I'll be powering my RV-14 with the new EXP119 engine option (already on order). I had been planning on using one SDS ignition and one Pmag because I want to keep my electrical system as simple as possible. Although my Thunderbolt 390 WILL have the accessory drive where I could install a backup alternator, I don't plan on it at this time (maybe later if I choose to upgrade to full EFII).
My reasoning for wanting the SDS system may not be very well thought out. My knowledge here is sorely lacking. However, my thinking is that I could have two advance curves: one for LoP and one for RoP for better detonation margin under all conditions. However, I just watched the YouTube video, "Electronic Ignition Basics" and the presenter commented that a hybrid SDS/Pmag system would not see the benefit of the SDS system. Would that be true?
I'm also wondering if my reasoning is flawed in the first place (re: detonation margins and advance curves).
Also, how would you contrast a dual SDS (EFI or EFII) system with a dual Pmag system with an EICommander?
