Describe the bug
tractionAdvanceDrop does not update if VehicleSpeed stays static but AuxSpeed1 updates

Hardware

Board: f767 nucleo
Engine info : dual arduino uno generating wheel speed

To Reproduce
Steps to reproduce the behavior:

Hook up two pulse generators to inputs, configure them as VSS and AuxSpeed1
set up traction control table as:
output wheel slip, vss, auxspeed1, and tractionAdvanceDrop
Vary vehicleSpeed to impact slip, watch tractionAdvanceDrop change
vary auxspeed1 to impact slip, watch tractionAdvanceDrop not update
end up in a ditch cause trac didn't work

Expected behavior
auxSpeed1 to update tractionAdvanceDrop and apply to timing advance
