You have my curiosity up.
Are you looking for port data from a sample engine?
Just port window size data, or discharge vectors? Maybe port cross section data?

Dynomation Simulation program is for 4 strokes is that what you are working with ?
If you want info on 2 strokes port time area map in link below press "Theory" button and go to section 4. for some details on time area:

You might have seen this? Also 2 stroke port timing info here by Gordon Jennings page 76 in the book 86 in the scan list:

There is a 2-stroke version of Dynomation sold by motionsoftware.

Since Modifiedoutboard asked "

Sounds like he needs a port time or port area map for the program? Doesn't the program do that?
They are derivable with port measurements, crank degrees and piston position and rpm.

I haven't seen a complete port map ever posted here and wondered if nyone really has a clue as to what one liiks like. OEMs use dynomation two-stroke to design new engines. I wrote excel spreadsheet to calculate timing heights and effective area of ports. Just wonder who has ever gone behind the liner on this forum...……..
Dynomation requires the input of the cross sectional area of the intake and exhaust system at various locations in the port, along with their port lenghts, the crankcase compression ratio, and the dimensional details of the engine...bore, stroke, event timing, etc.
From there it calculates all of the flow/velocity numbers through the specified rpm ranges. As described above...all this number crunching takes a bit of time.
The end results is information about the engine as it progresses through the rpm range.
It is a lot of information for the user to digest and make decisions from.
In the end it only gives you data on the parameters entered. It will not design an engine for you.
That said, it is a very powerful tool in capable hands.
