Can you program a used ECU or TCU to my car?
Yes. We specialise in programming used modules to your vehicle. The donor ECU/TCU is virginised (reset to factory state), then your vehicle's immobiliser data, VIN, and security information is programmed to it. This allows a used module to work exactly like a new one—but at a fraction of the cost.
What if my original ECU/TCU is completely dead?
If your original module is not readable, we can still program a replacement in most cases. For some vehicles we can extract security data from other modules (like the EIS/CAS/BSI), use dealer-level online coding, or use alternative methods depending on the manufacturer and security system.
How long does ECU or TCU data transfer take?
Most jobs are completed same-day or next-day depending on complexity. Simple cloning jobs may only take a few hours. More complex work involving FBS4, bench programming, or extensive diagnostics may take 1-2 days. We'll give you an accurate timeframe when you contact us.
Do I need to send my ECU/TCU to you, or can you do it mobile?
We offer both options. For local customers in Derby, Nottingham, Ilkeston, and surrounding areas, we can often perform the work mobile at your location. For more complex jobs or customers further away, modules can be sent to our workshop for bench programming and testing.
Which manufacturers can you work with?
We specialise in Mercedes-Benz (FBS3/FBS4), BMW (CAS/ISN), VAG Group (Audi/VW/SEAT/Škoda), Jaguar Land Rover, and PSA (Peugeot/Citroën). We also work with Ford, Renault, Nissan, Honda, Toyota, and many other makes. Contact us with your vehicle details and we'll confirm compatibility.
Is ECU/TCU cloning legal?
Yes, absolutely. Data transfer and cloning of control modules is a legitimate repair technique used worldwide. It's no different from any other vehicle repair—you're simply transferring your own vehicle's data from a failed module to a working replacement. This is standard practice in the automotive repair industry.
Will my warranty be affected?
If your vehicle is still under manufacturer warranty, using non-genuine parts or non-dealer programming may affect warranty coverage for related components. However, if your vehicle is out of warranty (most vehicles over 3 years old), there is no issue. We recommend checking your warranty status before proceeding.
