Hi everyone,
Any of you lightspeed drivers ever seen your *indicated* RPM drop by half? Apparently my lightspeed loses track of one of the two (flywheel) magnet sensor signals, stops firing two of the cylinders, and reports half RPM. When I turn off my mag, sure enough, it's only running on two cylinders.
Oddly enough, it usually happens at startup for the first minute or so then goes away. But it's now happened briefly in flight too, so I really want to get this figured out. Heat expansion is an obvious suspect, but it can happen when the engine is hot too.
I've been working with Klaus from Lightspeed on this, and have changed my flywheel-sensor gap many times with no change. He's running out of ideas and so am I.
I thought I'd check here to see if anyone has seen anything similar. Thanks for any leads!
