Questions about the NGM App

The All-in-One License is the full package. Stage 1 and Stage 2 for the engine control unit, gearbox tuning on every car that supports it, plus all sound features. You can flash as often as you like and go back to stock whenever you want.

The Sound License only changes how the car sounds and behaves. Crackles in sport mode, a rev limiter you can hold while stationary, Vmax removal, exhaust flaps permanently open. Power and torque stay at factory level.

Take All-in-One if you want more performance. Take Sound if you want the experience. You can start with Sound and upgrade later.

You receive an email right after the purchase with a link. Open it, install the app, and the app takes you through the remaining steps on its own.

Your licence is assigned to your email address automatically. There is no code to type in.

The last step happens in the car. Plug the adapter into the OBD2 socket, switch on the ignition and let the phone connect. The app now links the licence to the chassis number (VIN) of your vehicle and to your email address. That link is permanent.

From this moment the licence can no longer be returned, because our service has been fully delivered. See Can I cancel my purchase? below.

For life. No subscription, no renewal, no running costs.

Two conditions have to stay the same: the vehicle (chassis number) and the email address. Within those you can flash as often as you want, switch between stages and go back to stock. There is no limit on the number of flashes.

No. Licences are not transferable. They are bound to one chassis number and one user account, and that binding cannot be moved to another car or another person.

If you sell the car, the licence stops working for you. The new owner cannot take it over either, because the account does not change hands. Please factor that in before you buy.

The email with your activation link arrives immediately after the purchase. In rare cases it takes up to 24 hours.

If nothing has arrived by then, check your spam folder first. Automated emails end up there regularly. Still nothing? Write to support@ngmapp.com and quote your order number.

Yes, every update is included. New features, revised maps, support for additional control units, app improvements. You never pay twice for the same vehicle.

Yes. There is a separate upgrade product that charges only the difference. You do not buy the full All-in-One licence a second time.

The upgrade runs on the same vehicle and the same account, so nothing has to be set up again. After the purchase the performance stages appear in the app next to the sound features you already have.

A personal address that clearly belongs to one person or one company. Something like john.doe@example.com or info@yourcompany.com.

What we cannot accept are generic addresses or addresses that are obviously meant to be passed on, for example tuninglicence-vehicle@example.com. Those suggest a licence that changes hands, and licences are tied to one vehicle and one account.

If you register with such an address we may ask you to change it. If that does not happen within a reasonable period, the account can be blocked until it is resolved, and the licence is suspended for that time. Section 2 of our terms and conditions has the details.

No. One licence covers exactly one chassis number. For a second car you need a second licence.

Your account can hold several vehicles, so you manage everything in one app. Each car carries its own licence.

Use the vehicle selector on our site. Pick brand, model and engine. You immediately see whether your car is supported, what it makes from the factory and what is possible with Stage 1 and Stage 2.

The complete list of supported variants is on the supported vehicles page. If your exact engine code is missing, the car is not supported yet, even when the model name matches.

Currently 126 model variants from Volkswagen, Audi, Seat, Cupra, Skoda, Porsche and Lamborghini, model years 2012 to 2025.

Support always refers to a specific engine and generation, not to a model name. A Golf 7 GTI Performance and a Golf 7 GTI Clubsport are two separate entries with different figures. If you are unsure, check the engine code in your registration document under field P.3.

The list grows with every app update. Which vehicle comes next depends mostly on how many people ask for it.

Write to support@ngmapp.com with your model, engine code and year. We will tell you honestly whether it is planned, in progress, or not realistic.

No. It depends on the transmission and the model year.

On vehicles built from January 2022 onwards, the transmission control unit has to be unlocked once by a workshop before our software can be installed. That step cannot be done over OBD2. The vehicle page for your model states whether TCU tuning is available and under what conditions.

You need:

• The NGM App
• The NGM OBD2 adapter
• An iPhone, an iPad or an Android phone
• A stable internet connection

For the first flash we strongly recommend a battery charger. Everything else comes through the app: licence, maps, vehicle data.

Yes. The NGM App runs on Android as well as on iPhone and iPad. Both versions have the same features and use the same licence, so it makes no difference which phone you flash with.

You will find the app in the Play Store and in the App Store.

We hand the adapter to the carrier within the period shown in the shop. How long it travels from there is up to the carrier, and on cross-border shipments up to customs.

The times shown are estimates, including for express options such as DHL Express. Customs clearance, import processing, public holidays or strikes can add days, and none of that is within our reach once the parcel has left. Your statutory right of withdrawal is not affected by any of this.

Yes. There is currently no other compatible OBD2 adapter.

Writing a control unit is something else than reading fault codes. It needs guaranteed timing and a connection that stays stable for twenty minutes. Generic adapters do not implement the protocol that far. An interrupted write can leave a control unit unusable, and that is why we do not allow third-party hardware.

No. Those adapters are made for diagnostics: reading and clearing fault codes, showing live values, coding comfort functions. They are not built to write a complete calibration into a control unit.

The app checks which adapter is connected and will not start the flash with other hardware. That limit exists for safety reasons.

Only while you actually use the app: flashing, switching stages, reading fault codes. For normal driving it is not needed.

Unplug it after a successful flash. Left in the socket it keeps drawing a small current and can drain the battery over a few days. That matters most on cars that are not driven daily.

Park the car, connect a battery charger and plug the adapter into the OBD2 socket. Switch on the ignition, engine off. Open the app, select your vehicle and pick the stage you want.

The app reads the current state of the control unit, transfers the new calibration and verifies it afterwards. The first flash takes about twenty minutes. Later changes are faster because the car is already known.

When the app reports success, switch off the ignition, unplug the adapter and wait a moment before you start the engine.

For the first flash we strongly recommend it. The process takes around twenty minutes and the voltage must not drop during that time.

A modern car draws a surprising amount of current with the ignition on. A battery that is merely healthy is not the same as a battery on a charger. A voltage drop mid-write is the most common reason a flash fails.

Switch off every consumer before you start: air conditioning, infotainment, lights, seat heating. The ignition stays on for the whole process, the engine stays off.

Do not lock the car and do not open or close doors unnecessarily. Leave the phone connected. Anything that wakes a control unit or interrupts Bluetooth can abort the write.

Yes, as long as the phone stays in the car and the connection holds. You do not have to sit and watch the progress bar.

Do not lock the vehicle and stay close enough to notice if the app asks something. If the connection drops while you are away, the process stops and has to be started again.

The app is built for that case. It detects an incomplete write, keeps the vehicle in a defined state and guides you through starting again. Usually you reconnect the adapter and cycle the ignition.

This is what the charger and twenty undisturbed minutes are for. If a second attempt does not fix it, stop and contact support@ngmapp.com before you do anything else. Do not start the engine and do not try other tools.

Yes, at any time and as often as you like. Going back to stock works like flashing a stage. You select the factory setting in the app and the original calibration is written back.

You do not need a new licence for it, and you can flash a stage again afterwards. Many owners go back to stock before a workshop visit and reapply the tune later.

Work through these four points in order:

• Is the ignition switched on?
• Is Bluetooth active on the phone?
• Is the adapter fully seated in the OBD2 socket?
• Is the correct adapter selected in the app?

If all four are fine, unplug the adapter for ten seconds, switch the ignition off and on and try again. Still nothing? Send us the vehicle and the app version at support@ngmapp.com.

Not the engine control unit. The app unlocks it automatically over OBD2. No workshop, no removal, no soldering.

The gearbox control unit is the exception on cars built from January 2022. Those need a one-off unlock in a workshop before our software can be installed.

That depends entirely on the engine. The vehicle selector shows the exact figures for your model: factory output, Stage 1 and Stage 2, in horsepower and newton metres.

The gain also depends on fuel quality, engine condition and ambient temperature. Our figures assume a healthy car running the fuel grade stated for that stage. We would rather publish conservative numbers you actually reach than headline figures you never see.

Stage 1 runs on completely standard hardware. Nothing on the car is changed, only the calibration in the control unit.

Stage 2 expects hardware that breathes better. Typically a downpipe, a larger intercooler, a turbo inlet or an intake. Without those parts the Stage 2 map cannot deliver its figures and puts unnecessary load on the engine.

The vehicle page for your model lists which hardware a stage expects.

Four things, depending on what your car supports:

• Crackles and pops in sport mode
• Rev limiter while stationary, so you can hold revs standing still
• Vmax removal, the electronic top speed limit
• Exhaust flaps permanently open in sport mode

Power and torque stay exactly at factory level. The load on the engine does not change, only the sound and the behaviour.

For the performance stages we require at least 98 octane, and that is a deliberate decision.

Higher load on low-octane fuel forces the engine to pull ignition timing to avoid knocking. You lose most of the gain and keep most of the risk. Your manufacturer usually recommends 98 for these engines as well. The Sound License is unaffected, because it does not change the load.

Our maps are calibrated for standard hardware unless a stage says otherwise. The upgrades we account for are turbo inlet, intake, intercooler and downpipe. The vehicle page for your model shows which of them a stage expects.

If you have fitted parts that are not listed, tell us before you flash. Hardware the calibration does not know about changes air mass and back pressure, and the map cannot compensate for what it cannot see.

No. Our software cannot be combined with an existing tune, because the calibration in the control unit is replaced completely instead of being modified.

If your car currently runs another provider's software, the factory state has to be restored first. Whether that is possible, and how, depends on what was installed and by whom.

Yes, it can. A change to the engine software can affect your manufacturer warranty, and you should assume that it does.

You can return the car to the factory state at any time, which many owners do before a workshop visit. Be aware that a flash leaves traces a dealer can find. Going back to stock is not the same as it never having happened. If your car is under warranty or on a lease, clarify this before you buy.

More power generally means more wear. There is no honest way around that sentence.

What can be controlled is how much. Our calibrations keep temperature and pressure monitoring deliberately tight, so the engine backs off before it reaches a critical state rather than after. That costs a few horsepower on paper and buys a lot of margin in practice.

Your driving matters more than the map. Warm the engine up properly, avoid full load when it is cold, and keep the service intervals.

No. This software is intended exclusively for use on closed circuits. Modifying the engine control unit can void your vehicle's road approval.

Rules differ from country to country, and the end user is responsible for complying with the regulations that apply where the car is registered. If you intend to use the vehicle on public roads, clarify the legal situation in your country before you buy.

Talk to your insurer before you use the car on public roads. We cannot answer this for you, because it depends on your policy and on the country where the car is registered.

What we can tell you is the starting point. Our software is intended for closed circuits only, and a modification to the engine control unit can void the road approval of your vehicle. A change that affects road approval usually affects insurance cover as well, and an undeclared modification can become a problem in the event of a claim.

You are responsible for complying with the rules that apply where your car is registered. That is also stated in section 7 of our terms and conditions.

Only what is needed to identify the vehicle and write the calibration: the chassis number, the control unit identifiers and the current software state. The chassis number is what binds your licence to the car.

The app does not read position data, journey history or personal information from the infotainment system. Details are in our privacy statement.

It depends on what you bought.

Licences (digital content). Once you have given your express consent and we have provided the download or voucher code, the statutory right of withdrawal no longer applies. This follows from Article 16(m) of Directive 2011/83/EU, because the app is not supplied on a physical medium and our performance begins the moment the code is issued.

The adapter (hardware). You have 14 days from receipt to withdraw. Send us an email at support@ngmapp.com. You bear the direct cost of returning the adapter, and the refund is processed once the item has reached us in its original condition.

The binding wording is in our right of withdrawal and in section 2 of our terms and conditions.
