Ghost Immobiliser FAQ's

Prices start from £449, however, most vehicles are £449. Typical exceptions to this are Jaguar/Land Rover group vehicles which we may charge a little more for. 

Best way to be safe is to give us a call or send us a contact form on our website.

Please note, we are governed on price by Autowatch, the manufacturer. Some of our older marketing material, such as our video, states that the price starts from £399. This used to be the case but since the Ghost Immobiliser has become TASSA approved, we have been required to increase our prices to £449 as per Autowatch’s terms and conditions.

Tools will not pick up the Ghost immobiliser as it does not give off any radio frequency signals, leaving thieves clueless as to why the vehicle won’t start. Even if they recognise, during the offence, that the Ghost immobiliser is installed, they will not be able to start the car without entering the PIN.

You can change the PIN at any time. During our installation demonstration, we will walk you through how to change your PIN and show you the buttons you can set your PIN to. You can have up to 20 buttons in your combination.

The best way to find out if the Ghost is compatible with the car is to check using our compatibility list at the top of this web page. 

It’s down to your discretion as to whether or not you want to disclose and compromise your PIN. You can change it at any time. 

However, the Ghost is equipped with a service/valet mode which you can activate to allow someone to drive your car, without the PIN, for a short time.

Button availability is made on a case-by-case basis. We’ll be able to tell you when you speak to us on the phone or via email.

The Ghost Immobiliser is TASSA approved. In some cases, this will reduce your insurance premium.

These FAQ's Answer Most Questions

Whilst a remap will add a small amount of extra strain to the vehicle, all of our files are well within the safe parameters of the vehicle’s components (such as the engine, transmission and drivetrain) capabilities. We would only increase engine output to what we deem to be safe as it wouldn’t be beneficial to us or you to push your vehicle to anything beyond that.

It is not in our interest to push your vehicle past its’ limits. We simply wouldn’t have a business if we blew cars up on a daily basis.

There are a couple of ways for a remap to be detected. The most cost effective and most commonly used method by manufacturers is to check the CVN with diagnostics tools. CVN stands for ‘calibration verification number’. In short, this number shows the number of times an ECU has been flashed. If an ECU has a higher CVN than it should, a manufacturer’s diagnostic tools will be able to detect this.

With most modern vehicles, our industry-leading remapping software can successfully flash an ECU whilst keeping the original CVN. Meaning diagnostic tools would not be able to detect the remap.

That said, a remap is NEVER undetectable. If someone wants to dig deep enough, they will eventually find it.

A good workaround for this which covers most instances is to have the vehicle returned to stock which we are able to do.

A very common question with very common misconceptions. Ultimately, there is no such thing as a generic map. ‘Generic’ implies that we could use any tune file on any vehicle. Every tune we apply has been custom calibrated for your vehicle make, model and drivetrain.

For stage 1 and most stage 2 files, we can use pretested, safe and proven solutions. Why? Because we know it’s safe. 

What people mean to ask is ‘is it a live remap?’. Short answer, no. But why would you need a live remap?

Typically, a live map, undertaken whilst the vehicle is dyno tested is only really required for vehicles with heavy modifications (excluding breathing mods).

A common misconception, no doubt born in a ‘know-it-all forum’ somewhere, is that for some reason, a map that isn’t a live map, completed on the dyno is bad. This is simply untrue. A 50p map from ebay, on the other hand won’t be doing your car much good.

As mentioned, all of our files are custom calibrated for specific vehicles and have been dyno developed and road tested in the first place to ensure safety, prove gains and result in a reliable tune. Take forum talk with a pinch of salt.

Some manufacturer’s diagnostic equipment may detect a remap.

Many forward-thinking manufacturers turn a blind eye to a quality remapping service, knowing that a properly enhanced vehicle can only ever benefit them. The official line from most manufacturers is that if a modification causes a problem with the vehicle, then the part of the vehicle affected will not be covered under warranty, this does not mean a unilateral cancellation of the whole warranty.

Our best practice and advise is that if you ever need to take your vehicle in for warranty work, bring it back to us to flash on an original file. This way we can mitigate the chances of the remap being discovered.

Whether a manufacturer voids your warranty or not due to a remap is usually at the discretion of the dealership. For vehicles with aftermarket warranties, it is incredibly unlikely that a remap will be looked at or investigated.

At Phantom Tuning, we cover stage 1 ECU tunes and occasionally Stage 2 remaps. When it comes to this level of remapping, a dyno is not always needed. The reason for this is our remapped files have already been tested on a dyno where a slave or donor vehicle was remapped.

This means that we’ve already stress tested and proven the figures that our remaps can provide on a well-maintained vehicle. For stage 1, the donor vehicle is identical to yours, so there is no need to dyno test the file again. For stage 2, the need for a dyno depends on whether or not there are any discrepancies in modifications.


As part of our service, we will before and after road test a vehicle when possible, to ensure the remap behaves as intended.

Ultimately, a remap will optimise the engine. Therefore, it is common to expect improved fuel economy under normal driving conditions.

If you’re expecting to be able to drive spiritedly and still gain another 20% fuel economy, your expectations are unrealistic.

Under normal driving conditions, most of our customers see slight improvements in fuel economy, anywhere from 5% to 15%.

Manufacturers restrict the performance of a vehicle for multiple reasons. An example would be warranty lifespan. It’s in a manufacturer’s interest to ensure their vehicles underperform to reduce the number of warranty claims during the warranty period. It also enables them to extend the time and mileage in which a warranty can be offered.

Increasingly now, manufacturers are saving costs by limiting the number of engine sizes they offer and instead using different versions of the same engine. This enables them to not only save money on research and development but also to charge more money for a vehicle with a higher power output.

For example, the Ford Transit Custom is available in: 100BHP, 125BHP and 150BHP. However, each of them uses the same engine, transmission and drivetrain. The interesting thing is that each of the versions are capable of 180BHP. They simply charge more for the higher-powered versions.

Manufacturers also need to bear in mind that their vehicles are being sold across the globe with various tax brackets, insurance groups and environmental conditions. As a result, they need one universal map to suit all scenarios whilst ensuring maximum sales of the vehicle in question.

Nothing. Typically, all that the different driving modes tend to do is change your throttle mapping. Some vehicles also add weight to your steering and tighten the suspension.

With a tune, the power is changed across all modes. your existing modes will still behave the same and each mode will have its own custom throttle calibration.

Nothing… If your vehicle goes in for service work at a main dealer, even if it’s in warranty, you needn’t worry about anything in relation to a map being detected.

However, if a dealer needs to apply a software update to your vehicle, there is a chance you may lose your map. If you do, we can reflash the modified file on to your car for a small fee of £60 inc. VAT.

We do. Stage 2 requirements are: upgraded intake & decatted or sports catted downpipes.

An average car will gain an extra 20-50bhp for stage 2, depending on the vehicle. 

The calibrations for stage 1 and 2 are quite similar, however, most of the additional gains will come from the physical modifications rather than the tune itself. For example, if you’re already running a stage 1 tune and have already applied stage 2 modifications, it’s unlikely that you’ll feel too much difference in changing the map to a stage 2.
