Earl, I have in my scrapbox a Vlach ignition, serial 25456, type EZM 1 Ti.
These ignitions do have a data output where you can read rpm and timing, as well as operating hours using a data terminal. No LED on these buggers.
The ignition is an advancer, that calculates when to fire due to engine "history", I believe last 10 rpm or so. For starting, the timing is late. The second magnet resets the ignition so it can fire again.
Since the serial number of yours is close to mine, I would suggest they are close in properties, though production for MVVS and Evolution may show large differences.
Do not try to run the engine without a resistor type spark plug. It won't work. It fires OK with a non-resistor plug, but the timing is all over the place; a sure way of getting a fire spitting, backfiring engine.
These ignitions were quite prone to different kinds of failures, though many still work okay by this day, even though discontinued since mid-2006, when they were replaced by MSR-ICU units.
I hope this information is of some help.
