Custom OBD-II Monitoring Screenshots
I recently made some updates to my OBD-II driver for LabVIEW. My driver supports PassThru (J2534-1) vehicle interfaces for all OBD protocols including CAN, J1850, ISO9141, and ISO14230.
I write a sample program that monitors accelerator pedal position and graphs RPM. Notice how my crappy truck nearly stalled after going WOT:
It's pretty easy to program LabVIEW. You drag-and-drop icons that represent the various functions. For my 2001 Ranger I select J1850PWM, then connect the icons to read different paramters from the vehicle. Here's the "source code" for the example above:
I've posted this LabVIEW PassThru (J2534) OBD-II driver free on my company's website. You would also need the LabVIEW software which is pretty expensive, but you might be able to buy a student copy much cheaper if you're at a university?
I've also written a 0-60 and quarter-mile program. I'm going to write some more CarPC examples, and I'll post screenshots to keep you guys updated.
