Experiencing frustrating engine stalls, poor fuel economy, or a persistent Check Engine light that just won’t go away?

This VIN-programmed engine computer is your direct-fit, hassle-free solution to restore your vehicle’s original performance and get you back behind the wheel with complete confidence. We take the guesswork out of the repair by programming the module specifically for your car using your VIN before it even leaves our facility.

- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and rough idling.

An Expert’s Take on Programming
“In my 20 years of diagnostics, I’ve seen countless DIY repairs go wrong because of an unprogrammed module. People buy a used ECM online, plug it in, and nothing happens—or worse, new problems appear. That’s because the ECM is the ‘brain’ of your car; it’s tied to the security system, the transmission, and dozens of sensors. Our VIN-flashing service isn’t just a convenience; it’s the most critical step to ensure the repair is successful. We’re essentially giving your car its original brain back, but with all the latest software knowledge, so it works correctly the first time.”
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your car.
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, the location varies by model (e.g., in the air cleaner box, on the firewall). We always recommend consulting a repair manual for your specific vehicle. After installation, some vehicles may require a simple security or crankshaft position relearn procedure, which can often be done without special tools.
Will this fix my specific problem?
This programmed 12590032 ECM is a direct solution for a failed module. While it resolves the common symptoms listed above, it’s essential to ensure your vehicle has been properly diagnosed. Faulty wiring, sensors, or other components can sometimes mimic ECM failure. Proper diagnosis is key to a successful repair.
What does ‘interchangeable service numbers’ mean?
Automakers like GM often release updated versions of a part over the years. The different service numbers (e.g., 12590032, 12602044) represent these various revisions. Our module is compatible with all the listed service numbers, and we load it with the newest stable software available for your vehicle’s VIN.
Do I need to send my old ECM (core) back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
