Default RE: Opensource CDI ignition

What's that 6pin chip for? Is it a part of advance or part of HV circuit?
The 6 pin chip is a optocoupler placed between HV and advance to eliminate interferance from the HV.

Is schematic on the http://www.modelbouw.gompy.net/cdi/cdi.htm working or you already changed it ? Which program should i burn in the chip :Zenoah 2.hex?What if i want to change advance settings?Which spreadsheet do i use then?
All schematics on the site are working.
It depent wat hex-file you will use, the Zenoah-file ingrease the ignition......not all engine love this.
The best way to use the timingtable is, start with all settings on zero (no delay)
If your cdi is working, start with a small delay (1msec) for the complete table.
If everything goes fine, make your own table for your engine.
BTW, most normale engines have a degrease table (ignitionpoint + x-degrees)

Bigboat please advice!
Wait untill we (JMJ and I) are ready with the new cdi.
I put everything online if we are ready and will post the link here on the msgboard.
