Tuning module or remap

GAN tuning module or ECU remap

Today there are two ways of chiptuning: an additional tuning box (tuning module) and software changes in the ECU (remapping).

The guide below shows why the use of tuning modules is now preferable to remapping the engine control unit (ECU).

Point-by-point comparison

Engine

ECU remap Loss of the manufacturer’s warranty after an ECU remap

In case of ECU remapping you will lose your manufacturer’s warranty, even if the breakdown is a result of a manufacturing defect.

GAN tuning module With GAN, there’s no need to worry about your engine

With a tuning module, no engine components are altered, so there’s no need to fear that the engine will wear out prematurely or that mechanical parts will break as a result. GAN is so confident of this that it offers its customers up to 2 years’ additional engine warranty. At the same time, your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

Fine-tuning

ECU remap Generic engine remaps

Remaps, in most cases, are developed for a whole vehicle line regardless of the specific engine, so you cannot readjust individual components.

GAN tuning module Customised GAN modules

GAN modules are programmed specifically for your engine. In addition, GAN GT and GAN GTL offer up to 18 fine-tuning modes to suit your needs at any time and make driving even more comfortable.

Installation

ECU remap Complex and expensive remapping

Remapping takes much longer and requires special expensive equipment and an experienced specialist to ensure no damage is done to the ECU.

GAN tuning module Simple installation of the GAN tuning module

You don’t need a lot of time or trips to a garage to install the GAN tuning module on your car. Installation usually takes 10–15 minutes and does not require professional knowledge.

Safety system

ECU remap Possible overload due to remapping

The manufacturer’s protection mechanisms can be overridden when the ECU is reprogrammed. This can result in overpressure and overheating, and the engine can then fail quickly.

GAN tuning module Double safety system of GAN modules

Since the tuning modules do not alter the ECU, all safety systems work properly. In addition, the repeatedly tested hardware provides extra protection against premature engine wear.

Reset to factory settings

ECU remap Complicated and long factory reset

It’s very difficult to return the ECU software to factory settings. It takes a lot of time and effort, and your dealer can still tell that the software has been changed.

GAN tuning module Instant reset to factory settings

One tap in the app returns your car to factory settings. The module can be removed in a few minutes and leaves no electronic or mechanical traces: the factory ECU software is never changed, and your manufacturer’s warranty is preserved.

How it works

GAN tuning modules are easy to install and easy to use

GAN modules for turbocharged engines connect between the engine control unit and the sensors. They modify the sensor signals in real time to increase power or reduce fuel consumption. Installation for naturally aspirated engines is even simpler – just plug the device into the OBD-II port. Unlike a remap, GAN modules are independent intelligent devices: their own processor keeps the engine safe while increasing power and torque.

up to 15%fuel savings

Save money and fill up less often

With GAN, you don’t have to choose between more power and better fuel economy: GAN devices give you both. With an economical driving style, GAN can lower your fuel consumption by up to 15%.

As power increases, torque rises too, so you change gear earlier and less often. This lowers fuel consumption. GAN works with the factory ECU software, so the trip computer shows your real, lower fuel consumption – something a remap cannot guarantee.

From Germany

Made in Germany and tested in various conditions

It’s no secret that German-made products always have a quality mark. Our company is also from Germany and today our products are used all over the world. More than 37,000 customers enjoy the new features of their car.

GAN app

Fine-tuning via your smartphone

GAN developed a mobile app that connects to the tuning module via Bluetooth. You can choose among several driving modes that were designed and configured individually for each engine: DYNAMIC, ECO, SPORT and STOCK.

Devices for turbocharged engines also have a warm-up timer. It protects your engine by reducing the load on it while it warms up in cold weather. The module software is customised specifically for each engine. But if you want to fine-tune it further, you can do so in a special section of the mobile app.
