ECU Live Remap Tuner

An in-car ECU remap UI with fuel-map/boost/rev-limit/launch-control sliders that save to named tune profiles persisted and validated server-side.

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

An in-car ECU tuner where a mechanic flashes a fuel map, boost, rev limit and launch control, then saves the whole map as a named tune profile a player can swap between. Deep software-tune UIs are rare at any real quality, so this is the flagship that anchors a premium tuning garage and justifies a high Tebex price.

Known Failure Modes & Corrective Prompt

  • Client-side profile — the tune is built and stored locally, so a crafted event injects a 3x boost map. Sanitize + store on the server.
  • Missing flash anim load — TaskPlayAnim fires before the dict loads; no animation plays.
  • Half-wired loadecu:load has no server AddEventHandler, so named profiles never come back.

Corrective re-prompt: Add a server-side sanitize() that clamps fuel to [0.5,1.5], boost to [0,1], revLimit to [4000,12000] and coerces launch to a bool, reject names over 24 chars, store profiles keyed by plate+name, and ensure ecu:load has a server AddEventHandler that returns the stored profile via ecu:loaded.

Framework Integration

QBCore: resolve with exports['qb-core']:GetCoreObject().Functions.GetPlayer(src); gate /savetune to the mechanic job and persist profiles via oxmysql. QBox: exports.qbx_core:GetPlayer(src) and lib.callback (ox_lib) for the load round-trip if you prefer callbacks over events. ESX: not targeted here, but the same server sanitize() + oxmysql store ports cleanly via exports['es_extended']:getSharedObject().

Profit Potential

$400–$6000/mo on Tebex (expected ~$1500). [INFERRED] Priced near the top of the $50-389 band; a hot, undersupplied deep-tune niche (corpus median seller $11.85K/mo, signal-scraper tebex_snapshot n=100) supports premium units.

Trend Signal

🔥 hot — inferred: deep software-tune UIs are rare at quality; pre-launch tuner-RP demand outruns supply [inferred].

Sales Angle

Position as the premium deep-tune flagship — named profiles, sliders, launch control — that commodity upgrade menus cannot match. Recommended Tebex price $249 standalone.
