Tim:
You are correct. I use an LVDT to measure throttle position and originally thought about using them to measure axle movement. But LVDT?s are expensive and you need four of them. Chuck?s idea to use LIDAR tech to measure lift and compression could also be used to measure axle movement. We talked about that but once again, I did not want to overdrive my headlights here. If the lift sensor works, it will be applied elsewhere on the car.
