Clone, virginise, read & write — engine, gearbox & body modules.
Coding / Programming
BCM / ECU / TCU Cloning
Bench-grade cloning of Body Control Modules, Engine ECUs and Transmission Control Units. 1:1 EEPROM + flash copy so donors drop in without dealer coding.
Overview
For failed BCMs, corrupted TCUs and dead ECUs we bench-clone your original module to a hardware-matched donor. VIN, immobiliser sync, mileage and learned adaptations remain intact — no online dealer session required.
What's included
- Bench / boot-mode read
- 1:1 EEPROM + flash write
- Donor sourcing service
- Checksum & VIN verification
- Immo-off variant available
- Postal turnaround UK-wide
Step-by-step
- Step 1Module removal
Faulty BCM / ECU / TCU removed and bench prepped with correct pinout.
- Step 2Read
EEPROM + flash extracted in bench or boot mode with a stable power supply.
- Step 3Clone
1:1 write to hardware-matched donor, checksums verified.
- Step 4Test & dispatch
Bench-tested for comms and start-enable before return to vehicle.

Cloning from £180 per module, donor sourcing quoted separately. See price guide for details.
Frequently asked questions
What's the difference between ECU, BCM and TCU cloning?
ECU = engine control, TCU = transmission control, BCM = body control. All are cloned 1:1 so the replacement module drops in without coding.
Can you clone a locked module?
Yes — most modules can be read in bench or boot mode even when they refuse OBD comms, using CPU or bootloader access.
Do adaptations transfer?
Yes. Full EEPROM + flash cloning keeps learned data, VIN and immobiliser sync intact.
Do you supply donor modules?
Yes — donors sourced by hardware and software number, matched to your VIN and cloned before dispatch.
