ECU tuning
that just feels
right.
One tuner. One direct line of communication with him. No hassle — covering the corridor from Birmingham down to Watford.
The engine's brain, brought up to date.
The ECU manages real-time data to optimise performance and fuel efficiency — but the technology it's tuned against moves on. Remapping changes that software so the engine runs better than it did from the factory.
Most non-electric cars, yes.
Rule of thumb: the older the car, the more difference you'll feel. The safest way to know for certain is to send your car's details over WhatsApp before booking anything in.

Read. Adjust. Write. Test.
Read
The current software is read straight off your ECU before anything changes.
Adjust
Fuel, boost and torque limits are adjusted for your specific engine.
Write
Safe, tested changes are written back — nothing experimental.
Test
The car is tested and refined until the delivery feels right.
Pick your direction.
Performance benefits
- More torque — stronger low-end pull
- Faster overtakes — less downshifting
- Smoother power — clean delivery
- Sharper throttle — better response
Economy benefits
- Better cruising — less effort at speed
- Cleaner throttle — less waste
- More torque, fewer revs — relaxed driving
- MPG can improve — driver-dependent
Why YK?
This isn't a factory line — it's a one-person service. That means focus, care, and aftercare, backed by elite industry technology.
One tuner. One job.
You speak to the person who does the tune, and can walk through the process with him directly. Questions welcome.
No rush.
Time is taken to check, test and refine so the car comes back running properly — not just quickly.
You get support.
Questions or issues after the fact are answered directly, not routed through a call centre.
From the last few driveways.
A handful of recent jobs — live reads, bench work, and the odd V12 for good measure.
Everything from a clean Stage 1 to fleet economy tuning.
Prices are a guide from — the exact figure depends on your ECU type. Send us your reg for a fixed quote in minutes via Instant ECU remapping.
Stage 1 Remap
The safest, biggest-bang upgrade for a standard vehicle. Typically +20–35% power and +30–40% torque on turbo diesels, with sharper throttle and less gear-changing. No hardware needed.
Stage 2 Remap
For vehicles with supporting mods — intake, intercooler, downpipe or exhaust. A custom file built around your hardware to use the extra airflow properly, without pushing beyond safe limits.
Economy Remap
Built for vans, trucks and high-mileage drivers. Optimised low-rev torque so the engine works less at cruising speed. Real-world savings of 8–15% on fuel are common on diesel commercials.
Van, Truck & Fleet Tuning
Sprinter, Transit, Vito, Crafter, Iveco, DAF, Scania, MAN and more. Economy or towing maps, speed limiter adjustment and multi-vehicle fleet pricing with one point of contact.
