What this service is
A Mitsubishi ECU clone removes the MUT-III / MUT-III-SE scan-tool step from a failed-ECM swap. We read your original ECU’s complete memory — flash plus the secured EEPROM holding immobilizer data, VIN, kilometers, and all learned values — write it to a matched donor, and ship it back ready to start.
Clone-only service — you supply both ECUs. This service requires two units: your failed original ECU and a matching donor ECU (same manufacturer part number and hardware revision), both supplied by you. We clone your original’s data onto your donor and ship it back. Not sure which donor matches? Email us a photo of your failed ECU label first and we confirm compatible part numbers before you buy a donor.
How to source a compatible donor
The donor does not need to come from a car with the same VIN or mileage — after cloning it carries your original data. What it does need to match exactly:
- Same manufacturer part number on the label
- Same hardware revision suffix (AA / AB / AC, or PCB rev number where printed)
- Same Bosch / Continental / Delphi / Denso hardware code where applicable
Good donor sources: eBay Motors, Car-Part.com, local salvage yards with parts-lookup, and make-specific forums / Facebook groups. Send us the label photo before you buy and we’ll pre-clear it.
Mitsubishi ECU platforms we support

- Mitsubishi 1860Axxx / 1860Bxxx / 8631A00x — family of part-number series across modern petrol platforms
USA-market Mitsubishi models covered
- Outlander, Outlander PHEV (2007–present)
- Outlander Sport / ASX (2011–present)
- Eclipse Cross (2018–present)
- Mirage, Mirage G4 (2014–present)
- Lancer, Lancer Evolution (2001–2017)
- Galant, Endeavor, Raider, Montero, Eclipse, 3000GT, Diamante, i-MiEV (legacy)
Common part-number prefixes
Mitsubishi ECM labels carry 1860xxxxx or 8631Axxx part numbers plus the Bosch hardware code on Bosch-supplied units (0 261 S0x xxx, 0 281 0xx xxx). We match those plus PCB revision before writing the clone.
How the clone works
- Email us the label first (recommended). Send a photo of your failed ECU’s part-number label and we confirm the exact donor part numbers that will work — before you spend money on a donor.
- You source a matching donor. Buy a compatible used ECU yourself through eBay Motors, Car-Part.com, or a salvage yard with parts-lookup. Must match manufacturer part number and hardware revision.
- Mail us BOTH units together — your failed original ECU AND the matching donor you sourced, shipped in the same box with your order number. Prepaid return label available on request.
- We bench-read your original — full flash plus EEPROM (immobilizer secret, VIN, mileage, learned values) captured intact. Most “dead” units can still be read on the bench.
- We clone onto your donor — your donor is blanked, then your original’s flash and EEPROM are written one-for-one.
- Bench verification — every clone is simulated before it ships. Immobilizer bytes, VIN string, and odometer confirmed to match.
- We ship your cloned donor back — 24-hour turnaround from when both units arrive. Plug in, turn the key, drive.
What’s preserved
- WIN / immobilizer pairing — existing keys and fobs still work
- VIN — cluster and SST transmission controller stay synced
- Mileage, idle learn, throttle adaptation, DPF regen history (diesel)
Pricing and warranty
$200 flat. Clone work only — donor ECU must be supplied by you. Nationwide mail-in. 24-hour bench turnaround. 12-month warranty. Send a photo of the ECM label with part number plus your Mitsubishi’s year and engine code — we confirm compatibility first.
