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

Your original ECU is read in bench or boot mode with a stable power supply, full EEPROM and flash are backed up, and the data is written 1:1 to a hardware-matched donor. Immobiliser sync, mileage and learned adaptations remain intact.

What's included

Bench / boot-mode read
Full EEPROM + flash backup
1:1 write to donor
Checksum verification
Ignition simulation test
Pre-flight before dispatch

Frequently asked questions

What is ECU cloning?

ECU cloning copies EEPROM and flash data from your original ECU to a replacement unit so the vehicle starts and runs without dealer synchronisation.

Do I need to send my ECU?

Yes — bench cloning gives the cleanest result. We accept postal ECUs UK-wide and return them tested.

Will DTCs, mileage and adaptations transfer?

Yes. EEPROM and flash are cloned 1:1 so learned data, mileage and immobiliser sync stay intact.

Which ECU brands do you clone?

Bosch EDC15/16/17, MED/MEDG, Siemens/Continental SIM, Delphi, Marelli, Denso and more. Check the ECU coverage page for the exact list.
