Fixed bug where Port Flow Analyzer files may not be imported correctly if the data was in Metric units.
Made the simulation of very high pressure drops across restrictors more accurate when for severely restricted motors.
Fixed bug where the flag for identifying Fuel Type setting in v3.9 could be lost during calculations. This caused files you saved (or saved to
History Log) could have the Fuel Type or Fuel Richness to change.
Added a check for the "Fuel Type" bug discussed above to have the program correctly open the correct Fuel Type and Fuel Richness in saved files.
Added 'Help' button in screen to pick RPMs for Cycle Graphs ("PicRPM" option at top right in Graph screen).

----------- v3.9 A.055 Nov 19, 2012 ---------------------------------
Fixed minor bug where 2 future Enterprise Edition features were shown but did not do anything.
----------- v3.9 A.054 Nov 18, 2012 ---------------------------------
Released several features in the new Enterprise Edition:
You can use a full compressor map to define the performance of a turbocharger compressor.

You can specify a particular turbocharger boost level, intake manifold temperature (after the turbocharger compressor), and exhaust backpressure level. This gives you more freedom to simulate some particular situation which may be difficult to simulate using the turbocharger compressor and turbine model specs in the program.
You can view the compressor map when calculations are being performed to see what area of the map is being used.
You can use a full compressor map to define the performance of a centrifugal supercharger compressor.
You can design a system where a centrifugal supercharger feeds into a roots blower supercharger.
You can interface to the Compression Ratio Calculator program and transfer data back and forth between them.
You can run a part throttle performance “map”. This map can be useful for calibrating electronic engine controllers, or just understanding part throttle performance.
There is a new Preference which lets you choose a different language for certain labels in the program.
Two new Preferences are provided to adjust the valve train dynamics calculations. One allows you to increase the stiffness of the lifter/cam interface. The other allows you to increase the stiffness of the rocker arm for Overhead Rocker Arm styles of valve trains. The factor you pick is multiplied by the default stiffness. For example, if you pick 1.5, the default stiffness is increased 50%.
A Preference has been added to allow for adjusting intake runner wall friction for the Intake Runner and Port. The program picks a certain amount of wall friction based on manifold type, Runner Flow Coef, etc.
Your choice here will change it by the percentage you pick.
A Preference has been added to let you adjust how much valve toss
(separation between follower and cam) will be called Valve Toss in the tabular results. The default used by the program for many years is .020”. If the program sees more than .020” separation between cam lobe and follower, it is flagged as Valve Toss in the calculated results. Your choices will let you pick a certain percentage of the lobe’s maximum lift.

The form to Search (seek) a program for communicating with the
Engine Analyzer Pro is now faster, looking in the default location first.
----------- v3.9 A.041 Jan 29, 2011 ---------------------------------
Fixed bug where the program's estimate of where Lifter Pumpup occures in the RPM range was not always done the same. This was for situations where you were using a Cam File for the intake lobe, AND had Valve Train
Dynamics turned OFF. This was a pretty limited situation.
Made a Progress Bar for sorting through Chain Calculation results, which can be very time consuming for a large number of Chain Combos.
Enlarged the form for picking which saved results to Retrieve from Past
Saved Tests.

Program now accepts a negative Combustion Chamber volume, as used in some Diesel Heads.
Program now warns if a Cam File has MORE than 390 deg duration at .050" lift and problem with file is it is likely in CRANK degrees, not CAM degrees.
Fixed bug which v3.9 A.038 tried to fix where the method used to divide up the intake port and runner into various segments was not ideal.
The v3.9 A.038 fix was also not ideal and just moved the problem to show up in different scenarios. The new "fix" in A.040 should be a more
"universal" fix for all scenarios.
Made program more forgiving at reading S96 and Comp Cam format cam files.
Added "Example Comp Cams Format File.txt" to CamFiles folder as an example of a Comp Cams format cam file.
Made a Note about Runner Flow Coef. in the Intake Specs screen to show a
'Typical' range for the particular Manifold Type you selected. Also, the

Help Definition for this has been expanded to better explain this critical input.
----------- v3.9 A.038 Sept 22, 2010 ---------------------------------
Minor change. Program now has larger "Help" box to explaing Intake
System
Specs.
Check Boxes for various Restrictions now have popup explaining how to turn them on or off.
Removed the warning added in v3.9 A.022 about the program not simulating
Intake Restrictors correctly. The program WAS and still DOES simulate the restrictors correctly, as always before the turbo or centrifugal SC compressor even if the you have specifed a Blow Through turbo (where the throttle body appears AFTER the compressor).
Added 'tooltiptext' explanation 'popups' to Assymetry inputs showing calculated centerline of Peak Lift, based on std Centerline (based on opening and closing events) and the Assymetry input.
Added 'ATDC' and 'BTDC' labels to the Centerline inputs in the Cam
Specs screen.
Fixed bug where the number of tuning elements the intake runner and port were divided up into "behind the scenes" in the calculations was not done as well as possible. The result was a minor change in port or runner dimensions could make significant changes in results. The problem was most notable with fairly short, but large diameter intake port specs, those not typically encountered in most engines. This situation was also typically not close to optimum specs for performance.
----------- v3.9 A.036 June 16, 2010 ---------------------------------
Fixed some bugs for picking a file from the Cam Analyzer. This process was working at one time, so we must have reintroduced some older code into a part of the program inadvertantly.
----------- v3.9 A.035 May 12, 2010 ---------------------------------
Now long runners with very good Int Runner Flow Coefs (which are actually highly unlikely to be possible with real parts) will be more accurately simulated.

Fixed a bug where program could 'double convert' english files from the std or Plus Engine Analyzer to Metric units, producing errors in the conversion to millimeters.
Program can now open EA v3.4 files.
Fixed some minor bugs when printing a worksheet and emailing it.
Fixed minor bug where the "See Layout" screen was not drawn correctly for 2 or 3 ports per cylinder.
Fixed some bugs where the Head Flow Table would not get updated correctly for Flow Coef when you changed the test pressure and were doing Metric units. This did not affect performance calculations.
Program now checks the VVT specs before doing calculations to make sure there are no major errors in the inputs.
When files are converted from English to Metric and vice versa, the program now also converts the VVT specs as needed.
----------- v3.9 A.027 Mar 15, 2010 ---------------------------------
Program now checks when opening a saved Cam/Valve Train file which was saved in an earlier (than v3.9) version to see if new input specs are correct, like Assymetry, etc.
----------- v3.9 A.026 Mar 10, 2010 ---------------------------------
Added option for Ascii Files to export Cycle Data in 1 degree increments.
This is done by linear interpolation between the typical 4 degree increments.
Fixed a bug where program could bomb if you tried to print a Spring Table in Valve Train Dynamics screen if certain inputs were blank.

Millimeter measurements.
----------- v3.9 A.025 Feb 21, 2010 ---------------------------------
Fixed bug where Chain Calculations would not display correct results if you had selected Metric Units.
Chain Calculations now show "Nm" and/or "Kw" if you selected those
Metric Units.
----------- v3.9 A.024 Feb 20, 2010 ---------------------------------
Fixed bug where the Chain Parameters at the top of the Chain Results grid page was moved too low and covered the RPM row of the results.

----------- v3.9 A.023 Feb 19, 2010 ---------------------------------
Fixed bug for entering valve lift numbers in the Flow Table in mm (Preference introduced in v3.9 A.022), where it was still using the upper limit of 3 inches. This limit is now 80 mm for lift in mm.
Added some notes when changing Units in Preferences under the
"Calculations, cont" tab that when you "Pick" certain outputs to be Metric or English from a list, that the list is NOT updated until you click on OK to keep the Preference changes.
----------- v3.9 A.022 Feb 13, 2010 ---------------------------------
Program now warns you if you are running an intake Restrictor (for restricted classes of racing) and a Turbo or Centrifugal Supercharger that you should specify the throttle location as 'Draw Through' to properly simulate the restrictor's effect. (The restrictor is almost always before the turbo or supercharger, even if the throttle may be after the turbo or supercharger.
Fixed bug where the cam profile Ramp Rating was not being done as precisely as it could be for Seat Timing. Now the Ramp Rating is adjusted based on the Preference Setting of what you want to call seated valve lift, either .003 or .000 inches.
Program has a new Preference for the Flow Table for cylinder head flow data, to be able to enter the data in Millimeters and CFM or
Millimeters and LPS (liters per second). Preference is located under
"Calculations" tab.
The process of Adding a User Entered 'Dyno Curve' to the torque and HP graphs has been enhanced. A couple of features (opening and saving a file, and the Check Box on the Dyno Curve screen) were not being done as smoothly as they should have been.
Program can now better handle folders not existing when you do an
Import of old Engine Analzyer Pro files.
----------- v3.9 A.021 Feb 9, 2010 ---------------------------------
Idle Vacuum change for a Roots SC is too small compared to a Cent. SC.
Increased the Pressure Ratio limit for turbos from 3.0 to 5.0.
