Porsche Boxster ECU Clone Service

What this service is

A Porsche Boxster ECU clone is the fastest path back on the road when the original DME has failed. Instead of sourcing a new Bosch unit through Porsche parts and then paying the dealer for PIWIS immobilizer alignment and component protection pairing, we read your original DME’s complete memory, clone it onto a matched donor, and send it back ready to plug and 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.

Porsche Boxster DME platforms by generation

• 986 Boxster (1997–2004) — Bosch ME7.8 (2.5, 2.7, 3.2 S), earlier Siemens MS2.10
• 987 Boxster (2005–2012) — Bosch ME7.1.1 (base 2.7, S 3.2 and 3.4), Bosch ME9.1 (facelift 2.9 and 3.4 DFI, including Spyder and R)
• 981 Boxster (2013–2016) — Bosch MED17.1.1 / MED17.1.11 (2.7 and 3.4 DFI, including GTS and Spyder 981)
• 982 718 Boxster (2017–present) — Bosch MED17.8.10 (2.0/2.5 flat-four turbo), Bosch MDG1 (4.0 flat-six on Boxster Spyder RS / 25 Years / GTS 4.0)

Common Boxster part-number prefixes

Porsche DME part numbers follow the format 98x 907 xxx xx where “98x” is the platform (986, 987, 981, 982). Bosch hardware codes (0 261 S0x xxx, 0 261 S2x xxx) appear on a separate sticker. Matching both the Porsche part number suffix (AA, AB, AC for hardware revision) and the Bosch code is critical — a seemingly identical part number with a different suffix won’t start the car without coding work.

How the Boxster clone works

1. 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.
2. 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.
3. 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.
4. 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.
5. We clone onto your donor — your donor is blanked, then your original’s flash and EEPROM are written one-for-one.
6. Bench verification — every clone is simulated before it ships. Immobilizer bytes, VIN string, and odometer confirmed to match.
7. We ship your cloned donor back — 24-hour turnaround from when both units arrive. Plug in, turn the key, drive.

What’s preserved

• Immobilizer ISN → existing Porsche keys still work, no re-alignment
• Component protection → Boxster cluster, PCM, and Porsche Stability Management stay synced
• VIN stored in DME matches chassis VIN
• Mileage, throttle adaptation, Vanos / VarioCam timing learn
• Tune state if the original DME carried an aftermarket map
