Default Koso Guages with power vision

I have the PV2b and the digital gauges on my 13 road glide, the only way to auto tune and for the power vision to read the ecm is to unplug the spedometer and tac, does anyone know a work around for this? I contacted dyno jet and Koso they blamed the other. Thanks in advance.

It does not work, you have to use one or the other.

NO the Koso and other aftermarket gauges do not comply with the bikes electrical system. Same goes for aftermarket Radio's and amplifiers. There are basic commands that these aftermarket parts do not comply with and that is an issue.
