The data is in the following format
instant mpg, instant mph, instant.injHius, instant.injPulses, instant.vssPulses

000.00,000.00,000.00,000.00,000.00

It uses the display formatter and mpg/mph will be to two decimal places if under 99.995. The other values will be 000.00 if zero, or the actual integer number.

With this basic info, a laptop application can compute instant gph and apply a vsspulses/mile and us/gallon correction factor and keep track of accumulated distances, fuel usage. It gets sent out the serial port once per 1/2 second.

I'm not sure about connectivity in vb, it should just be a serial port if you have the ftdi driver installed, same one you connect to from the arduino ide for uploadign sketches.
