Engine Control Module for GM and Pontiac ApplicationsCardone 77-7730 is a remanufactured engine control module built for specific GM compact and performance applications from the late 1980s through the early 1990s. It is engineered to restore factory-style engine management for vehicles such as the Chevrolet Cavalier, Chevrolet Camaro, Pontiac Firebird, and Pontiac Sunbird.This Cardone Engine Control Module line focuses on OE-style fit and validated electronic performance. For applications that use PROM or CALPACK components, those parts must be transferred from the original module during installation.Key Features Remanufactured Original Equipment-style ECM for direct-fit replacement Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant 100% computer tested for electrical function and reliability On-car validation is used to confirm durability and performance Earth-friendly remanufacturing process reduces raw material and energy use versus new part production Part number 77-7730 for application matching and service lookup Detailed DescriptionCardone 77-7730 is an Engine Control Module (ECM) remanufactured to meet or exceed OE performance expectations. The remanufacturing process is based on reverse engineering of failed units, which helps identify common design weaknesses and correct them during rebuild. That approach supports consistent operation in vehicles that rely on precise fuel, spark, and idle control.Compatible With 1987-1994 Chevrolet Cavalier, 1987-1993 Chevrolet Corsica, 1990-1992 Chevrolet Camaro, 1987-1990 Chevrolet Celebrity, 1991-1993 Pontiac Sunbird, 1990-1992 Pontiac Firebird, 1987-1991 Pontiac 6000, 1987-1989 Buick Century, 1987 Buick Skyhawk, 1987-1989 Oldsmobile Cutlass Ciera, 1987-1989 Oldsmobile Cutlass Cruiser, 1987 Oldsmobile Firenza, 1987-1988 Cadillac Cimarron. This part cross-references GM OE numbers such as 1227730 and Chevrolet service numbers including 16196344.What It Helps Resolve Engine no-start or intermittent start concerns tied to a failed ECM Rough idle, poor drivability, or unstable fuel control Electronic control faults caused by damaged solder joints or internal component failure Replacement needs after diagnosis confirms the original module has failed Service issues on vehicles requiring PROM/CALPACK transfer during ECM replacement Installation Notes and Tips Verify the original module part number and engineering ID before ordering. Transfer the PROM(s) or CALPACK from the original module when required by the application. Inspect grounds, power feeds, wiring harnesses, solenoids, and relays before installing the replacement ECM. Some vehicles may require additional relearns after installation, including theft, crankshaft, or idle procedures. Chrysler PCM units with a “V” suffix require VIN programming; Ford and GM anti-theft relearn procedures depend on the vehicle and system. Quality AssuranceEach Cardone remanufactured control module is computer tested, and many applications also receive bench testing or on-car validation to confirm operation. The brand’s remanufacturing process is built around correcting known failure points and restoring dependable electronic control for service use. Part number 77-7730 is backed by Cardone’s remanufactured OE-style construction and testing process.
