Any thoughts? I'm almost inclined to think it's something with the tach reader but I wanted to get other's input as well.

John, when time permits, I'd be interested in the following two experiments which shouldn't take long. Run engine under load:

1. in conventional at 8 sMPH or thereabouts - probably around 10V or so. Is the surging behavior any different?

2. in DCS at 8 sMPH. Lower track voltage to 12V or so. Then up to 18V or so. Does surging behavior change?

This is simply an attempt to further slice the pie.
