JG Mechanic Script: Workshop Tablet & Dyno

One car, start to finish

A player rolls into the workshop with a tired sedan. The mechanic connects the car to the tablet and starts a dyno pull: about 30 seconds later the horsepower and torque curve has climbed through the rev range, and the final graph can be shown to the owner or anyone standing nearby. From there it is a conversation about what to change, and every change the mechanic fits lands on an invoice that is already being written.

That is the loop JG Mechanic Script is built around, on ESX, QBCore and Qbox. It is a mechanic job rather than a map: it supplies the menus, the tablet, the items and a lift prop, and your city supplies the workshop.

The tablet runs the shop

Servicing, dyno runs, performance tuning, invoices, order fulfilment and business management all live on one tablet, opened by command or by item. Staff are not pinned to markers, so they can walk around the car while they work. Connect a vehicle to work on it, or open the management side with no vehicle attached at all.

Invoices fill in as tunes, NOS or services are fitted. The mechanic sets the prices and sends it to the customer; an invoice can also be started from scratch, saved for later and resent, and it stays in sync for everyone employed at the business.

What can be done to the car

| Work | What the player gets |
|---|---|
| Cosmetic tuning | Every GTA option, including recent DLC additions such as the seven Chop Shop plate styles. Apply and pay as a customer, or order it for a mechanic to fit. Automatic camera angles or a free camera for previews. |
| Respray | Searchable base colours, primary/secondary sync and a pearlescent toggle, or full RGB. Chameleon paint reaches wheels and interior where the vehicle supports it. |
| Stance | Ride height, camber and tracking set per wheel, from the tuning menu or an item. Synced to other players and kept when the car goes into and out of a garage. |
| Performance | Pre-configured engine swaps with their own sounds (V12, V8, V6, I4), plus tyre, drivetrain and brake upgrades. Add your own options in config and define how each changes handling or sound; streamed custom engine sounds are supported. |
| Manual gearbox | Convert any non-electric car from automatic to manual through the tablet, paid by item or society money. Good shifting gets more from the engine; shifting too late damages it. |
| Lighting | LightingControl+ is an inventory item that toggles RGB xenons and underglow and runs effects such as rainbow or flash. |

Any tuning option you do not want can be switched off in the config.

Keeping cars coming back

Servicing wears parts down by distance driven. Once a configurable mileage is reached, the car needs a mechanic to inspect it and replace worn parts before it is back to full performance. This uses jg-vehiclemileage, which is free and included.

Damage has four routes: repair at a tuning location, place a repair order, use a repair kit, or apply duct tape as a stopgap to get back on the road. Repair costs can scale with the vehicle's value.

Setting prices

Each category (performance, cosmetics, wheels, respray and the rest) carries its own price, with multipliers layered on top. Prices can also follow the vehicle's value, read from JG Dealerships, QBShared or vehicles.meta, so an upgrade on a supercar costs more than the same upgrade on a hatchback.

Workshop fittings and admin

• Car lift: an interactable lift prop that can be placed anywhere on the map and locks itself to a mechanic business.
• Item binding: the tablet, tuning order installs, stancing, engine swaps, NOS, brakes, repairs, cleaning, lighting control, servicing and more can each be tied to an inventory item.
• Discord logs: webhook logging to up to seven URLs.

Sync and resource use

Animations and effects go through OneSync Infinity state bags, so the car a mechanic has just built looks the same to every player around it. The resource avoids unnecessary infinite loops for that syncing and reports 0.0 to 0.1ms on resmon at idle, including on large servers; it rises only during heavy client effects such as stancing, NOS or LightingControl+.
