--------------- May 28, 2003
v3.2 A.008 ------------------------------Enhanced the error messages in Auto-Linking to Engine Analyzer v3.2 if
an error had occurred.
Program now looks for both Acrobat and Acrobat Reader to display the
users manual.
Fixed Help in Results and Graph Screen, where Help screen just flashed
and did not stay visible.
More detail in About screen about other products.
Main Screen Help, then Other Products now shows the About screen.
Fixed these bugs:
When opening files, the Preview indicated Manual trans if you had
picked
a file with an EXAMPLE torque converter.
When picking example Tires, new choice was not saved correctly if you
had set the preference to Allow Instant Updating of Results.
Refined the 'Optimize' feature if you chose NOT to use the optimized
converter or axle ratio.
--------------- Apr 22, 2002
v3.2 A.004 ------------------------------Fixed bug where some converter stalls were not being done correctly at
low RPMs
Fixed bug where the AutoLink feature to the new Engine Analyzer v3.2 did
not always transfer a power curve correctly.
--------------- Oct 23, 2002
v3.2 A.002 ------------------------------Fixed bug where Optimizing Torque Converter would not always be enabled.
Fixed bug which could cause problems when Optimizing torque converter or
axle
ratio.
--------------- Oct 23, 2002
v3.2 A.001 ------------------------------Program is now a 32 bit version, fully compatible with newer operating
systems,
starting with Windows, 95, then 98, Me, XP, and 2000. This also allows
you to
use much longer, more descriptive file names for saving vehicles,
throttle stop
data and dial in data. It is also more compatible with newer printers.
The program is now designed for 600 x 800 or higher resolution screens.
There is now a separate “Examples” folder for example vehicle files
provided by
Performance Trends. New vehicles which you save will be saved to a
separate
folder of Your Saved Vehicles.
A new Preference lets you remove the Performance Trends Example Vehicles
from
Your Saved Vehicles if you have updated from Version 3.0.
There are now File commands to save a vehicle file to a floppy disk, or
open a
vehicle file from a floppy disk. This makes it easy to copy a vehicle
file from
one computer to another.
You can now choose to list vehicle, dial in and throttle stop files
alphabetically (as normally done) or by saved date, with the most
recently saved
files listed first. This should make it easier to find recent files more
quickly.
You can now choose to only list vehicle files which have certain words or
phrases in their names, like just “Chev” files, “Import” files or “Race”
files.
This should make it much easier for you to find example vehicles or your
vehicles in a long list.
The user’s manual is now available from inside the program by clicking on
Help
at the top of the main screen, then Display User’s Manual. The manual is
in a
high quality PDF format.
The Performance Trends website is now available from inside the program
by
clicking on Help at the top of the main screen, then Performance Trends
on the
Web.
A Print button and Windows Print Setup button (or menu option) have been
added
to many screens to let you print these individual screens.
An Optimize button has been added at the top of the Main Screen, which
lets you
instantly find the best torque converter (if transmission is an
automatic) or
final drive (rear axle) ratio for quickest ET.
Two new calculation menus have been added, one to convert engine size
from CCs
or Liters to cubic inches, and the other is to estimate the vehicle
weight of
your car based on some popular car models.
The recent results section of the results screen now includes 60 ft time
and the
improvement for the current and previous run.
A summary Time Slip, similar to what you get at the drag strip, is
available in
the results screen for the current results, and available for any of the
25 runs
in the history log.
Commands in the History Log have been updated and streamlined. Now when
you
click on a row in the History Log, you are now presented with 4 command
options,
Open, Rename, Help or Time Slip.
The Dial In and Throttle Stop screens have a new spec of "safety margin",
which
the program uses to give you a margin of error to keep you from breaking
out.
The Throttle Stop Predictions can now be based on just one previous run,
and an
Adjustment Factor from a previous run. This Adjustment Factor is
obtained by
doing a calibration run at some previous time. This is more convenient
method of predicting throttle stops.
The program will now “Auto Link” to our upcoming Engine Analyzers,
versions 3.2.
Auto Linking means the Engine Analyzer screen will show the resulting MPH
and ET
from an engine change, running the Drag Racing Analyzer program
completely in
the background.
A new Preference lets you obtain instant updates of ET, MPH and 60 ft
times from
every change you make in the vehicle specs screens. This can be a great
time
saver, especially on newer, faster computers.
Several new Example Vehicle Files have been added, to make building your
vehicle
easier.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
--------------- March 27, 2002
v3.0 E.001 ------------------------------Program now remembers Comment changes made in comment screen in the
results
screen.
Added ability to do Throttle Stop predictions based on just 1 run.
--------------- Jan 8, 2001
v3.0 D.003 ---------------------------------Added 'Print' button to examples form.
Fixed bug where power curve sent from Engine Analyzer (std, plus
or Pro) would not be corrected to Std Conditions for the case when
the Engine Analyzer was NOT using standard weather conditions and
the Drag Racing Analyzer was set to use SAE Conditions in the
Engine Specs screen.
Added Print button to About form.
--------------- Aug 8, 2000
v3.0 D.002 ---------------------------------Fixed some problems printing Analysis reports. Previously, not all
parts were printed and sometimes blank pages were included in the
printouts.
--------------- July 26, 2000
v3.0 D.001 ---------------------------------Fixed problems when program read engine power curves from Engine
Analyzer programs (Std, Plus or Pro versions). If the power curve has
more than 10 RPMs, the program now picks RPMs to keep which
better represent the entire power curve. 10 RPMs is all that the
Drag Racing Analyzer can hold.
Fixed a problem which occured if you used a "Full Engine Power
Curve" and the engine's torque curve was VERY steep at low RPM
(for example 0 torque at 2000 RPM and 400 ft lbs at 3000 RPM).
For automatic transmissions, this would produce unstable converter
stall RPMs (small change in Conv Capacity produced large change
in Stall RPM). This version reduces this problem and produces more
realistic results.
--------------- Jan 27, 2000
v3.0 c'' ---------------------------------Corrected TqFlite Trans 2nd gear ratio from 1.24 to 1.54 in example specs
Fixed minor bug in the "Match Veh Perf "
Finish Gr = 1.
Vehicle Summary if you said
Corrected Dens Alt and Dry Dens Alt calculations. We were previously not
correcting for temperature affects correctly. This had NO affect on any
performance or dial in predictions. We do NOT use Density Altitude
numbers for any calculations. We just report them for info to the user.
--------------- March 9, 1999
v3.0 b ---------------------------------(Click on Help, then About at the top of the Main Menu for the version #)
Bug corrected when doing Opt Shift if you specified Peak Tq
RPM was the same as the Peak HP RPM.
Bug corrected where printout was not correct if you picked
an example Torque Converter.
Corrected example TH350 gear ratios from 2.48 and 1.48 to 2.52 and 1.52.
Bug corrected when previewing Vehicle files, the peak HP and peak HP RPM
were swapped. The files were opened correctly, just preview was wrong.
Disabled printing History Log if History Log is not displayed.
---------------
May 7, 1998
v3.0'
-----------------------------------
Added "300
Sand Drags (100 yds) " as a possible Track Length
for a race in the Calculate Performance Conditions menu.
