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.
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 and waiting weeks for it to arrive, 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, towing to the dealer, and waiting weeks for backordered parts.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
Why wait 3 weeks for a backordered ECU from the dealer? We can take a used unit, clone your original data, and have your car running perfectly in under an hour. 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 September 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.
