Thought I'd throw together a list of vendors that provide Diagnostic software for our trucks.

ScangaugeII This is actually a computer that uses the OBD port on your truck to provide you with not only the ability to see and clear codes which turn on your check engine light (SES) but also gives you digital gauges and a trip meter. The display can be mounted just about anywhere and doesn't take up a lot of room.

ProScan

Freeze Frame Data
The new Freeze Frame tool allows you to read any freeze frame data stored on your vehicle. Freeze frame data represent a snapshot of critical sensors at the time of a detected problem (thrown diagnostic trouble code). Now you'll be able to know how your vehicle was being driven when the trouble code was thrown!

Oxygen Sensor Tests
The new Oxygen Sensor tool allows you to view tests that your vehicle performs on each individual oxygen sensor. If you're having problems, this tool will allow you determine if your oxygen sensors are to blame, and if so, which one!

Diagnostic Report Generator
With ProScan 4.0, you can generate a comprehensive diagnostic report for a vehicle with a single mouse click! You can provide your company information along with your client's details, and ProScan will quickly generate a printable and professional report for your client!

ProScan will provide you with a list of every DTC stored on your vehicle along with a detailed description to help you pinpoint the problem.

Your very own digital scope!

Why pay thousands for a sophisticated oscilloscope when you can use ProScan to plot every sensor on your vehicle?

Select up to 4 sensors to monitor in real-time. For each sensor, you have the option of English or Metric units as well as the type of chart to use (line/bar/dot).

Your very own virtual drag strip!
The virtual drag strip is another great reason for performance enthusiasts to own a ProScan device.

Simply stop your car on an open road, hit the Stage button, launch whenever you're ready, and continue to accelerate until the timeslip is complete!

ProScan will accurately calculate the following information for your timeslip:

60 Foot Time

0 - 60 MPH Time

1/8 Mile Time and Speed

1000 Foot Time

1/4 Mile Time and Speed

Timeslips can even be printed or saved to file!



Your very own dynamometer!
If you were thinking that no other feature could possibly top the virtual drag strip... you were wrong!

With minimal information about your vehicle, ProScan can produce consistent and reliable horsepower and torque curves!

Not only can you print or save a dyno session to file, but you can generate a JPEG image of your dyno chart to share with your friends online!

plus much more.
