Mobile ECU, ECM and PCM programming
and cloning in metro Atlanta
A dead engine computer does not always mean a new one. Where the original still holds readable data, we clone it.
Auto Module Programming reads the original module, writes it to a part-number-matched donor, and programs by VIN on the manufacturer software. Mobile ECM and mobile PCM work happens at your vehicle, across Georgia.
ECM programming in metro Atlanta typically costs $250–$550, depending on the vehicle and whether the module is new, used or cloned. Auto Module Programming programs and clones engine computers at your location with Factory OEM software, and most jobs are finished in about 2 hours. Call (404) 812-8951.

Told the engine module
has to be replaced?
Read it first.
A scanner reporting these codes is usually where a vehicle gets quoted a new virgin computer. It is often the wrong call, and not because anyone is being dishonest — a module that has stopped answering over OBD-II cannot be read by a scan tool, so a shop without bench equipment has nothing left to try.We read it on the bench, where it still answers.
Code P0601
Internal Control Module Memory Checksum Error.
Code P0606
ECM/PCM Processor Fault.
Our Solution
Instead of spending a fortune on a new module, we extract the critical data from your damaged unit (VIN, Immobilizer, Calibrations) and transfer them to a used or remanufactured unit.
The result: Your car starts immediately, with no additional programming needed at the dealer.
What cloning does that a new module does not
Buying a new ECU often requires expensive "Virgin" units and towing to the dealer.Cloning is faster, cheaper, and smarter.
Plug & Play
No need for additional programming at the dealer. Install and start.
Data Retention
We keep your VIN, Mileage, and Immobilizer security codes intact.
OEM Precision
Exact 1:1 copy of your original software and calibrations.
Your data, not a blank module
Your VIN, option configuration and theft-deterrent data carry across, so the vehicle network accepts the donor as the module it already knew.
Bench Programming
Where a module no longer answers over OBD-II, we read its flash and EEPROM directly on the bench with a VVDI Prog — which is what makes a clone possible on a unit the vehicle has already given up on.

Before you buy a
replacement controller
We can take a used unit, clone your original data, and have your car running. A straightforward clone takes 1–3 hours. Same warranty, fraction of the price.

What this costs
ECU / ECM / PCM programming by VIN
$250 – $550
Covers the diagnosis, programming the controller to your VIN on the manufacturer software, writing the option configuration, the post-programming relearns the platform calls for, and a post-scan of every module.
Confirmed October 2026 · before travel
Auto Module Programming publishes this band rather than quoting only on the phone. What moves it inside the band is whether your original controller still reads. If it does, cloning it to a matched donor is usually the cheaper route and skips the security procedure entirely. If it does not, the replacement has to be programmed from scratch and the immobilizer and key work is priced separately on top.
Before any of that we confirm the controller is actually the fault, because most of the units sent to us as failed are not. Give Auto Module Programming the year, make, model and VIN and we will tell you which of the two routes your vehicle is on, on (404) 812-8951
GM engine and transmission controllers
The part number on the controller label decides which of the three routes below applies to your vehicle. These are the ones we are asked about most:
Engine controllers. Transmission side: T87 and T87A.
Send us the part number and the VIN before you buy a used controller. A unit that looks identical and carries a different hardware revision will accept the data and then behave incorrectly, which is harder to diagnose than a module that refuses it outright — and it is the most common reason a customer-supplied controller cannot be used.
Your original still reads — clone it
The controller is read, and its contents written to a part-number-matched donor. Your VIN, your RPO configuration and your theft-deterrent data go with it, so the vehicle network accepts the donor as the module it already knew. This is the route that avoids a security relearn entirely.
Your original is gone — program the replacement by VIN
A new or used controller is programmed to your VIN on the manufacturer software, the RPO configuration is written so the controller knows which options the vehicle actually has, and the security and key procedure is completed under NASTF VSP credentialing with verified ownership.
The controller stopped answering — find out why first
A GM controller that has gone silent sets a lost-communication code, and that code is as often a ground or a CAN fault as a failed module. We test power, grounds under load and CAN High and CAN Low integrity before condemning anything. See how we handle U0100 and its relatives. The full sequence is here.

Questions people ask
Can I put a junkyard ECM in my Chevy without programming it?
Almost certainly not. A used ECM carries the donor car’s VIN and won’t match your Chevy’s immobilizer (Passlock/Passkey) — the engine will crank but not start, or start and stall. The module must be programmed to your VIN with a theft-deterrent relearn, using the exact same part number. We program and clone used ECMs on site across Metro Atlanta, and in Savannah, Augusta, Macon and Columbus by arrangement. Call (404) 812-8951, Mon–Sun 8am–7pm.
I need a mobile mechanic who can program an ECU in Georgia, not a shop
That’s exactly what we do. Auto Module Programming is a 100% mobile ECU/ECM programming service covering Metro Atlanta and, by arrangement, Savannah, Augusta, Macon, and Columbus. ECU programming, cloning, and flashing on site — typically $250–$550, before travel. No shop visit, no tow. (404) 812-8951, Mon–Sun 8am–7pm.
Can a mobile mechanic program modules as well as the dealer, or should I take the car in?
A qualified mobile programmer with dealer-level tools programs modules exactly as well as the dealer — same J2534 pass-thru, same OEM software, same procedure. The location doesn’t change the software. Take it to the dealer only for factory warranty, recalls, or modules locked to manufacturer servers. Security work such as keys and immobilizers we do ourselves, under NASTF VSP credentialing. Our mobile lab carries the manufacturer software for Ford, GM, Chrysler, Dodge, Jeep, RAM, Toyota, Honda, Nissan, Hyundai, Kia, BMW, Mercedes-Benz, Volkswagen, Audi, Mazda, Subaru and Mitsubishi: (404) 812-8951.
How much does ECM programming cost?
ECM programming runs $250–$550 in metro Atlanta, before travel. What moves it inside the band is whether your original module still reads. If it does, cloning it to a part-number-matched donor is usually the cheaper route and skips the security procedure entirely; if it does not, the replacement is programmed from scratch and the immobilizer and key work is priced separately on top. Call (404) 812-8951, Mon–Sun 8am–7pm.
Can a used ECM be programmed to my car?
Usually yes, provided the full OEM part number and the hardware revision match your vehicle exactly. A used ECM carries the donor car’s VIN and security data, so it has to be programmed to your VIN with a theft-deterrent relearn before the engine will start and stay running. Send us the part number off the module and your VIN before you buy it and we will tell you whether it matches, at no charge.
Do you come to my location?
Yes. Auto Module Programming is mobile: we program at your home, office or shop across Fulton, DeKalb, Gwinnett, Cobb and Cherokee counties, within 40 miles of Brookhaven, Georgia, and in Savannah, Augusta, Macon and Columbus by arrangement. We bring the Factory OEM software, the J2534 interface and the regulated supply to the vehicle, so there is no tow to pay for. Call (404) 812-8951, Mon–Sun 8am–7pm.
