Fixing Bus Error and gauge freeze for Power Vision PV-1

We’ve seen certain Dynojet Power Vision PV-1 equipped J1850 bikes experience a “Bus Error” on their odometer. In some cases, this may cause security to shut the bike off upon start up. We have also seen some bikes experience gauges cutting out and difficulty while using the Autotune function of the Power Vision. This only occurs when the Power Vision is plugged in and only a few bikes appear to be affected.

To remedy this, Dynojet has implemented firmware that’s “activated” by entering in a code on the Power Vision. Follow the steps below if you’re experiencing any of the issues we listed above.

How to Prevent BUS ERR, Gauge Dropping, & Autotune Unresponsiveness

  1. Connect Power Vision to motorcycle with key and kill switch in the “On” position.
  2. Select “Settings” > “Enter Code”.
  3. Type in the code “1851” then press “Save”.

Your Power Vision is now in Legacy mode! If for any reason you need to disable Legacy mode, you can do so by following the same steps but using the code “1850”.
