Mercedes & Chrysler Crossfire Bosch ME2.8 ECM Cloning — Mail-In Engine Computer Bench Service (~1998–2008)
Bolted in a used engine computer and now the Mercedes or Crossfire cranks but never catches? Mail in your original Bosch ME2.8 plus a part-number-matched donor and we clone the identity, immobilizer relationship, and calibration across on the bench so the donor installs plug-and-play with factory security intact.
Sending several modules? Add them all — one box, one return-shipping charge.

- Crossfire SRT-6 supercharged 3.2L (2005–2006)
- Mercedes R170 SLK platform underneath — same Bosch ME2.8 family
- Immobilizer partner on the Crossfire is the SKREEM, not a Mercedes EIS
What transfers on a clone
- ECM identity so the car accepts the donor as its own
- Immobilizer / drive-authorization relationship with the EIS or SKREEM
- Engine calibration and variant coding
- Stored adaptation values where readable
- Result: a used ECM that installs plug-and-play with factory security still active
Best for
- Failed original ECM being replaced with a second-hand unit
- Donor ECM already installed and the engine cranks without firing
- Water-, heat-, or corrosion-damaged ECM that still responds — clone it out before it dies
- Crossfire owners with no dealer path for a replacement engine computer
- Avoiding a dealer-only coded ECM order plus a tow
Not this service
- Crossfire keys and SKREEM work — see our Crossfire remote key and valet key services
- Mercedes EIS cloning or key programming — separate listings
- Immobilizer delete — we do not remove drive authorization on this listing
- Diesel CDI and V8 ECMs — different controller families, contact us to verify
- Internally dead ECMs — see our advanced ECU recovery service
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Used ME2.8 ECM installed and the engine cranks strongly but never fires
- Original engine computer failed and the dealer quote for a coded replacement is four figures
- Drive-authorization or start-error behaviour immediately after an ECM swap
- No communication with the engine ECM and you already have a donor unit ready
- Water, heat, or corrosion damage to an ECM that still responds — clone it before it dies completely
- Crossfire with a failed engine computer and no dealer replacement path
Won't fix:
- Does not include the donor ECM — you source a part-number-matched used unit and we verify it first
- Does not clone an ECM that is internally dead and will not power up or respond — see our ecu-advanced-recovery-service listing
- Does not remove or bypass the immobilizer — drive authorization stays fully intact
- Does not program keys or service the EIS or SKREEM — those are separate key services
- Does not fix a no-start caused by fuel, spark, sensors, crank position signal, wiring, or a flat battery
- Does not cover Mercedes V8, AMG M113-family, or CDI diesel ECMs under this listing — contact us to verify yours
- Does not bypass proof of ownership
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
The Crossfire is a Mercedes underneath — and the ECM knows it
Chrysler sold the Crossfire, but the platform is a Mercedes R170 SLK and the engine computer is the same Bosch ME2.8 family Mercedes used on the M112 V6. That means a Crossfire behaves exactly like a Mercedes when you swap the engine computer: the ECM is tied to the immobilizer partner in the car — a SKREEM here, an EIS on the Mercedes cars — so a donor unit cranks the engine and never lets it run. Cloning is the fix on both sides of the badge. It also means Crossfire owners are not stuck when a dealer has no answer: the bench path is the same one we use on a W203 or an R170. Proof of ownership is required for any immobilizer-related work.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Verify first: text or email us your VIN plus clear photos of your original ECM's label and the donor's label — a technician confirms the Bosch and Mercedes or Chrysler part numbers are a compatible match before you ship. Once verified, remove both units and ship them to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1009 Oakwood Ln # 120241, Arlington TX 76012 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box). We read, back up, and clone on the bench, test communication, and ship both back via the return option you pick at checkout (Standard $29.95, UPS 2-Day $54.95, or UPS overnight $94.95).
What to include in your box
- Your original ME2.8 ECM (it must still power up to be readable) AND the part-number-matched donor ECM
- Year, make, model, and engine (e.g. 2005 Chrysler Crossfire 3.2L, or 2003 Mercedes C320 3.2L V6)
- VIN of the vehicle
- Bosch number plus the Mercedes or Chrysler part number off BOTH ECM labels so we can pre-verify the match
- What is wrong now: original dead, cranks-no-start after a swap, no communication, water or heat damage
- Whether your keys currently work and whether the car has ever had EIS or SKREEM work done
- Proof of ownership (title, registration, or bill of sale) — required for all immobilizer-related work
- A clear photo of the ECM label, plus your name, return address, and email
