Obviously an excellent feature in this case would be a battery monitor that would shut down the OBDPro completly before you drained your car battery for people like myself who plan to make it a permanent installation.

Good idea will look into this as an enhancement.

It may be overkill though and will just add to your BOM cost.

The ELM327 only draws 9ma. Given that we're talking about a car battery that has (on the average) 600 amp hours of capacity, a 9ma draw will take MONTHS to drain it.

The keep-alive in the car stereo probably draws more - and the ECU, and the keep-alive in the clock...

600Ah??? Are you running on nuclear fuel??

Maybe you added a 0!

BTW, a 60 AH car battery with ONLY an ELM connected will last (IN THEORY) 416 days... No one will care. If you are really concerned about current consumption, you can add AT commands to put the interface into sleep and to wake up, obviously programs must add this feature... or simply add the possibility to wire a "sense" cable that turns on the interface only when the pc is powered up/connected.... just my 2 cents!

whoops... yeah I did.

Good point guys about the battery. Will still measure the current draw once installed just in case.

Quick question, does the usb interface require a usb 2.0 port, or will 1.1 suffice. I imagine 1.1 will be more then sufficient.

It's a 2.0 full speed chipset but backwards compatible with 1.1.

Hey Michbound,

Can you give me a list of all the different reading that I can get with this tool ? Even though I'm in for the beta testing, I'm still I newbie at this.

The params that you'll be able to read will vary from car to car. It's up to the implementer on the car side to determine what will be exposed. You can expect "common" things like water temp and RPM, probably things like fuel trims and air flow, and what everyone likes to hear about - the CEL (Check Engine Light) codes! And yes, you could expect to be able to reset (clear) a CEL as well.
