SIO DC RPM, Ignition timing.

Hi Guys
Can any of you clever lot inform me, will a full DC Wassel Conversion interfere with the ignition timing? See 'Sip2 Installation' If need full details.
I have joined the Brown RPM of the Sip 2 to one of the yellows from the Stator (BGM DC) this was the only way I could get correct and stable RPM, would this have any bearing on the Ignition Timing especially on High RPM?
