Have a failed, water-damaged, corrupted, or non-communicating GM E38 Engine Control Module (ECM)?

Lacorte Automotive offers a professional mail-in GM E38 ECM cloning and programming service. You send us your original E38 ECM and a compatible replacement E38 ECM. We transfer the applicable vehicle-specific data and configuration from your original module to the replacement, professionally bench test and verify the completed ECM, and return both modules to you.

YOU SEND BOTH E38 ECMs — WE PROGRAM THE REPLACEMENT

This listing does NOT include a replacement ECM.

YOU SEND:

• Original GM E38 ECM
• Compatible replacement GM E38 ECM
• Vehicle VIN
• Year / Make / Model

• Other supported GM applications

Applications may include vehicles such as select Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Corvette, Camaro and other GM models, depending on year, engine and ECM configuration.

COMMON E38 ECM FAILURE SYMPTOMS

A failing or damaged E38 may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine stalling
• Rough running / misfires
• Reduced engine power
• Limp mode
• No communication with ECM
• Intermittent communication
