Cardone 77-7747 Engine Control Module
Restore engine management performance with the Cardone 77-7747 Engine Control Module, a remanufactured ECM built to meet or exceed original equipment operation. This unit is a direct-fit replacement for select Chevrolet and GMC trucks, vans, and SUVs from 1987-1993, including applications such as Chevrolet C1500, GMC K2500, and Chevrolet Blazer.
Key Features
- Remanufactured Original Equipment-style ECM for proper vehicle fit
- Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant
- 100% computer tested for functionality and reliability
- On-car vehicle validation is used to evaluate durability and performance
- Reverse-engineered to identify and correct original design weaknesses
- Earth-friendly remanufacturing process reduces raw material and energy use versus new part production
Product Details
Cardone’s Engine Control Module line focuses on restoring factory-level control of fuel, ignition, and drivability functions. Part number 77-7747 is engineered for direct replacement in a wide range of GM applications, including 1987-1993 Chevrolet and GMC models. This ECM cross-references Chevrolet and GMC 1227747 for the same application. For fitment-based searches, this module is commonly selected for 1988-1993 Chevrolet C1500, 1987-1991 GMC Jimmy, and 1990-1991 Chevrolet S10 applications.
Because many of these vehicles use removable calibration components, PROMs/CALPACK must be transferred from the original module to the replacement on listed applications. Additional relearns such as theft, crankshaft, or idle procedures may also be required depending on the vehicle and service history. The Cardone 77-7747 is built for buyers who need a remanufactured ECM for older Chevrolet and GMC platforms with OE-style electronic control.
What This ECM Helps Resolve
- Hard starting or no-start conditions tied to ECM failure
- Erratic idle, stalling, or poor drivability
- Fuel and ignition control faults caused by a failed control module
- Intermittent electrical operation from weakened solder joints or internal components
- Replacement needs after diagnosing a failed original ECM
Installation Notes
- Verify the original module part number and engineering ID before ordering.
- Inspect grounds, power feeds, wiring harnesses, relays, and solenoids before installation.
- Transfer PROM(s)/CALPACK from the original module where required by the application.
- Perform any necessary relearns after installation, including theft, crankshaft, or idle procedures.
- For Chrysler, Ford, and GM anti-theft or programming questions, follow OE service procedures for the specific vehicle.
Quality Assurance
Each Cardone remanufactured ECM is computer tested, and application-specific units are validated on the vehicle for durability and performance. The remanufacturing process is designed to correct common failure points while returning the module to dependable service for Chevrolet and GMC applications. Part number 77-7747 is built to support OE-level operation in the vehicles listed above.
