Motion Driver for iRacing racing sim
A beta version is available
for the racing sim iRacing. The download is on the
Introduction page.
Access to the racing sim telemetry
data is via the sim's shared memory area - there are no plugins
required.
IMPORTANT: this is BETA
software and may contain bugs - please use with care!
Installation:
Installation of the motion driver
is mainly the same as the other versions - see
section 2.
Operation:
The software operation is mainly
as described in Section 3 Operation.
Some of the flight sim related
features such as heave movement recording due to turbulence etc are
not active in the iRacing motion driver for obvious reasons.
The default .bff config files in
the iRacing motion driver zip file contain cue settings better
suited to the faster dynamics of the racing car sim. You may wish to
experiment with them. Generally because the on-ground vehicle accelerations
are held for shorter durations before changing again rapidly there
is less need for washouts in the cue, so the sample configs don't
use acceleration washouts (other than where they are needed for basic cue
development - ie in the heave and yaw cues). The acceleration scaling to fit the cue limits may
also need to be adjusted to suit different vehicles.
NOTE: When iRacing leaves a live driving session
the telemetry data can become erratic and it is best that the motion drive
is not left on Drive when this happens. By default therefore the
drive will switch to Hold at Start Pos mode whenever iRacing reports
that the car is not live on the track.
Remember you can use the Drive
and Hold hot-keys or hot-buttons which are defined in your .bff cue
configuration file.
The refresh rate of the motion
driver output can be increased up to the data refresh rate of the
iRacing telemetry data output using .bff configuration file
parameter MD_Delay.
Use with Fullscreen Mode:
iRacing needs to be started before
the motion driver - in order to allow the software to find and
interrogate the iRacing shared memory at startup. If you normally
drive iRacing in fullscreen mode then try the following...
-
Open your motion driver .bff
config file and set Drive and Hold hotbuttons or keys.
-
Start iRacing in fullscreen
mode then hit Alt+Tab to minimise the iRacing window.
-
Start the motion driver and
select your config file etc - check that the software is running
and displaying the iRacing sim time etc to confirm it is reading
the telemetry.
-
Click on iRacing in the task
bar to return it to fullscreen. Then use the hot buttons or key
to hold/drive the motion driver output as required.
-
When finished Alt-Tab will
minimise iRacing again and allow you to inspect/close the motion
driver as required.
When you are setting up and tuning
the motion driver it is probably best to run iRacing in windowed
mode so you can see what is going on better.... Then switch to
fullscreen mode when you are familiar with the software and its
operation.
If you find any bugs or strange
behaviours in the beta version then please let me know.
