Controlled Induction 2020 is our latest, most versatile and accurate cam design software.  It combines, replaces and succeeds all of our previous software.  Beyond calculating your given engine's cam design requirements, this software will generate, and save to file, the cam profile lift tables.  These files can be used in Engine Analyzer Pro and Dynomation software to simulate, and verify, each cam design's performance.  You can also have Howards Cams CNC grind these profiles on the cam core of your choice, using these same lift table files. ​​


Controlled Induction 2020 Version 3.02 accurately models 1 to 12-cylinder engines with cylinders from .7854 cubic inch (1.000" bore and stroke) to 169.646 cubic inches (6.000" bore and stroke)

You can select and load the bore, stroke and rod length from our engine library of hundreds of short blocks. 
The Cam Profile Generation feature will generate and check that each profile's velocities, accelerations, nose radius and negative radius of curvature meets all design requirements and make minor profile design adjustments, if required.  If these adjustments will not satisfy the design requirements, a message box will appear with simple instructions on how to remedy the design faults.

Cam Profiles are Saved to File in a S96 File Format That Can Be Loaded into Engine Analyzer Pro or Dynomation software.
The Software Can Make All Decisions when operated in Auto-Calc Mode.

What Is Being Calculated, Why and How, Are Explained In 44 pages of the User’s Manual, Along with Simple Instructions

Camshaft Design & Profile Generation Software

Controlled Induction 2020 version 3.02 does so much more than calculate an engine's camshaft requirements, it is one of the best engine development tools available.  If you don't understand how the parameters in the engine are related and how they affect each other, this software can teach you.  It can help the ignorant, but can't fix stupid.
