Have a failed, damaged, water-damaged, corrupted, or non-communicating GM E80 Engine Control Module (ECM)?

You send us your original E80 ECM, and we provide a compatible remanufactured E80 replacement ECM. We transfer the applicable vehicle-specific data and configuration, professionally program and bench test the replacement, and return it ready for installation where supported.

SUPPORTED GM APPLICATIONS

Supported applications may include select:

• Chevrolet

• Buick
• Cadillac
• Other supported GM applications equipped with the E80 ECM

Exact compatibility depends on the GM service number, part number, hardware/software version, engine, transmission/application, model year, production date, and vehicle configuration.

COMMON E80 ECM FAILURE SYMPTOMS

A failing E80 may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine stalling

• Injector-related faults
