As you say, anyone who wants to take the time could probably figure out the timing if they wanted to by parametric testing, but why? But what was listed as his timing curve was not correct! Do they want to build one of their own; if so, Klaus should keep it secret. Do they possess the smarts to make an evaluation of the curve and assess whether it works properly? Well, if so, publish what a correct timing curve should be, and then measure Klaus' and show him what's wrong with his approach!. Why shouldn't a business hold secret those intellectual properties that they feel were the result of lots of work.
    Keep in mind, Klaus has an I/O on the unit which allows the user to change the timing as much as +/-7 deg. if desired; you can use it to come up with your own optimized timing vs MAP and rpm. And on a dual installation, there is a cross-connect which advances one unit when the other is off to regain most of the dual power; you can experience it when you do the pre-takeoff ignition check. The rpm will drop when one ignition is switched off, then climb back up after 1 or 2 seconds! See how your engine performs on just one mag. I've heard several reports of a mag failure causing the engine to overheat on just the remaining mag.
