Yes, it can clear the DTCs (more about this below) I have been beta testing the system for some time now, and have been told I can release some more information. The goal is to provide a useful tool that can be maintained and improved over time.
Here are some other shots and more information about the software.
The OBD2 interface has a 0-5V auxiliary input, user configurable for the input's name (AFR, EGT, or whatever), unit of measure (:1, V, F, etc.) , and can be mapped to the voltage range/slope of the input device,
Here it has been mapped for AFR where 0.0V = 7.35:1, and 5.0V = 22.39:1...
This could just as easily be programmed to display EGT, in units of °F, with 1.00V = 1000° and 2.00V = 2000°.
The software displays selected PIDs (it polls the ECU to see which PIDs are supported, you then select up to 20 to monitor), and will display MPG based on MAF flow and an assumption of 14.68:1 AFR. However if a wideband O2 sensor is connected to the 0-5V input, and the input is named "AFR" then that value will be used in the fuel economy calculation.
The HP estimator uses the weight of the vehicle and acceleration and deceleration times between selected speeds to calculate rwHP and coast down drag HP. The numbers not necessarily be "accurate" (as in "the same") as compared to a dynamometer that directly measures wheel torque--however they are accurately repeatable, allowing performance changes to be determined.
During the test your current speed and a progress bar are shown:
The 0-60 test works similarly:
The available PIDs are read from your car's ECU, you select those you wish to monitor, they will be displayed in the order that you select them:
Active and pending powertrain DTCs are displayed along with their description, possible causes, and diagnostic tips. The codes can be cleared and the SES lamp can be reset with a single click (actually two, as you will be prompted to confirm the action).
All scan activity is logged, log file management is provided:
The first section pf the filename is user configurable, the remainder is the date and time the log was started in the format
yyyymmddhhmmss.
Log files are standard .CSV (Comma Separated Values) format that can be read by any text editor, spreadsheet, or even most word processors. You can then use the tools you like most to analyze the data.
One other neat thing, the application's window is fully re-sizable, even all the way out to full screen, with all of the displayed values growing in size so you can see them while driving!
