FAQs

ECU remapping is the process of modifying the software calibration within your vehicle’s Engine Control Unit (ECU). Adjusting parameters such as fuelling, ignition, boost pressure and torque limits can improve performance, throttle response and drivability. At Powerlab London, we use custom tuning solutions based on the individual vehicle and its requirements.

A Stage 1 remap is generally designed for standard or lightly modified vehicles and focuses on optimising the factory ECU calibration. Depending on the vehicle, this can provide improvements in power, torque and throttle response without requiring major hardware modifications.

A professionally developed calibration should take the vehicle’s condition and hardware into account. At Powerlab London, we carry out a health check before tuning and tailor the calibration to the vehicle. However, no vehicle modification is completely risk-free, and the condition of the engine, gearbox and other components is important.

The potential gains depend on the make, model, engine, existing calibration and any modifications fitted. Rather than promising the same figures for every vehicle, we assess your car and can advise you on the realistic improvements that may be achievable.

The time required varies depending on the vehicle, ECU and type of work being carried out. A straightforward remap can often be completed within a few hours, while more complex tuning, ECU unlocking or additional diagnostics may take longer. We will give you an estimated timescale when discussing your vehicle.

Yes. Powerlab London operates on a mobile basis, bringing our ECU tuning services directly to customers. We cover London, Surrey, West Sussex and surrounding areas, including Redhill, Reigate, Crawley, East Grinstead, Horsham, Epsom, Leatherhead, Guildford, Sevenoaks, Dorking, Woking and Royal Tunbridge Wells.

Yes. We believe checking the vehicle before tuning is an important part of providing a quality service. We carry out a health check to identify potential issues that could affect the tuning process and discuss any concerns with you before proceeding.

Yes. In many cases, we can create a calibration around a vehicle’s modifications. This is particularly important for Stage 2 and Stage 3 tuning, where hardware upgrades can significantly change how the engine operates. We will discuss your modifications and requirements before recommending a suitable tune.

The stages generally refer to the level of modification and tuning involved. Stage 1 is typically suitable for standard or lightly modified vehicles, while Stage 2 is usually designed around supporting hardware upgrades. Stage 3 is intended for more extensively modified vehicles and requires a calibration specifically suited to the vehicle’s setup.

Yes. We can tune many automatic and semi-automatic vehicles. In addition to ECU remapping, we offer TCU remapping, which modifies the software controlling the gearbox to optimise areas such as shift points, shift speeds and torque limits where supported.

TCU remapping involves modifying the software within the Transmission Control Unit. Depending on the vehicle and gearbox, this can improve shift response, alter shift points and increase available torque limits, complementing an ECU remap or providing improvements to the gearbox’s behaviour.

We offer speed limiter removal for suitable vehicles. The vehicle’s capabilities, tyres, mechanical condition and applicable legal requirements should always be considered before changing a manufacturer’s speed restriction.

Pops and bangs tuning modifies the ECU calibration to create additional crackles and pops from the exhaust during certain driving conditions, particularly on overrun. This is generally aimed at suitable performance vehicles and should be calibrated appropriately for the vehicle and exhaust system.

Yes. We offer start/stop removal on compatible vehicles by modifying the relevant ECU calibration so that the automatic start/stop function is disabled.

Yes, we provide specialist ECU solutions relating to DPF, EGR, AdBlue and OPF systems on compatible vehicles. These systems form part of the vehicle’s emissions-control equipment, so any modification must be considered in relation to applicable legislation and the vehicle’s intended use.

Modern ECUs can have security protections that prevent access to their calibration. ECU unlocking allows compatible ECUs to be accessed for tuning where the required security process is supported.
