MCCoding — technical reference

ECU cloning — bench read & write

Sheet: MCC-CLN-01
Scale: NTS

A clone only drives away when program, data and security areas all move across correctly.

Original / faulty unit: Your unit. Even a dead one usually still gives up its data on the bench.

Clone, don't guess

A 1:1 clone keeps your VIN, mileage and immobiliser data, so no dealer visit and no online coding fees.

Dead units still hold data

Water damage or a failed driver stage usually leaves the memory readable on the bench.

Checksums decide reliability

Every written file is checksum-corrected and read back — that verify step is what stops limp-mode surprises.

From £149, same-day options

Post it in or we come to you across the West Midlands; many units are turned around the same day.

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

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.

Wolverhampton & West Midlands

Do you cover bcm / ecu / tcu cloning in Wolverhampton?

Yes. Wolverhampton is our base. BCM / ECU / TCU Cloning is carried out mobile at your address or at the workshop, usually same or next day.

Which areas outside Wolverhampton do you travel to?

Mobile cover across the West Midlands — Birmingham, Walsall, Dudley, West Bromwich, Cannock and Telford. Modules and ECUs are also accepted by post UK-wide.

Are you an automotive electronics specialist or a general garage?

Automotive electronics only — keys, immobilisers, ECU cloning, coding and diagnostics. No bodywork, no guesswork.
