Lycoming EIS Mag Replacement

There's quite a lively thread about the SureFly electronic ignition going on right now. The main gist seems to be the timing curve that SureFly uses and the pros and cons of using it. Instead of hijacking that thread I figured I'd start a new one.

Has anyone had any experience with the new Lycoming EIS mag replacement?

Lycoming says the hardware is produced by Surefly but the firmware/software is all their's.

I can't find any info on the timing curve for the Lycoming EIS but from my talk with the rep, it's definitely different. You would think it would be compatible (curve wise) for whatever Lycoming it was certified for.

That was the plan when announced at OSH last year.
