DynoSim 6 and Dynomation 6 engine simulation software is out now. I have the DynoSim 5, but Motion Software did not have an upgrade path for DynoSim 5 to Dynomation 6. They had the usual 5 to 6 within the same software, but I wanted to step up to the better software Dynomation 6. I sent a email to Motion Software and asked about upgrading to Dynomation 6. I got an email back from Larry Atherton saying that I could get a $100 off the regular price of $499.95. You might know his name, he has authored several books. I asked about this being available for others and he agreed to the same price for others thru the end of this year. So if you have DynoSim 5 and want to upgrade to Dynomation 6, you can get it for $399.95 if you act before the end of this year. To get the special price you will need to contact Larry Atherton at the email address below. I asked Mr Atherton about using an asymmetrical cam lobe and he responded ...... You can model asymmetric lobe profiles. That is, if you import a lobe-profile file that models an asymmetric lobe, that model will be used by Dynomation6. However, if you use 10-point cam timing place to model asymmetric 10-point cam file, also. That will be “activated” in a future (free) upgrade. firstname.lastname@example.org http://www.motionsoftware.com/Dynomation6.htm This video is Dynomation 5, but you will get some sense of it's capabilities.
