ADAPTIVE TUNING MODULE

MADE IN GERMANY 🇩🇪

Effortless Performance Enhancement with Plug & Play Technology

At JF Automotive, we are proud to introduce our latest Plug & Play Adaptive Tuning Module, designed with custom software to enhance vehicle performance without modifying the ECU. As modern vehicles become more complex, many models cannot be tuned directly through the ECU. To overcome this challenge, we have developed an advanced Adaptive Tuning Module, which can be installed in under 45 minutes and removed without leaving a trace.

  • Wide Vehicle Compatibility – Works with models from 1999 to the present day

EXAMPLE DYNO GRAPH

Please note this dyno graph shows raw data measured at the wheels. Our system then calculates drivetrain losses to produce engine power figures.

How Does the Adaptive Tuning Module Work?

There are two main methods of tuning modern diesel engines:

  1. ECU Remapping (Chip Tuning) – This method involves reading the car’s ECU software, modifying it, and writing a new performance-optimized version.
  2. Plug & Play Tuning Module – Also known as a Piggyback ECU, this external module connects to the existing wiring using manufacturer-approved connectors. The tuning module intercepts signals from the engine sensors and adjusts them in real-time, increasing fuel injection timing and optimizing turbo pressure to improve performance while maintaining safe air-to-fuel ratios.

Our Commitment to Quality and Customer Satisfaction

At JF Automotive, we stand by the quality of our digital tuning modules. Many of our units carry TÜV certification, a mark of excellence in engineering and safety. We rigorously test our products to ensure reliability and performance.

  • Customisable Power Settings – Select from multiple power levels based on your driving needs
  • Optional App for some models – Easily toggle the module on or off from the app.
  • Professional Installation & Support – Available at our approved workshops, or detailed guidance for self-installation
  • Compatibility with a Wide Range of Diesel Cars & Vans – Designed to work seamlessly.

FAQ's

Do you offer a 12 month warranty?

Coming soon…

What is motorsport use?

Motorsport-exclusive components are explicitly designed for track use. While they can be installed on any vehicle, it’s important to note that using such parts renders the vehicle unsuitable for road use and may result in MOT failure.

Will the lifespan of my engine be reduced?

No! Our remaps are designed specifically to improve the performance of your vehicle whilst remaining within the tolerances of your vehicles’ components.

Sadly, in attempt to achieve ‘big numbers’ some other companies over tune engines, placing excessive stress on the engine, transmission, cooling systems, etc, leading to reduced life span and reliability of the vehicle. We pride ourselves in producing reliable remaps which do not over stress your vehicle but still produce impressive results.

What is covered with the 30-day money back guarantee?

In any case where a customer is dissatisfied with any ecu remap software supplied, within thirty days of the supply date, the customer can request their money back. In order for any refund to be processed, the customer must present their vehicle to our workshop and allow our technicians to restore the vehicle to its original state. On successful completion JF Automotive will refund the cost of the remap to the customer.

No refund can be granted unless the vehicle is returned to the original state by JF Automotive. The 30-day money back guarantee only applies to stage 1 remaps and does not apply to other services like pops and bangs, parts or dyno sessions.
If another modification is purchased alongside a tuning file, which relies on a remap to operate, only the cost of the file is covered by this guarantee. We reserve the right to withdraw this 30 day money back guarantee.

Read full Terms and Conditions

Can the remap be reversed?

Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.

What if a main dealer wipes the map with a software update?

No problem, simply bring the vehicle back in and we will take a fresh read of your ECU and write you a new map file free of charge. We offer this as part of our lifetime software support.

Do I need to notify my insurance company?

Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle. Many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased economy however a failure to disclose modifications may invalidate your policy. You may wish to enquire with your insurer if the modification will affect your policy prior to choosing one of our services.

Why we don't you offer ECU remapping for £200?!

We get asked, “Why do some tuners charge as little as £150?” There are a few factors as to why we do not offer remapping for £100-£200!

We supply custom written files for each vehicle that we remap that take in to account condition, milage and customer request of each vehicle. Our services are fully insured with a 30-day money back guarantee and lifetime support for the tuning software supplied. We constantly invest in the most up to date tuning and diagnostic equipment and software and we offer a quality service to all our customers.

Overall our custom supplied tuning software is of the highest standard that we know of, so if you want the best of the best, choose JF Automotive.
