Mail-In PCM / ECU Unlock, IMMO-OFF or Clone — Any Supported Family, Bench Service
Locked, immobilizer-bound or unreadable PCM / ECU and the online calculator could not take your file? Mail the module — we unlock, IMMO-OFF or clone it on the bench and ship it back.
Sending several modules? Add them all — one box, one return-shipping charge.

The families behind the online calculators — Chrysler / Dodge / Jeep / Ram GPEC2 / GPEC2A, GM memcal VATS-OFF, BMW ME7.2 / MS43 / MS45, Bosch ME7 EEPROM — plus IMMO-OFF, checksum repair and clone work on the ECUs those calculators cover

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- The online calculator refused your file or the module cannot be read over OBD
- Tuning software cannot read or write the PCM (security-locked GPEC2 / GPEC2A)
- Immobilizer-bound ECU going into a swap, standalone or race build
- Used replacement PCM that needs to be unlocked or cloned to your car
- A patched file with a bad checksum that the ECU rejects
- No J2534 tool, no bench rig — you would rather mail the module
Won't fix:
- Emissions deletes (DPF / EGR / AdBlue / catalyst) — we do not perform them
- Odometer rollback — mileage sync only, never a rollback
- Remote flashing on your own J2534 — that is the remote session line
- Modules with no bench path (Global B / VIP GM, FBS4 Mercedes) — text us first if unsure
- Physically water-damaged or burnt boards — that is a repair job, ask before shipping
Shipping Instructions
These details are also emailed to you the moment your payment clears.
We buy and email you a prepaid inbound label, so shipping it to us costs you nothing. Return shipping is selected and paid at checkout — Standard $29.95 (3–5 days), UPS 2-Day $54.95, or UPS overnight $94.95. Ship the PCM / ECU only, in an anti-static bag with padding, with a note carrying your name, order number and what you need done.
What to include in your box
- The PCM / ECU / DME itself (no keys, no other modules)
- A note with your name, order number, ECU family, part number and the work you need
- Your original file on a USB stick if the online calculator rejected it (optional)
