Cross sim haptics for SimHub
MCP4SH turns the live data from supported sims into haptic feedback that is easier to read and more consistent from one title to the next. Braking, tyres, road, suspension, drivetrain and chassis cues are shaped to work together, so changing sim should mean driving rather than rebuilding the feel of your rig.
Under the hood, MCP4SH interprets what the car is doing before the supplied haptic effects render it. That is the practical idea behind the wider MCP4H approach: preserve useful meaning, then adapt how it reaches the driver and the hardware.
I built MCP4SH after losing my own SimHub profiles and realising I did not want to rebuild a believable shaker setup for every sim I played. The question became simple: could the software do more of the interpretation work, so I could switch games without second guessing the rig? That became MCP4SH.
Development note: AI has been used for drafting and faster iteration. The MCP4SH codec architecture itself was ideated, designed and constructed by me.
The core haptics experience stays free. Premium adds the deeper control layer and directly supports continued development.

Current public release
MCP4SH 1.1.14.1 is a small mapping-convenience hotfix on top of the 1.1.14 installer/update reliability work. The haptics baseline is unchanged; this one makes it easier to correct common physical routing mistakes without rerunning the whole mapping wizard.

Wut?
Telemetry is simply the live data coming from the sim. MCP4SH turns that data into clearer tactile cues for grip, tyres, suspension, road, drivetrain, braking and chassis load.
How?
Instead of letting every effect buzz on top of every other effect, MCP4SH tries to keep the useful parts readable as one moving car. You should spend less time wondering what the vibration is and less time trying to tame it.
And why should i care?
When the tactile language stays consistent, you spend less time asking what an effect means and more time reacting to the car intuitively. MCP4SH is not a pace cheat. It is better information through the rig.

Free gets the intended MCP4SH experience onto your rig. Premium keeps that curated baseline and adds deeper control over how it is expressed on your hardware.
Supported titles
MCP4SH is built around shared telemetry semantics rather than a separate hand-tuned haptic stack for every game. The source telemetry still differs between titles, but the aim is to keep the interpreted feel and effect relationships recognisable when you switch sim.
These are the titles and series currently covered by the MCP4SH land-chassis path.

Validation in progress
American Truck Simulator and Euro Truck Simulator 2 appear to expose enough useful telemetry through SimHub to be promising MCP4SH candidates. They are not being advertised as fully supported until the live property mapping has been validated.
Flight · v1.2
DCS and Microsoft Flight Simulator 2024 are already part of the v1.2 development and validation path. Dedicated flight semantics are being added rather than simply re-labelling the automotive effect model.
Telemetry completeness and signal quality differ by title, so not every effect has identical source data in every sim. MCP4SH is designed to preserve those differences where they matter instead of inventing detail that is not present.
Why "String Theory"?
In performance-driving instruction, "string theory" or the "string analogy" asks you to imagine the steering wheel and pedals connected by an invisible string. As steering input increases, brake or throttle input generally has to give something back; as the wheel opens, more longitudinal input becomes available. It is a memorable way to teach that steering, braking and acceleration are not independent on/off commands when the tyres are already using a finite grip budget.
MCP4SH borrows the relationship idea, not a literal steering-to-pedal formula. The plugin treats tyre, suspension, road, drivetrain and chassis information as parts of a coupled vehicle state, then translates the useful relationships into tactile cues that can coexist without simply piling more vibration on top. The driving analogy is deliberately simple; advanced coaching material also points out that the real relationship changes with vehicle balance, rotation, steering feedback, line and timing.
MCP4SH Premium
The free version gives you the core MCP4SH experience and guided setup. Premium keeps the same curated baseline, then adds deeper control for shaping how that feedback is expressed on your own rig. Buying Premium also directly supports the compatibility, testing and engineering work behind MCP4SH.
Premium is €12.99 as a one time purchase. The current Premium entitlement is a perpetual personal licence for 1 machine. There is no subscription and no renewal fee. The core version remains free. The earlier Pioneer tier is retired and existing Pioneer users retain their original grandfathered entitlement. Checkout remains the source of truth for promotions, location dependent taxes and the exact Premium feature set.
What you get
MCP4SH.motion properties are there for people who knowingly want to experiment.Support baseline
MCP4SH is built as a telemetry-to-haptics codec rather than a usual SimHub profile made from standalone raw formulas. The plugin processes available telemetry signals from the game before exposing shaped public outputs used by the supplied SimHub profile.
That means separated graphs, manually edited formulas, or heavily modified profiles can be useful for personal experimentation, but they are not the supported reference for accurately and methodically judging whether MCP4SH is behaving correctly. The supported baseline is the current supplied MCP4SH plugin, profile, generated channel map, and Setup Assistant workflow.
The frequency ranges, tactile carrier choices and vehicle-motion interpretation are not arbitrary lookup tables. They are informed by published work on tactile perception, vehicle vibration and transfer behaviour, then tested empirically against the telemetry and hardware MCP4SH actually has to work with. Research provides the engineering context; telemetry quality, calibration and the real rig still determine the implementation.
FAQ
If your current hardware is driven by SimHub ShakeIt Bass Shaker effects, then yes, it should.
However, and I can not stress this enough: Mounting discipline is crucial, not optional.
As I learned myself, all transducers on any given rig should be:
- mounted correctly: flush with its mounting surface or directionally in-line with/on top of the (virtual) axis along which the vibrations will travel.
- hard-mounted: nuts and bolts, heavy duty doublesided mounting tape or strong zip-ties.
- isolated/separated: use shock-absorbing washers or bushings to isolate each transducer (sounds counterintuitive, i know), this limits frame/rig cross-talk.
use this rule of thumb: if you can hear the shaker more than you feel it, it's not mounted right, or something on your rig is loose/rattling.
Reality check
MCP4SH handles interpretation, consistency and setup guidance. Your transducers, mounting, amplifier chain, gain staging and simulator data still define what the hardware can physically reproduce. The goal is not magic. It is a stronger starting point with much less unnecessary tuning.
No subscription. No renewal fee.
Premium is a perpetual personal licence for 1 machine and it also directly supports continued development. Still deciding? The core experience remains free. Already using it? An honest review is useful too, whether the experience has been good, bad or weird.
