DashHawk Frequently Asked Questions

What vehicles are supported by DashHawk?

Many Ford, Chyrsler, and GM vehicles started implementing Controller Area Network (CAN) communications in 2004.  As new vehicles are introduced, most are CAN compliant.  As a result, you have some vehilces in 2004, many more in 2005-2006, most 2007s, and finally by 2008 ALL vehicles sold in the US must be CAN compliant. A matrix for known supported vehicles is shown in the application guide page.

How big is DashHawk?

It is a remarkably small device for all the power it packs!  It is 1 7/8" tall by 4" wide by 3/4" thick.  It EASILY fits in a pocket and is smaller than many cellphones!

How many parameters can I view at once?

You have many customizable display options. You can view up to seven parameters on one display (plus fuel system status and display number). There are 11 customizable displays. A list of supported parameters can be found on the "More Details" page.

Can I change how the data is displayed?

Certainly! Just press the MENU button and then select SetUp->Display->Display X (where X=the number of the display). You can choose 2 function bar graph, 2 function digital, 3 function digital, 4 function digital, 6 function digital or 7 function digital formats.

How do I know what's "Normal" for my car?

Every vehicle is a little different, especially when some are fueled by diesel or have a turbo/supercharger. However, the User Guide has a complete set of descriptions for all the parameters in the Parameter Reference section. Be sure to read it! Also, look for a Firmware download in the near future that will have some display markers for normal ranges of the more common parameters.

Is there any type of data capture?

Absolutely! DashHawk has a built in Data Logger feature that allows you to pick up to 5 parameters to record for up to 3 - 5 minutes (record time is vehicle dependent). You can review the data step by step on the DashHawk or hook it up to your PC (via the included USB cable) and analyze the data with the included PC sofware.

In addition, the 0-60 MPH and Quarter Mile tests also record addition data that can be reviewed on the PC.

How do I find documentation for all the features?

The documentation can be found in several places:

• On the original CD
• On this web site's Downloads page
• Installed in the Program Files->DashHawk->Documents folder when you installed the PC software
• Online HELP is available at any time in the PC Software by hitting F1

How do I use DashHawk to increase my fuel economy?

Fuel economy boils down to driving style and operating the vehicle in the best efficiency range. To do that, here are some general tips:

• Use DashHawk to monitor engine Load and engine Absolute Load. Keeping this number low in a cruising configuration will reduce fuel consumption.
• Monitor TPS and Speed. It may sound obvious, but keeping a light foot and operating in a speed appropriate for the gearing and torque curve of the vehicle are key factors in reducing fuel consumption.
• Change up to a higher gear whenever possible (in a manual car). Keeping the RPMs down without lugging the engine can help efficiency.
• Use the MAP parameter in conjunction with TPS, Speed, Load, and MAF to monitor your driving style to minimize fuel consumption.

How accurate is the quarter mile time?

Experience has shown that a variance of 0.1 -0.2 seconds from calibrated dragstrip clocks. This can be greatly affected by wheel spin, crosswinds, etc. but is a useful relative gauge to compare modifications and conditions.

Can I use the quarter mile time to figure horsepower?

You can use the Horsepower Calculator in conjunction with the Quarter Mile measurements to get a good idea of your horsepower at the wheels and crank.
