1) More Features Added, Cam Analyzer v4.3 B  The Cam Analyzer software can be used "stand alone" to measure cams by hand, or analyze many different of cam files.  It also works with our Cam Test Stand to do precision measurements of camshafts.

In October 2025 we release a major update to our Cam Analyzer, v4.3 B.  Since then we've still been working on it and have even more features, many in the Cam Grinder version.  Listed below are the new features in v4.3 B, and in bold are the features we've added since October 2025:

New Features for All Versions:

  1. You can now flip the drawing of the camshaft on the main screen to now match how you have the cam on the Cam Test Stand.  This makes it easier to keep track of what lobe you are measuring. 
  2. The program has some new Example Cam Layouts, including Ford Godzilla 7.3L, Ford OHC Modular V8, Ford 292/312 Y block, Harley Davidson, and more.
  3. The program will now "talk" to our Engine Log Book Pro v1.1D, so you can pull cam specs from a Cam Analyzer file into the Engine Log Book Pro. 
  4. Greatly improved and simplified method of emailing files, graphs, etc. from the program.

New Features for the Plus Version Only:

  1. A new report type has been added: TDC Lifts, Set Cam Timing to help time the cam you measured in the engine. This report will tell you what intake and exhaust tappet lift to look for at TDC to know how advanced or retarded the cam timing will be.
  2. A new report type has been added: Lobe Analysis - Short similar to the Lobe Analysis report, but with fewer outputs. This report also includes a new output called "Drift Error", and indication of measurement accuracy. 
  3. You can now specify up to 6 lobes for each cylinder.
  4. You can now specify more details when creating a cam profile from .050" inputs, .040" inputs, etc. NOTE: Profiles generated this way are still not precise enough to use for grinding custom cams.
  5. When doing one of the OHC Rocker Arm layouts with the Virtual Follower feature, the program now draws the layout as it appears from the front of the engine for Clockwise and Counter Clockwise rotations.  There is also a new choice of drawing the layout with the valve to the left or right of the cam, so 4 choices total. This will make it much easier to visualize the valve train layout.

New Features for the "Cam Grinder" Version Only:

  1. Now you can edit a cam profile (stretch and/or shrink the lift or duration) from data "Measured w Electronics" directly. This eliminates several steps that were required in previous version, where you had to convert to "Measured by Hand" data, do the edit you wanted, and then convert back to "Measured with Electronics". 
  2. If you click on a section of a report while holding down the Ctrl key, the program presents options for making a small report of the data in that section with a small graph. This lets you quickly see if the data is has any trends, or spot data points which are quite different than the rest. 
  3. You can now generate a 3D.igs file with a particular thickness for the lobe. This will produce a file of 360 1 degree segments up to 3600 0.1 degree segments.  If you need a Solidworks or Mastercam file consisting of arcs, there is an FAQ on our website for doing that.  for that FAQ.
  4. There are several options for Exporting a Manufacturing style file: 
        X,Y
        X,Y,Z
        3D IGS
        Default SolidWorks (may need additional steps in SolidWorks) 
        Default AutoCad (may need additional steps in AutoCad) 
        Default Mastercam (may need additional steps in Mastercam) 
        DXF file 
        G Code file 
        Choosing how many points to be in the file, from 360 up to 3600
        Choosing if the lobe centerline should be put at the exact center (middle) line of the file
  5. When exporting other format files (S96, Comp Cams, etc), you can choose how many points to export from 360 to 3600 and whether to put the lobe centerline at the exact center of the file.
  6. You can create a master cam for a Berco or Van Norman style cam grinder from a cam lobe you have measured.
  7. You can create a cam lobe file from a master cam designed for a Berco or Van Norman style cam grinder if you measure that master cam. This way you can see the cam lobe a particular master cam will produce.
  8. You can assign a different folder for storing your data files. This is typically for a network location so data files can be shared with different computers.
  9. If you import certain file formats (like S96, Cam Dr, etc) and convert this to "Measured with Electronics", the program will ask if you are making a Manufacturing file (like a Berco master cam). If you say yes, it will ask a couple of critical questions to get the file ready for creating a Manufacturing file. This will save you several steps.

If you bought the Cam Analyzer v4.3 B or the v4.3 B update, this is a free update to get these new features.  Simply install right over the top of your current program.  When asked during the installation, select to do a Refresh installation, and NOT a Complete (typical) installation.

 

If you own the older Cam Analyzer v4.3 A now, the update costs are $150 for the std Cam Analyzer for our Cam Test Stand, $200 for the Cam Analyzer Plus, and $350 for the Cam Analyzer "Cam Grinder" version.
