Have a failed, damaged, corrupted, water-damaged, or non-communicating GM E98 Engine Control Module (ECM)?

You send us your original E98 ECM and a compatible replacement E98 ECM. We transfer the applicable vehicle-specific data and configuration from your original module to the replacement, professionally program and bench test it, and return both modules to you.

YOU SEND BOTH E98 ECMs — WE PROGRAM THE REPLACEMENT

THIS LISTING DOES NOT INCLUDE A REPLACEMENT ECM.

YOU SEND:

• Original GM E98 ECM
• Compatible replacement GM E98 ECM
• Vehicle VIN
• Year / Make / Model

SUPPORTED GM APPLICATIONS

The E98 ECM is found in select GM diesel applications. Supported vehicles may include certain:

• Chevrolet Silverado HD
• GMC Sierra HD
• Chevrolet Express
• GMC Savana
• Other compatible GM diesel applications using an E98 ECM

Applications can vary by model year and Duramax engine configuration, so compatibility should be verified using the original module numbers before ordering.

COMMON E98 ECM FAILURE SYMPTOMS

A faulty E98 may potentially cause:

• Crank but no start
• Intermittent no-start
• No communication with ECM
• Intermittent communication
• Engine stalling
• Reduced engine power
• Limp mode
• Rough running
• Injector-related faults
• Sensor circuit faults
• CAN/network communication faults
• Multiple unrelated DTCs
• Internal ECM processor faults
• Corrupted software/calibration data
• Water or moisture damage
• Completely non-responsive ECM

Proper diagnosis is strongly recommended. Wiring, grounds, power supplies, sensors, fuel-system components, network faults, and other vehicle systems can produce similar symptoms.

WHAT'S INCLUDED

• Original E98 data extraction
• Replacement E98 programming
• VIN configuration
• Vehicle-specific configuration transfer
• Software/calibration transfer where applicable
• Applicable ECM data transfer

HOW IT WORKS

1. YOU SEND

Ship us your original E98 and compatible replacement E98.

2. WE READ

We extract the applicable vehicle-specific information from your original ECM.

3. WE PROGRAM

Applicable original data and configuration are transferred/prepared for your replacement E98.

4. BENCH TESTED & VERIFIED

The completed replacement ECM is professionally bench checked and verified.

5. WE SHIP IT BACK

Both E98 ECMs are securely packaged and returned.

6. YOU RECEIVE

Your original E98 + programmed replacement E98 ECM.

PLUG & PLAY WHERE SUPPORTED

Our goal is to return your replacement E98 prepared for installation in the original vehicle with the applicable configuration transferred.

Certain applications may still require vehicle-side setup or relearn procedures.

TYPICAL 1–2 BUSINESS DAY TURNAROUND

Typical turnaround is 1–2 business days after receiving both modules, subject to module condition and compatibility.

Same-day rush service may be available.

IMPORTANT — REPLACEMENT COMPATIBILITY

Two E98 ECMs that physically look identical are not necessarily interchangeable.

Compatibility may depend on:

• GM service number
• GM part number
• Hardware number
• Software/calibration
• Engine
• Transmission/application
• Model year
• Vehicle configuration

NOT SURE IF YOUR E98 WILL WORK?

Send us clear photos of the labels on your original and replacement E98 ECMs, along with:

VIN • Year • Make • Model • Engine

We'll help verify compatibility before you ship.
