1) Cam Analyzer v4.3 B Released  We've added many new features to our Cam Analyzer software, and are now releasing v4.3 B.  It has many enhancements, some of which include:

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.

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.  If you need a Solidworks or Mastercam file consisting of arcs, there is an FAQ on our website for doing that.  for that FAQ.
