Electronic throttle lock

[Carter]

Has anyone ever tried programming some sort of throttle position lock to use as a more fuel efficient cruise control? You would deactivate it with brake pressure or clutch engagement like a normal cruise control would but it would let your speed increase and decrease with load just the same as holding the foot feed still. Or, maybe set a specific boost pressure to not exceed and the program would back the throttle out and let the speed decrease or increase as boost pressure would allow. Maybe this topic has been hashed out before but I haven’t run across it on this forum yet.
