  • What is the fastest OBD2 to USB interface?

    I currently have an an elmscan 5, this thing is super slow. I want something that has little or no lag with dashcommand. Ive been looking into the MX however I dont like the fact it is bluetooth, is there a USB interface that is comparable?

    The OBDLink is a very nice tool, and significantly faster than anything else I've found out there (sans MX, can't afford one so I can't say about that).

    Keep in mind, it may be slow in part because of your vehicle. My vehicle only gets 3-4 pids per second, no matter what tool I use, I don't get much faster than that.

      A big part of the delays is probably caused by the cars and also asking for too much data.
      Any other protocol than can is somewhat slow by design.

        Passive listening to can bus (like ATMA) has only bottleneck in current devices... even MX, advertised as fastest so far works at I believe 115 (or 230, don't recall) kbaud max, while can buses in modern vehicles are at 500 kbps and peak at almost 100% utilization. Some manufacturers are introducing secondary and even tertiary buses so I guess bottleneck will shift from vehicles to interfaces that would have to be able to read and transmit data to host with higher speed.
