ECU tuning at AB Customs

Vehicle Tuning

ECU tuning adjusts your vehicle's software to improve power, torque and response. Every tune is built around your vehicle and setup—not copied from a generic file.

Average turnaround: most remap tunes are done in around 1 hour — drop in, wait, drive away tuned.

Performance Remaps

If you're after pure performance we'll remap your vehicle to get the maximum horsepower and torque

Fuel Economy Remaps

Better fuel economy mapping, this will save you money and can also increase performance too.

Additional Options

We offer DPF removal, EGR removal, speed limiter removal and rev limit removal.

Tuning options

Stage 1 ECU

Stage 1 ECU

A fully custom remap of your engine's software, written for your exact vehicle rather than pulled from a generic database. Expect noticeably sharper throttle response, stronger mid-range torque and smoother power delivery throughout the rev range. Safe within your engine's limits, fully reversible, and ideal as the first upgrade for any car or van.

From £199RRP £275
Stage 1 Transmission Tune

Stage 1 Transmission Tune

A custom recalibration of your DSG or automatic gearbox software. Shift points, clutch pressure and torque limits are all optimised, giving you faster, cleaner and more decisive gear changes. It pairs perfectly with an engine tune and transforms how the car feels in both manual and automatic modes.

From £199RRP £275
Stage 1 Package

Stage 1 Package

Engine & transmission

Our complete Stage 1 setup: a custom engine remap and gearbox calibration tuned together as one matched package. Because the engine and gearbox software are developed side by side, power delivery and gear changes work in perfect harmony. The best-value route to a car that pulls harder, shifts quicker and drives like a better-engineered version of itself.

From £350RRP £449.99
Stage 2 Transmission

Stage 2 Transmission

Built for vehicles with supporting hardware already fitted, such as a decat or downpipe and intake upgrades. We push the calibration much further than Stage 1, raising boost and fuelling to unlock the full potential of your modifications. Every Stage 2 file is written from scratch and road-tested, so the power gains come with a drivable, reliable result.

From £299.99RRP £549.99
