CONNECTION AND INSTALLATION
If attaching to a simulation racing rig / seat then please allow for a maximum depth of 10mm with the M6 bolts that you use. Note the thickness of the plate / platform that you’re attaching the pedals to, add that to 10mm and you will then know the length of M6 bolt that you need to use. Due to the standard sizes of M6 bolt lengths you may need to use washers to prevent longer bolts from encroaching too far inside the pedal unit when attaching it to your rig. You only need to hand tighten – do not use power tools to tighten the bolts.
ADJUSTING PEDAL SPACING
Use the included allen key to loosen the two bolts on the underside of the pedal set and then slide the module until you have the desired spacing between each of the pedal modules. Tighten all bolts to ensure that all of the pedal modules are securely in place and won’t move during a race.
ADJUSTING PEDAL FACES
The pedal faces can also be adjusted to fine tune the spacing between the
pedal faces, as well as the height of the pedal face on the pedal arm. The
Clutch and Brake pedal faces can be adjusted horizontally and vertically using
the holes provided. The Gas pedal can be adjusted vertically.
Loosen the two bolts in the pedal face. Remove the bolts, reposition the pedal
face in the desired position and then reinsert and secure the bolts.
ADJUSTING PEDAL SPRING FORCE
All of the pedals can have different levels of spring force applied, using the
springs (Gas and Clutch) and elastomer dampeners (Brake) included in the
accessory box. The process for starting this is the same for all three pedals
and involves lifting the piston out of its location in the pedal module.
The easiest way to achieve this is to wrap your hand around the pedal face
from the front and grip the knurled edge of the piston body. You then squeeze
the piston to dislocate it from its locking position using the pedal face /
arm as leverage and lift it out of the cavity in the pedal module where it
sits.
GAS AND CLUTCH
Once the piston is clear of the main pedal module, simply pull it away from
the steel rod and remove the spring. There are four springs included in the
box, two of which are already mounted on the Clutch and Gas pedals. Simply
choose one of the other springs and reverse the process: Push the spring back
over the steel rod and then push the piston back onto the rod, ensuring the
spring is captured by the two locators.
Then reinsert the piston back into its place, reversing the process by which
you lifted it out: squeeze the piston using the pedal face / arm as leverage
and then lower it into place, ensuring that the bottom of the piston is in the
correct orientation to locate securely.
NOTE:
When you have relocated the piston in place, try pressing the pedal a couple
of times to ensure that the movement is smooth and free of any noise. If you
notice any noises as you press the pedal, try rotating the spring slightly in
place and press the pedal. Keep doing this until you hear no noises.
BRAKE
The brake is different to the Gas and Clutch as it uses the elastomer
dampeners found in the accessory box. The procedure is still straightforward
though. Once the piston has been lifted clear from the pedal module you need
to open the piston in order to access the elastomer pieces inside it. To do
this grip the knurled cap at the top of the piston in one hand and then
unscrew the body of the piston from the cap.
Once the piston body is removed from the cap, turn it upside down and shake
the elastomer pieces out. They will be slightly sticky with lubricating grease
so do have something available to wipe your hands on.
You will notice that there are three pieces of elastomer or foam in the piston
body: two of equal size and one slightly smaller one. The smaller piece must
always be present in the piston body with the other two pieces determining the
overall feeling of the brake pedal, enabling you to configure to be fairly
soft with a larger range of travel or, alternatively, as hard and limited in
travel as some real race cars. Also, the small piece should always be at the
bottom of the piston: You can alter the feeling of the brake using the
different pairings of elastomer pieces as determined by this table:
You will note that there are two small foam pieces provided, one soft and one
hard – only one of these should be used in combination with two
of the larger elastomer pieces.
NOTE:
We do not recommend using combinations that include the soft beige piece if
the PRO Pedals are hard mounted into a simulation rig / seat as this will
likely result in damage to the elastomer. Conversely, we do not recommend
using the hard elastomers if you are using the pedals in a desk-based
scenario. Unless the pedals are secured in some manner this could easily
result in the pedals tipping when applying the brake, or the pedals sliding
away from you.
Once you have chosen your elastomer pieces apply a small amount of the
included grease to the sides of the pieces and insert them back into the
piston body remembering to insert the small piece first. Two or three drops
applied to various sides of the elastomer and spread using the tip of the
bottle should be more than enough.
Once the elastomer pieces are back in the piston body you can reattach it to
the cap on the brake pedal module and then reinsert it into place using the
same method as the other pedals.
SAFETY WARNING:
With the very hard pieces of elastomer (and especially if using the small hard
foam dampener) some strength will be required to squeeze the piston body
enough to enable it to be reinserted into place. Please do take care to avoid
trapping your fingers between the piston body and the pedal module casing.
Our suggested method for doing this as depicted in this manual should help
avoid this possibility.
CUSTOM PEDAL SETUP
The PRO Racing Pedals have been intentionally designed to allow anyone to
mount the pedal modules in any manner that they wish. The pedal modules can be
completely removed from the main pedal base that they are attached to and then
mounted into a custom simulation rig in any orientation to suit your needs.
If you want to create a setup where the clutch and brake are inverted and the
gas is floor mounted then this is entirely possible. All you need to achieve
this are the pedal modules and the Pedal Hub.
First, unplug the pedal modules from the hub. Next, remove the bolts holding
the pedal modules on to the pedal base, taking care not to let them fall in
the process. Lift them away from the base and feed the cable for each module
through the holes in the pedal base, ensuring they don’t get caught. Next
remove the screws holding the Pedal Hub into the pedal base and lift it out of
the base. You can now mount the pedal modules into your custom simulation rig
as you need them – just connect them back into the Pedal Hub and then connect
the Hub into your PC or directly into the back of a compatible Logitech Racing
Wheel (if you own one).
G HUB SETTINGS
Your PRO Racing Pedals can be configured using the G HUB software on PC,
whether they’re connected directly to your PC or into a compatible Logitech
Racing Wheel.
You have the ability to adjust the sensitivity of your pedals and the amount
of pressure required to produce 100% axis output on the load cell-equipped
brake pedal.
SENSITIVITY
The sensitivity slider enables you to change the linearity of the pedal response. If you leave it at 50 then this will result in a 1:1 linear response between the physical movement of the pedal and the axis output to your racing titles. Any adjustment above or below this will introduce a curve to the axis output;
- As you increase from 50 to 100 then the pedal will become increasingly responsive at the start of the pedal travel (meaning you will see a much quicker increase in axis response at first)
- As you decrease from 50 to 1 then the pedal will become decreasingly responsive at the start of the pedal travel (meaning you will see a much slower increase in axis response at first)
It is generally recommended to leave this setting at 50, but the flexibility is there should you wish to experiment. You can see the actual response of the pedal here in G HUB; as you press it you will see the axis response indicator change, so you can easily see the results of any adjustments that you make.
BRAKE FORCE
This changes how much pressure is required in order to make the brake pedal achieve 100% axis output. The default value is 30, which for the PRO Racing Pedals equates to 30kg of force; logically therefore if you set this to the maximum of 100 then 100kg of force is required to achieve 100% axis output. The amount of force to be used is very subjective but should be considered with regards to the following factors:
- Whether the pedals are mounted into a racing rig, or sat on the floor
- The actual strength of the person using the pedals
- Which combination of elastomers you have installed into the brake pedal
For floor-mounted scenarios, 30kg is likely the maximum, unless the pedals are
secured (such as pushed against a wall under your desk); indeed, lower values
are likely required in order to prevent the pedals from sliding away from you
whilst in use.
For rig-based scenarios, the limit becomes purely about the overall strength
of the rig, the person using the pedals and the elastomers that you have
chosen to use. As mentioned earlier in the manual, it is strongly recommended
not to use elastomer combinations that include the softer beige piece when
setting forces higher than 30kg otherwise you could cause damage to this
through prolonged use.
Due to the onscreen axis response indication it’s easy to experiment with
different force settings to see what suits you the best. A good
recommendation, especially when racing cars without ABS, is to set the force
so that you can’t easily achieve 100% axis output – if you always bottom out
your brakes then it’s likely to result in the locking up of your wheels,
losing grip and sliding off the track.
NOTE: If connected to a compatible Logitech Racing Wheel with an
integrated display then you can also adjust the Brake Force setting using the
wheel, as well as see the response output of the brake pedal.
COMBINED PEDALS
This is usually only required if using very old racing titles. Pedals on older
racing wheels would often only have a brake and a gas pedal, with each pedal
representing one half of the same axis. Combined Pedal mode changes the
default configuration of the PRO Racing Pedals from fully separate axes for
the brake and the gas, to a combined mode, so that you should still be able to
use them in older titles that don’t support pedals with separate axes.
It is highly recommended for the vast majority of racing titles that this box
is therefore left unticked, in order to get the most out of your PRO Racing
Pedals.
RECOMMENDED MAINTENANCE
Your PRO Racing Pedals have been engineered to continue to operate for many hundreds of hours and feel as good as they did when you first started using them. As with your real car though, it is recommended to keep them clean by performing some simple, semi-regular maintenance.
Regular maintenance (weekly)
Clean the base and each pedal with a damp, lint-free cloth, ensuring that
there is no excess water present in the cloth
Every 200 hours
Remove any excess built-up grease (especially on the brake pedal) using a
clean cloth or piece of kitchen towel. Reapply new grease (sparingly) to
ensure continued smooth operation of the pedals. If you run out of the
supplied grease then you may source a replacement of your own. However, you
must only use a silicone-based grease/lubricant in order to prevent any
issues. Petroleum-based lubricants or Gasoline and Hydrocarbon solvents must
NOT be used as they will degrade the components used in the pedals.
