I would really like the engine telemetry / info that Vessel View provides. I know there are also other bluetooth gateways. What I have not yet figured out is whether VV or any of these work with my '99 Doral 270 SC with a single 7.4 MPI. I don't want to switch out or add wired backbone. I simply want to use a bluetooth tablet or phone as an MFD at this point. It seems much more economical even though it is a bit limited. I appreciate any advice and input.
