Spec-Series Control-Tune Lock

QBCore/QBox spec-series that captures each entrant's own mods, forces one identical server-defined control tune for the race, and restores every car's saved tune after.

NON-TESTÉ — the reference Lua is syntax-validated, not run in a live FiveM server. Adapt and test on your own dev server before shipping.

Description

A spec-series control-tune lock for QBCore or QBox: when a race starts the server pushes one identical control tune to every entrant after snapshotting each car's own mods, then restores each saved tune when the race ends. Servers sell this because a true spec series — where the driver is the only variable — is the format competitive leagues are built on.

Known Failure Modes & Corrective Prompt

  • Client-chosen tune — entrants applying their own setup defeats the spec; the one SPEC_TUNE and the locked roster live on the server.
  • No snapshot — applying the spec without capturing originals first means restore wipes the real tune; captureMods before applyMods.
  • One-sided net event — defining spec:unlock on only one side leaves cars stuck on the spec tune; both sides use RegisterNetEvent + AddEventHandler.

Corrective re-prompt: "On spec:lock, savedMods = captureMods(veh) BEFORE applyMods(veh, spec); broadcast SPEC_TUNE from the server to every series.locked id; and only spec:unlock restores savedMods — clients never define their own tune."

Framework Integration

  • ESX: not in scope for this entry (QB/QBox series tooling); port by swapping the core export if needed.
  • QBCore: local QBCore = exports['qb-core']:GetCoreObject(); trigger spec:start/finish from your race host with the entrant source list.
  • QBox: use exports.qbx_core to resolve the entrant roster; the spec tune and restore stay server-driven.

Profit Potential

$250–$3500/mo on Tebex (expected ~$900). [INFERRED] within the $50-389 script band against the signal-scraper tebex_snapshot corpus (n=100, median seller $11.85K/mo), set for a rising tuning-tied spec niche.

Trend Signal

↗ rising — strategy: niche-selection.md vehicles/tuning row → rising (3.75); spec/control-tune is tuning-tied.

Sales Angle

Position as the spec-racing mode that makes the driver the only variable — one locked tune for the race, every car's own tune restored after. Recommended Tebex price $289.
