Chevrolet ECU engine controllers – original replacement modules
A Chevrolet ECU engine controller, also called an ECM, engine computer or injection control unit, is responsible for managing essential engine functions. Depending on the vehicle and engine, it controls fuel injection, ignition timing, electronic throttle operation, turbocharger boost, exhaust gas recirculation, particulate filter operation and communication across the vehicle network.
ECUSale supplies tested replacement controllers for Chevrolet vehicles. The available range may include modules used in models such as the Chevrolet Captiva, Cruze, Aveo, Spark, Orlando, Lacetti and Epica. Stock changes regularly, and the suitability of every ECU must be confirmed from its complete part numbers and vehicle configuration.

Chevrolet Captiva 2.4 petrol engine ECU
The current Chevrolet range includes the 96842730 U9 / Bosch 0261208782 engine ECU for Chevrolet Captiva 2.4. This tested controller is supplied ready for programming and is intended for compatible vehicles fitted with the correct engine and electronic configuration.
Listed applications include selected versions of:
- Chevrolet Captiva 2.4 petrol from 2006 to 2011 with the Z24SED engine,
- Chevrolet Captiva FL 2.4 petrol from 2011 to 2015 with the A24XE engine,
- Opel Antara 2.4 petrol with compatible Z24SED or A24XE applications.
The ECU is not supplied as a simple Plug & Play replacement. After installation, it requires appropriate vehicle programming and immobiliser adaptation. Depending on the vehicle, this may be carried out using compatible diagnostic equipment such as Tech 2, MDI or GDS2.
Looking for a Chevrolet Captiva 2.4 ECU?
Compare both references—96842730 U9 and Bosch 0261208782—with the original module. Also check the engine code, hardware version and programming requirements before ordering.

Chevrolet and Opel ECU compatibility
Some Chevrolet vehicles share engines, platforms and electronic systems with selected Opel models. For example, certain Chevrolet Captiva and Opel Antara versions can use controllers from the same Bosch ECU family.
This does not mean that every module with the same casing or connector is interchangeable. Differences may exist in the engine code, emissions standard, gearbox, market specification, hardware revision and installed software. If you are searching for a module used in an Opel vehicle, see our Opel ECU engine controllers.
How to select the correct Chevrolet ECU
The replacement controller should be selected using all references printed on the original ECU label. The vehicle model, production year and engine capacity alone are not sufficient because several different controllers may have been fitted to the same model.
Before ordering, compare:
- the complete GM or Chevrolet OEM part number,
- the manufacturer reference, such as the Bosch number,
- hardware and software identifiers,
- engine type, capacity, output and engine code,
- petrol or diesel fuel system,
- emissions standard and market specification,
- manual or automatic gearbox configuration,
- immobiliser system and programming requirements.
The VIN helps identify the vehicle but does not replace the numbers taken directly from the old controller. A superseded or alternative part number should be verified before purchase.
Chevrolet ECU programming
A replacement Chevrolet ECU may need to be programmed with the correct vehicle software and matched to the immobiliser system. A controller described as ready for programming is not necessarily ready to start the engine immediately after installation.
Programming requirements vary according to the ECU family and vehicle generation. They may include:
- loading the appropriate calibration or operating software,
- writing the VIN,
- immobiliser or theft-deterrent relearn,
- configuration of the engine and gearbox variant,
- throttle or sensor adaptation,
- clearing faults and completing post-installation checks.
Programming should be carried out using suitable diagnostic equipment while a stable power supply is connected to the vehicle. Interrupting the procedure may corrupt the controller software.
Virgin, Plug & Play, IMMO OFF and cloned ECUs
The preparation method offered for a replacement module depends on the ECU type and the individual product listing:
- Ready for programming – the controller requires vehicle-specific programming and adaptation after installation.
- Virgin – previously stored vehicle data has been reset so the ECU can be assigned to a compatible vehicle using the appropriate procedure.
- Plug & Play – the controller is prepared for a specific vehicle to reduce the amount of work required after installation.
- Cloned ECU – compatible data is transferred from the original controller to the replacement module.
- IMMO OFF – immobiliser operation is disabled in a compatible ECU where this preparation is technically available.
These descriptions are not interchangeable. Always read the selected product page and confirm what information, files or original components are required.
Chevrolet ECU cloning
If the original engine controller can still be read, it may be possible to transfer its EEPROM, FLASH or processor data to a compatible replacement. Successful cloning can preserve information such as the VIN, immobiliser data, calibration and vehicle configuration.
A replacement module must still be compatible at hardware level. Copying data does not make an unrelated ECU suitable for the vehicle. Severe water damage, burnt circuitry or processor failure may also prevent a reliable read from the original controller.
Common symptoms of a faulty Chevrolet ECU
- the engine cranks but does not start,
- intermittent starting or unexpected stalling,
- no diagnostic communication with the engine controller,
- limp mode and reduced engine power,
- injector, ignition coil or electronic throttle faults,
- immobiliser or CAN communication errors,
- incorrect cooling fan operation,
- faults appearing after water ingress, a short circuit or voltage surge,
- no-start condition following interrupted ECU programming.
These symptoms do not prove that the ECU itself is faulty. Similar problems can be caused by damaged wiring, poor earth connections, relays, fuses, sensors, actuators, low battery voltage or another control module. The vehicle should be diagnosed properly before a replacement ECU is ordered.

FAQ – Chevrolet ECU engine controllers
Does a replacement Chevrolet ECU need identical part numbers?
The safest option is a controller with the same complete GM OEM and manufacturer references. Some alternative or superseded numbers may be compatible, but they must be verified together with the hardware, software and vehicle configuration.
Will a used Chevrolet ECU work after it is connected?
Usually not without preparation. A standard used controller normally retains the immobiliser and configuration data of its previous vehicle. It may need resetting, programming, cloning or another compatible preparation method.
Is the 96842730 U9 / 0261208782 Captiva ECU Plug & Play?
No. The listed Bosch controller is supplied ready for programming. It requires appropriate vehicle programming and immobiliser adaptation after installation.
Which engines use the Bosch 0261208782 ECU?
The product is listed for selected Chevrolet Captiva 2.4 petrol vehicles with Z24SED or A24XE engines and for compatible Opel Antara 2.4 applications. The full numbers and vehicle configuration must still be checked.
Can an Opel Antara ECU be used in a Chevrolet Captiva?
Some Captiva and Antara versions share compatible engines and ECU hardware, but compatibility is not automatic. Check the GM and Bosch references, engine code, hardware version and software requirements before purchase.
Can a damaged Chevrolet ECU be cloned?
It may be possible if the required memory data can still be read from the original controller. If the electronics or processor are severely damaged, another programming or preparation method may be necessary.
Does a no-start condition always mean the Chevrolet ECU is faulty?
No. A no-start fault can also result from the immobiliser, battery voltage, wiring, sensors, relays, fuel supply or another module. Diagnostic testing should be completed before replacing the ECU.
What information should I send before ordering?
Send a clear photograph of the complete ECU label, the VIN, vehicle model and year, engine capacity and code, gearbox type, fuel type and any diagnostic fault codes.
