airhead Ignition Control Unit ( ICU)

My G/S runs with an ICU different than the stock one.I think bike previous owner changed it. I ve searched that what is it? İt is russian car Lada's igniton control unit????.I've found specs of this unit. (3620.3734)

Range of operating temperatures, С
-40 .. +85

Nominal supply voltage, V

Permissible limits of supply voltage, V
6,0 .. 18,0

Range of an uninterrupted spark formation, rpm of the crankshaft of the 4-cycle 4-cylinder engine
20 .. 7000

Commutating current, А
7,5 0,2

Time of a sparkless cutoff of a collector current, sec
1 .. 2

Maximum allowable influence of the increased supply voltage up to 5 min. at the spark formation frequence more than 200 Hz (6000 rpm of the crankshaft of the 4-cycle 4-cylinder engine), V

Maximum allowable pulse overvoltages of a positive and negative polarity, V

And schematics is there :

I wonder is this unit suitable for an airhead ?
I am planing to convert my g/s to twin spark.I ve already drilled the heads and and searching for second ICU and coil.
This unit is very easy to get and cheap (10$). Can I use this unit or is it better to get stock black ones?
