Yes! This is the core benefit of our service. After you place your order, you provide us with your vehicle’s VIN. We then program the ECM with the latest GM software specific to your vehicle. It arrives at your door ready for installation, with no further programming required.
How do I provide my Vehicle Identification Number (VIN)?

Will this fix my check engine light?
If the check engine light is caused by a faulty ECM (e.g., internal processor error codes like P0606), this part is the correct solution. However, a check engine light can be triggered by hundreds of potential issues. We always recommend having your vehicle properly diagnosed by a qualified mechanic to confirm the ECM is the point of failure before ordering.
