    OBD Diagnostics connected all the time?

    Hi Everyone,

    After searching here a long time, I ordered the OBD Diagnostics BR-3, and I got the following email response. I'm very happy that Bev is being very forthcoming about the product and doesn't want to ship me something I'll be dissapointed with, but I'm curious if you guys think she's being overly conservative.

    I suspect that many of you use the device exactly as I have planned, and I was wondering if any of you have experienced what Bev describes below.

    Thanks,

    Rob




    Hi Robert, What we have is mostly designed as a simple diagnostic tool, it
    doesn't have a watchdog timer or any sort of automatic operations, so it may
    not be suitable for what you need. For example, it may loose connection when
    cranking an engine, especially if the battery is low, weak, or weather very
    cold, and the only way to reset it is to unplug it and start over.

    I'll put your order on hold until I hear from you and there will be no problem
    to cancel it if you need to.

    Thanks,

    Bev

    It won't help you measure the miles per gallon.

    And again, leaving it plugged in may work, but it also may need to be reset
    and the only way to do that is to unplug it and start over. It is possible for
    transients or other electrical disturbances to cause it to loose connection on
    some vehicles, especially while cranking the engine.

    I can't really reccomend anything for you because I've not used anything else.
    Sorry I can't be much help.

    I have a BR-3, leave it plugged in all the time, no problem. Only time I had to unplug it was after a dead battery, it acted funky.

    Cool! Thanks Chairboy. I guess I'll tell her to go ahead and send it.

    Everyone else have the same experience?

    Same here... I have had my BR-3 connect for over a month now. No problems at all.

    I just wish there was a way to set defaults on the application. You have to select the interface, turn on each sensor, select analog gauges, and then maximize each time.

    crash893 - u could to to a bone yard and snip a connector out and wire it to your harness above the factory plug so the obd2 isn't in your way. You could also hard wire it to your factory wire harness above the connector if the bone yard is inconvenient.

    yea i was thinking about it

    it only uses like 3-4 wires ( of the total of 16 pins) so i could just splice them in
