What would cause an error with "straight line" steering input but not free/locked?

Jonathan Corno
error part 2
error part 1
When I run a straight line acceleration event using free or locked steering input, the event runs and the car performs as expected, but when I run the same event using straight line steering input, the event errors

    I checked that turning the steering wheel a positive angle turns it left, and the wheels also go left so that seems correct,
     
    I had a gear ratio of 6.614 for 360 degrees of steering wheel rotation to achieve 0.95 inches of rack displacement, but for some reason when I ran a step steer event, the event would fail unless I raised the ratio significantly. I correspondingly increased the steering wheel angle and the event would run as expected, but straight line steering is still erroring.
