JFS Tuning is the UK’s premium provider of high quality Custom ECU Remap’s using the latest custom remap  technology available in UK Today.

When it comes to your pride and joy, only the best is good enough.

WHY REMAP?

All car engines are initially de-tuned by the car manufacturers by default. This is because the cars are sold all over the world, so the ECU software settings have to account for these many different factors. To modify this default software for improved performance, you need your car remapping to unleash its true potential.

Here at JFS Tuning, we custom remap every single vehicle that we work on. Most car remapping companies can only offer non-specific tuning files which were originally made for another vehicle and not tailored to your car. Our engine remap involves tailoring the entire process specifically your car.

Its – Safe. Quick. Economical.
Performance remapping is the secret to maximising your car’s potential and drive ability. Think of it as “tuning” the car’s engine. We don’t tamper with or replace any of your car parts to perform our remap. Due to this, the procedure is extremely straightforward, inexpensive and quick for us to perform.

Here’s just a few of the Many Benefits of Engine Remapping:

ECO Remaps -From £195
Stage 1 -From £195
Stage 2 -From £245
EXTRAS -from only £45
Custom OBD Remap
Custom Bench Remap
how Does the remapping take place?

Vehicle's Performance IN 3 STEPS!

Step 1

Diagnostic & Read ECU

At JFS Tuning, we specialize in creating customized remapped tuning files specifically tailored to your vehicle’s needs. Our process starts with a comprehensive diagnostic check to identify any significant fault codes that could impact the ECU writing process.

Step 2

Original ECU Files

We use advanced tools such as Autotuner and Kess V3 to extract the original file from your vehicle’s Electronic Control Unit (ECU). All ECU reading and writing processes are performed with genuine hardware and software, ensuring absolute precision and reliability.

Step 3

Modify & Write File

Once the ECU file is modified, we rewrite it into your vehicle to optimize its performance. To guarantee everything operates seamlessly, we conduct a final diagnostic check and clear any detected fault codes.

Been today to get my dad's 2.0TDI Ateca remapped. The difference it has made is massive and pulls like a train now in all gears. I came a few months ago for my 1.6TDI Leon for DPF delete & EGR remapped. The bloke even threw in his map free of charge which was a nice gesture. My car runs a lot smoother and quieter since and pulls miles better in every gear. Would recommend you guys to anyone! Cheers lads

Great set of lads and very quick and responsive. My car was in a bad way and I was panicking, however, they came to the rescue and the very next day, my car was up and running again. The price was also very affordable. Easy to work with and very reliable. I will be back if my car every has issues.
