That's kinda what got me on this project with the diesel. Needed the ECM to know when I was floating around "docking" or cruising down the river. Plus I have a couple J1939 CAN display units in the dash monitoring all the important pids, speed is up on there. Also allows ya calculate the MPG off the factory DIC settings. [Dmax averages about 5.5mpg in a 5000lb boat at 50mph]. And last, I'm thinking about adding some cruise control buttons to the steering wheel.


The LS1 guys I spoke with also needed to control off idle fuel and timing tables. Guess those run pretty crappy without knowing your moving..
