In Motec, is a positive damper velocity compression or rebound? A setup
guide says it is compression. But wouldnt the damper position be rising
therefore be rebounding ?
Compression - if you set up a template in Motec that shows damper position,
velocity and ride height on the same page it's easy to see when the
suspension is compressing and rebounding.
Which now that you mention it, happens a LOT in GTR; one of my primary
peeves with it. The incessant bouncing seems a bit overdone imho, and
looking at the damper velocities in spots is suggestive of some oscillation
going on in the physics. I wonder if that's the reason for the staccato
nature of the grip, with the tires constantly chattering over what should be
pretty smooth pavement. For example, in the Fagne esses during a Spa race
recently, there seemed to be nearly no grip there after a number of laps -
like being on ice for a short stretch. Wasn't the tires going away since
they were OK elsewhere, so I figured maybe it was the "live track" thing at
work, maybe simulating marble buildup through there. Looking at telemetry
taken with the sampling rate maxed out for a clue as to what was happening,
it was obvious the suspension was just going nuts through there. Super-high
damper velocities and damper position varying plus/minus about 5cm every
hundredth of a second or so - hard to imagine that being correct. Dunno
what's going on there - if it was "live track" at work, maybe it just
modifies the bump amplitude & frequency for a track section. They already
seem to have chosen a pretty bumpy surface to begin with judging from Spa in
the demo.
Hmmmmm......
