Jeep Grand Wagoneer engine computers also known as the Engine Control Module (ECM) or the Powertrain Control Module (PCM) are electrical control units that all modern Jeep vehicles come equipped with. The ECM controls the fuel mixture, ignition timing, variable cam timing and stores all Diagnostic Trouble Codes (DTC). Once diagnosed properly, replacing the Jeep PCM through our service is as easy as it gets. Using your VIN, our technicians are able to program an OEM replacement unit that matches your vehicle's specifications. An updated Grand Wagoneer ECM ECU can result in better mileage, reduced pollution and overall handling of the car. Our units arrive plug & play, meaning little to no previous mechanical experience needed. All Grand Wagoneer engine computers leave our facility fully flashed and programmed to the latest engine control software updates provided by Jeep.

Example of a VIN number:

The vehicle identification number (VIN) refers to a unique code that is given to each Grand Wagoneer vehicle. The VIN acts as the car's fingerprint, as no two vehicles have the same number. A VIN is composed of 17 characters (digits and capital letters) that act as a unique identifier for the vehicle. Each character is used to reference the vehicle's unique features, specifications and manufacturer. VIN numbers can be used to track recalls, registrations, warranty claims, thefts and insurance coverage. In our case, the VIN is used to identify the correct module for a particular vehicle.

You can find the VIN (17 digit identification number) engraved at the bottom corner of the drivers side windshield or inside the drivers door. It can also be found on the title, registration or insurance card of the vehicle.

There is an I.D. sticker on the computer that will have the “service number”. This may be abbreviated like “serv. no.” or “service no.” etc. This will be followed by the number that is used for identification. In almost all cases if you provide your Vehicle Identification Number (VIN) we can identify the correct part/service number for your vehicle’s module.

Plug & Play or Plug ‘N Drive refers to all control modules that don’t require additional programming. Most units before 1996 (OBD I) are referred to as plug-n-play. All of our Jeep Grand Wagoneer engine control units are sold as Plug & Play.

This term refers to the programming process our mechanics perform on all specified control modules. During this process the Grand Wagoneer's replacement engine control module is VIN Programmed and flashed with the most recent manufacturer updates. These updates can help improve the performance and fuel economy of the vehicle.

Flagship One does not require any Core Charges or Core Returns. Many other control module suppliers charge users a fee to return their old unit. Keep this in mind when comparing prices with other sites.

Flagship One offers free shipping throughout the USA. There is a 1-3 day handling time after an order is place. We use USPS Priority shipping to deliver all of our modules. This usually takes 1-3 business days on average and most of our modules are delivered to the customer in less then 5 business days. In some cases we can expedite the shipping and will inform you if that is a possibility.
