RE:Anybody using one PMag and One Lightspeed? Any problems comments?
I am not but I have done a fair amount into the differences in the advance curve between the 2 systems. Although neither company actually sent me a copy of their advance curves I have gotten specific numbers for several different power/ RPM settings and the advance curves are quite a bit different from each other. At a given power and RPM setting the timing between the 2 systems may differ by over 10 degrees so one system will ignite the fuel air mixture well before the second fires. In that situation you would likely not get any more performance benefits than simply using 1 electronic ignition system and a mag for the other set of plugs. My advice would be if you want to go dual electronic ignition pick one system and stick to it. If you want one electronic system use a mag as backup. With a single electronic ignition you'll get most of the benefits (maybe 80%) that you would get with a dual system.
