve, you change the entire thing, bottom and top... that's why I said, the static timing is different to the advance curves..they only work under 5000
anyway...the problem must be in that box somewhere..otherwise it would have shown differences (big ones) on the dyno

Hi! Are you the PaRay guy? My KLX will fire up and idle fine, but then die at 4000 rpm, or sooner if gunned. My dad seems to think ignition, especially since very often when running steady the tach will "blip" for just a second... almost not noticable, but still there. Now it just dies on rev. The other option is carburation, which I won't get into here. There is a PaRay Electonique cdi available used locally... just wondering if that's you, and if you think my issue is ignition related. Thanks! Tim
