Noble-Dyno
how it works
Fox & King · shock valving

Tune shocks against the dyno, not the textbook.

Enter a vehicle's full spec. Noble-Dyno computes the damping target and a buildable shim stack, then learns from your Laba7 dyno runs — calibrating the model and correcting the stack until the measured curve hits target.

The closed loop

01

Target

Sprung mass → wheel rate → ride frequency → critical damping → target force curve. Flags a wrong spring.

02

Suggest

Inverse solver searches real Fox/King shim sizes for a buildable stack that matches the target.

03

Dyno

Build the stack, run it on the Laba7, export the CSV. The dyno is ground truth.

04

Correct

Calibrate the piston from the run, read the delta by zone, and re-aim the stack. Repeat → converge.

Built for the shop

Real physics, auditable

Shim stacks as clamped annular plates; orifice flow for bleed, ports, and bypass. Every constant cited — uncertain ones are corrected by the dyno, never hidden.

Per-piston calibration

Each Fox/King piston earns a calibration state from real runs — theoretical → partially → calibrated. The model gets truer with every dyno pass.

Buildable output

Every suggested stack is real part numbers and sizes — compression and rebound, bleed, gas pressure, crossover. Copy it to the bench.

Overlay you can read

Target, suggested, and measured on one plot — comp up, rebound down, LSC/HSC/LSR/HSR zones marked. Read force at any velocity.

Yours, offline

All data local in SQLite. No cloud, no accounts, no telemetry. Calibration data exports to JSON for backup.

Mac & Windows

Native desktop app — real installers, not a web portal. Dense and fast, made to sit next to the dyno.

Installing

macOS

Open the .dmg, drag Noble-Dyno to Applications. It's unsigned, so clear Gatekeeper once:

xattr -dr com.apple.quarantine /Applications/Noble-Dyno.app

Or right-click the app → Open → Open.

Windows

Run the .msi. SmartScreen will warn it's unsigned:
