I really like the timing advance on mine.  It’s not a huge difference, but I get a little more power out of it LOP at higher cruise altitude.  The 14v SF seems to work fine, but I’m not sure I’d do the lyc branded due to fixed time and possible issues?

yeah, as i recommended above, the lyc mag was failed experiment for me after trying two, and then lycoming admitting there is an issue, no way i could recommend someone knowing going into that mess.  so far (one long flight) the surefly ran flawlessly.  (surefly and power conditioner, 28V)

Also, good luck getting any of these companies to pay for your complete R&R when something goes wrong...never mind your personal time dealing with it.

That seems to be common now, customers beta testing their product.

That’s not just GA, spirit was the launch customer for the NEO engine. We were chewing up a motor once a month for about a year. Once we ran through all the spares Pratt & whitney had we effectively grounded the fleet. Come to find out 45 mins between shutdown and start up was the worst possible timing for heat soaked rotor bowing. I guess in testing the engines they would sit on the ground longer than 45 mins before doing another flight. The workaround was a 2 min motoring of the engine before starting each engine.
