works fine
Axel,
I built a RV-9a in 2004 (currently 450 hours) with a O-320, one lightspeed (crank angle sensor) Plasma II and one Slick. The combination works very well and is a conservative way to get your feet wet with electronic ignition.
I've subsequently built a '8 and installed 2 Plasma II's. Works even better, but you do need to install some sort of backup power supply.
With one mag and one lightspeed you will find that during a typical runup (1800 rpm or so) that the lightspeed is carrying virtually all of the load. If you shut down the mag you'll see somewhere between 20-60 rpm drop depending on temp, humidity, etc... (mixture) with NO discernable change in noise, vibration, etc. But when you shut off the lightspeed the mag will drop 150 - 175. This is expected and normal since the lightspeed is probably firing a bit before the mag.
As to service. I've had the mag disassembled, cleaned, retimed and reinstalled. Fortunately no brush issues (current AD). The lightspeed has had NO service, NADA, NONE. I generally remove the mag's plugs at annual and clean them and regap them. They always have lead fouling (not bad, but always present) The auto plugs on the lightspeed are always removed, look fine, and thrown away and replaced for $2 apiece. Probably would run just fine for another year, but I replace them since they're cheap.
I would'nt hesitate to go this route if you want to try electronic ignition. When the Slick fails and needs serious rebuilding, sell the core and buy another EI. Maybe a PMAG.
All,
I did a search and found some data on this topic. I was wondering if you can tell me your experience from running one Slick mag and one EI. The pros and cons that you have run into. Difficulties? Gains? I currently have two Slick mags installed on my engine but want to explore the option of one and one. Now that I have switched to fuel injection and cold air sump this maybe the last engine mod. Thanks for any guidance.
