Hidden inside every modern car is an advanced computer that constantly orchestrates the operation of the entire powertrain. We are talking about the engine control unit, commonly known as the ECU (Engine Control Unit) or ECM (Engine Control Module). This specific module decides on the fuel injection dose, ignition timing, boost pressure, and communication with other systems in the vehicle.

Engine computer removed from a car intended for recycling with data saved from the previous car and immobilizer. To use this controller it is required to unlock it and then perform the programming procedure. For this purpose, it is necessary to use specialized diagnostic equipment for electronics.
2.Unlocked: There are many variants of the possible unlock device , so please contact us before purchasing because, depending on the type and model of the car or controller itself make some unlocking options not possible.
The controller can be prepared for assembly by our electronics in various ways: the list below
a) ECU with read PIN code (CAR PASS) - Required programming by diagnostic device. After the assmbly of the ecu to the car you need to reset that controller by typing in the pin code, and then performing the procedure of programming the immobilizer to your car
b) Cleaned Ecu out of the data of the previus car (VIRGIN). The ECU is reset to factory settings, prepared as clean. After installation in the car, it requires programming by using a specialized diagnostic device (STANDARD Unlocking of most of our ECUs if not specified the unlocking form)
c)Plug & Play (IMMO OFF) - excluded immobilizer, it has removed the safety codes from the ecu. Once its connected ecu to the car the engine runs and it does not require any programming, but it does not have the immobilizer function. - No need additional programming
d) Plug & Play (AUTO PROGRAMMING) - after assembly the ecu in the car, ECU will automatically program itself to your car. Does not require any programming
e) Plug & Play (CLON) - a cloned controller prepared for installation in a car without the need for programming. This device is copied 1 to 1 from the old device and the data is transferred to another properly working computer by our electrician service technician
Have to send us the damaged driver from which the data will be transferred to another, properly working computer.
Broken ecu HAS to have working communication with the car or diagnostic device , without proper communication Security code cant be cloned.
3.Complete: Plug & Play complete set ecu with immobilizer and all elements needed to start the vehicle without need for additional programming. Have to replace all the elements sent by us in your car.
