Warrington's ECU Tuning Workshop
We don't tune everything — we specialise. Day in, day out we work on BMW and the VAG group (Audi, VW, SEAT & Škoda), so we know these engines inside out. Every map is custom-written for your exact vehicle and proven on our in-house 4WD linked V-Tech dyno — real, measured gains, never a generic off-the-shelf file.
Petrol — 20i · 40i · M40i · M-series. Diesel — 320d · 330d · 335d · 340d · 640d · M50d · X3/X5 M40d and the wider range.
TFSI & TSI petrol and TDI diesel — Golf, A3/A4/A5, Leon, Octavia, Cupra Formentor/Leon and Bentley.

FAQs
The things customers ask us most — safety, warranty, timing, and what makes a dyno-developed map different.
Yes. Before any tuning we carry out a full health check to make sure the vehicle is running correctly and fit for tuning, and every map stays within the safe operating limits of the engine and its components. We never push a car beyond what it can safely handle — and if we spot any issues during the health check, we'll advise you before going ahead.
It's possible. Some manufacturers treat ECU modifications as an unauthorised change and may not cover related repairs. We always recommend checking your warranty terms and speaking to your manufacturer or dealer before booking — and we're happy to advise if you have any questions.
Stage 1 dyno tuning typically takes 2–4 hours depending on the vehicle and any extra services booked alongside it. You're welcome to wait on site — there's a warm, comfortable waiting area with free Wi-Fi, drinks and Netflix.
Yes. You'll get a full before-and-after printout showing power, bhp and torque, so you can see exactly what the tune has gained across the rev range. It's something we're proud to hand over — there's nothing to hide when you tune on a dyno.
We're appointment only — each session needs dedicated dyno time and preparation, so we can't take walk-ins. Booking is quick and easy: secure your slot online in a couple of minutes.
Every tune we write is developed in-house on the rolling road, measuring and adjusting power, torque, air-fuel ratio and boost in real time so it's fully optimised for your exact car and stays within safe limits. Mobile flashes and cheap off-the-shelf maps are written blind and can't offer that — no generic files, no guesswork, and a full before-and-after dyno printout every time.
