I will dedicate this post to the cdi here: http://www.modelbouw.gompy.net/newcdi/newcdi.htm

With all respect to the designer I feel it necessary to outline some errors I found with this project.

I have built and tested this cdi. Built as outlined it "will not work".

I downloaded all related info for this maybe 8 weeks ago, since then at least one change has been made.

The two biggest errors are the wiring connection for both the sensor and led strobe as shown on the component layout. With these wired as per the diagrams I received the cdi will not work in any mode, test or normal.

Pictures below show sensor connections that have been corrected by designer in last month or so.

P to +
- to P

LEDs are polarised and must be orientated correctly. Have a look at both the pcb and component layout. Component layout shows to wire led incorrectly. It puts the kathode or - on the positive 5 volt rail.

Corrections to parts list to follow.

It appears the "last update" on this site is a calender and changes every day. So it might be that nothing on the page is actualy being updated as you would expect.
