1) Featured Product: Fuel Economy Calculator This software will calculate MPG (miles per gallon) improvements for various modifications to the engine, vehicle, road, or driving conditions. It can answer questions like:
The Fuel Economy Calculator is probably the most
detailed program for predicting the effects of modifications on steady state,
cruising fuel efficiency. (It does not estimate effects on stop and
go driving, or driving through some type of accelerating and braking
cycle.) It includes these
features:
Calculates cruising MPG for most any MPH or RPM (user selectable) for most any transmission gear.
Built in examples of several transmissions and vehicle aerodynamics to make building vehicles easy.
Built in examples of complete vehicles.
Easily build engines for the program by choosing one of the "Typical" Engine Types. Then all you need to supply is Displacement and Number of Cylinders. Switch to one of the "User Defined" Engine Types and make most any engine modification you want.
Side-by-Side comparison of a Baseline vehicle to a proposed New vehicle.
Detailed enough for engineers to estimate effects, but easy to use features so most anyone can use it. The engineering details include:
Defining air resistance (aerodynamic drag) as Drag Coefficient and Frontal Area.
Defining rolling resistance by simple general tire descriptions or by entering Rolling Resistance Coefficient (RRC) directly by right clicking on the Tires label.
Generates tables of MPG over a range of either RPM or MPH (user selectable) for each transmission gear.
High resolution graphs of the results in the Table are possible with advanced cursor, zoom, scaling and print features let you do detailed analysis.
Auto-Links to our latest Engine Analyzer programs for automatic readings of how engine modifications are likely to affect Fuel Economy.
Will accept power curves and engine specs automatically sent from our latest Engine Analyzer programs.
Option of Perfect Lab or Real World Driving Conditions adjusts for results more in line with actual cruising Fuel Economy users would expect.

2) Christmas Is Coming Just a reminder that Christmas will be
here in just a few weeks. If you've been thinking of getting one of our
products, put it on your Christmas list. 
Maybe Santa will be extra good to you this year (as long as you've been nice
).
for some ideas of what to ask for, starting at $49.95 for our Compression Ratio
Calculator, Transmission Gear
Calculator, Fuel Injector Calculator and other
computer programs. Or maybe get an update or upgrade to something you
already own.
Software can be "email shipped" almost up to Christmas Day. However, anything that requires UPS shipping should be ordered by Dec 16 to ensure Christmas delivery. For last minute shopping ideas, visit our website. All software products have a shopping cart option and can be ordered on line.
