A clutch feels lighter towards the end of travel. The Sim Pedals Ultimate+ clutch features a regressive spring mechanism simulating this concave force curve and also allows you to greatly adjust the pedal resistance, travel and feel.
The clutch features a 2-way hydraulic damper. This damping resists speed at the ingoing and outgoing stroke just as seen in real clutch assemblies. The amount of damping is adjustable.
A load cell provides a true linear input measurement of the pedal position. Custom non-linear output curves can freely be configured using Heusinkveld SmartControl software.
The brake features a realistic dual-stage brake system with a 200kg load cell, capable of handling actual pedal forces up to 140kg (measured at the pedal footplate). The adjustable coil spring simulates the initial pad-to-disc gap. The main brake springs are all-new custom-made Heusinkveld injection molded thermoset elastomers.
These proprietary elastomers are smooth and responsive and provide an unprecedented progressive brake resistance (concave force curve) just as you would have in a real race car. On the ongoing and outgoing stroke, they have a firm bump and rebound characteristics.
Automated testing shows these elastomers have zero performance degradation even after one million duty cycles. You can choose from a total of 9 possible resistance settings, allowing you set the pedal from very soft to extremely stiff.
The brake features a 2-way hydraulic damper. This damping resists speed at the ingoing and outgoing stroke just as experienced in actual brake assemblies. The amount of damping is adjustable
Smooth, accurate, and greatly adjustable, the throttle pedal gives you excellent control with exactly the travel, pre-load, and spring stiffness you prefer. The charts on this page show the various travel and resistance curves for each pedal. The values are measured at the ball of the foot where force is applied.
Load cells measure throttle and clutch position and brake pressure. Unlike designs with rotary potentiometers, load cells provide true linear output in relation to your pedal input. Their accuracy and durability are unmatched as they do not wear over time.
The Sim Pedals Ultimate are a full-hydraulic pedal set: All 3 pedals feature an adjustable hydraulic damper. As pedal assemblies in real cars have hydraulic flow through hoses, tubes, and cylinders, we use these to simulate the damping effect that these assemblies normally provide.
Heusinkveld Sim Pedals Ultimate+ uses a custom-made 12-bit USB controller, which works with Heusinkveld SmartControl software. After calibration every single pedal provides an output signal using the full 12-bit range, providing instant and accurate output to your favorite simulator software.
The controller enclosure is made of steel and is equipped with 4 mounting holes for easy mounting to your simulator. It can also be mounted to the underside of the optional Sim Pedals Ultimate+ Baseplate.
The pedals have passed full EMC compliance testing, guaranteeing a stable output signal regardless of other electronic components used in your simulator.
The Sim Pedals Ultimate+ come with a powerful configuration tool allowing you to set up your pedals in ways not previously possible: SmartControl. Working together with all-new electronics, SmartControl allows for instant mapping of (non-linear) pedal output curves, pedal deadness and brake pedal force.
These adjustments can be made without having to recalibrate the pedals (including iRacing). All settings can be saved into profiles, which can be loaded again in a few mouse clicks.
Mapping pedal output curves
A key feature of SmartControl is the ability to set custom signal output maps per pedal. Traditionally race simulator pedal output has had a one-on-one sensitivity in relation to the pedal input. SmartControl allows you to map non-linear output curves using 5 zones (six input parameters).
Each pedal has a Curve Type pull-down menu with pre-defined output curves. You can also select the option to make a custom curve and manually set the desired pedal output percentage for each zone. You have complete freedom to set your own shapes.
Deadzones and brake force adjustment
SmartControl offers quick and easy adjustment of pedal deadzones. The effect of changing these adjustments can be seen visually and realtime. Also the required brake force to get 100% brake output in your simulator can be set in a few mouse clicks.
There is support for an unlimited amount of profiles within SmartControl. Saving and loading a profile is done in a few mouse clicks. Because profile data is saved relative to your calibration values, it is possible to exchange pedal profiles between Sim Pedals Ultimate+ owners.
Your Sim Pedals Ultimate+ are pre-calibrated during assembly and can be used as a plug&play device. All adjustments in SmartControl can be made without having to recalibrate the pedals.
In case you do need to recalibrate (for example after making certain mechanical adjustments to the pedals), SmartControl has an easy to follow calibration wizard.
