Safe and precise cloning of ECU data for replacement units, fault recovery, and vehicle compatibility - ensuring your vehicle's engine management system is restored exactly as it should be.
When an ECU fails, gets damaged, or needs replacing, the data stored within it - your vehicle's entire engine management profile - is at risk of being lost forever. A replacement unit straight from a dealer comes blank, incorrectly coded, or mapped to an entirely different vehicle.
The result is a car that won't start, runs poorly, or throws endless fault codes. Broadway Remapping's ECU cloning service transfers your existing ECU data precisely and safely onto a replacement unit - restoring your vehicle to exactly how it was, without the dealership cost or the guesswork.


Whether your original ECU has failed electrically, been damaged, or simply needs replacing due to age or fault, our cloning service ensures the replacement unit carries an exact mirror of your original data. Every parameter, every calibration, every vehicle-specific setting is transferred accurately - so your vehicle starts, runs, and performs exactly as it did before.

A corrupted or partially failed ECU doesn't always mean the data is gone. Broadway Remapping uses specialist equipment to recover and rebuild ECU data from units that have suffered software corruption, failed flashing attempts, or electrical damage. Where others write the unit off, we dig deeper - recovering what can be saved and restoring your vehicle's engine management profile as completely as possible.

Fitting a second-hand ECU is a cost-effective solution - but only if it's correctly matched to your vehicle. An ECU from a different car will carry the wrong vehicle identification, immobiliser data, and calibration settings, leaving your vehicle unable to start or run correctly. Our compatibility cloning service transfers your vehicle's correct data onto the donor unit, making it fully compatible and ready to run - saving you significant cost without cutting any corners.

Immobiliser and vehicle identification correctly matched
Eliminates fault codes caused by mismatched ECU data
Significant cost saving over brand new dealer-supplied units
