Dave W may have the cheap solution, especially when speed accuracy is not an issue.

The marine application I've been thinking about is using TBI PCM 16197427, which is 2000 PPM. The DD does support 2000 PPM. The TBI PCM does not need a VSS to be very accurate. The TBI PCM has near idle / off idle transition at about 3 MPH. I was thinking that the "plane" transition would be good place to switch from near idle / off idle fuel and spark tables.
