GM E-Series ECM/PCM Cloning — Mail-In Bench Clone to a Donor (VIN, Calibration & Anti-Theft Carried Over)
Dead GM engine computer, or a used-ECM swap that cranks but won't start with a "theft" light? Mail in your original plus a matching donor and we clone your ECM/PCM onto it on the bench — VIN, calibration, and the anti-theft/VATS relationship carried over — so the replacement is plug-and-play with no dealer SPS trip.
Sending several modules? Add them all — one box, one return-shipping charge.
GM E-series ECM/PCM, Global A era (~2005–2018): E38 (Gen IV LS 5.3/6.0 trucks, SUVs, Camaro), E67 (supercharged LSA/LS9 and the FWD LS4 5.3 cars), E39/E39A (3.0/3.6 direct-injection V6 — Camaro V6 2010–2015, CTS/ATS/SRX, Equinox/Terrain), E37/E37A (3.5 / 3.9 / 4.3), E78 (2.0T / 2.4L / 1.4T Ecotec), E80/E82/E83/E84 (Ecotec GDI cars — Aveo, Cruze, Sonic) and E92 (Gen V LT 5.3/6.2, Corvette C7, Camaro). Donor must match the controller family and part number. Global B (2019+) is NOT bench-cloneable. Verified by VIN + module label before you ship.

NOT covered / not bench-cloneable
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Original ECM/PCM is dead or intermittent and you have a matching used donor to clone onto
- ✓No-comms — the module won't respond to a scan tool and the engine won't start
- ✓Used-ECM swap cranks but won't start because the box still belongs to the donor car
- ✓"Theft" / security light after installing a used ECM from another vehicle
- ✓You want to avoid a dealer SPS programming appointment for a replacement module
- ✓Replacement module needs your VIN, tune, and anti-theft data to run your car
Won't fix:
- ✗Does not clone Global B (2019+) GM controllers — no bench clone path exists
- ✗Does not clone a completely dead or unreadable original (there is nothing to copy)
- ✗Does not work when the donor doesn't match the controller family / part number
- ✗Does not repair internal ECM hardware damage (water, blown driver, cracked board)
- ✗Does not fix a no-start caused by fuel, spark, wiring, ground, or sensor faults
- ✗Does not add or program keys, and does not delete or bypass the immobilizer
- ✗Does not tune, add power, or modify emissions equipment in any way
Why a used ECM cranks but won't start — and how the clone fixes it
A used GM ECM you buy still carries the donor vehicle's VIN and anti-theft relationship, so when you install it the engine cranks but won't start and the "theft" light comes on — the module simply doesn't belong to your car. The dealer answer is an SPS programming appointment. Cloning does the opposite: we copy YOUR original module's identity — VIN, calibration, and the VATS/Passlock/immobilizer data — onto the matching donor on the bench, so the donor becomes a true drop-in for your vehicle. Reinstall it and it runs. The donor must match the controller family and part number, and your original must be readable for us to copy it. This is not a tune, not an unlock, and not an immobilizer delete.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Verify first: text or email us your VIN and both module service / part numbers (your original and the donor) and we confirm the donor matches your controller family and that your original is bench-readable before you ship anything — Global B (2019+) controllers are excluded, and a completely dead original cannot be cloned. Once verified, remove the module and ship it 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 clone your data onto the donor on the bench, test communication, and ship it back via the return option you pick at checkout (Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95).
What to include in your box
- Your ORIGINAL ECM/PCM (the one that runs your car / holds your VIN and tune)
- The matching DONOR ECM/PCM (same controller family and part number)
- Year, make, model, and engine size (e.g. 2012 Chevrolet Silverado 1500 5.3L)
- VIN of the vehicle
- The ECM/PCM service number / part number off BOTH case labels
- What is wrong now: dead module, no-comms, cranks-no-start, or a theft light after a swap
- Whether any other tuning has already been applied to the original ECM
- A clear photo of both module service-number labels, plus your name, return address, and phone
