Safety Precautions

Here are some very important safety precautions when testing the wires coming out of the 60 pin PCM connector.

1. If one or any of the wires on your Ford pickup DO NOT match the color stated in the pin out charts, then you should not use the pin out charts in this article. Why? Because this is the clearest indication that these ARE NOT the connector pin out charts for your particular Ford pickup.
2. Never probe the front of the connector.
   • You should use a wire piercing probe and probe the wire a few inches away from the connector.
     • To see what this tool looks like: Wire Piercing Probe.
   • You should use a back-probe.
3. You should never disconnect any of the PCM connectors without first disconnecting the battery negative (-) terminal.

These PCMs have been engineered and tested to meet Ford’s high standards for performance, reliability, and compatibility. The PCM in a Ford Ranger plays a critical role in managing the engine’s performance and various powertrain functions. It controls functions such as fuel injection, ignition timing, emission control systems, and other aspects of the engine’s operation. By choosing an OEM PCM for your Ford Ranger from Flagship One, you can have confidence in the quality and compatibility of the product. These PCMs are designed to work seamlessly with your Ranger’s engine and powertrain, ensuring optimal performance and efficiency.

Ford Ranger Engine Computers

If your Ford Ranger isn’t running as it should, a new Engine Computer may be just what you need. Flagship One has a wide selection of Engine Computers specifically designed for your Ford Ranger, so you’re sure to find the perfect one for your needs. Using the right Powertrain Control Module ensures that your Ford Ranger runs smoothly and produces fewer emissions. Here are 8 frequently asked questions and answers to help you understand the importance of this automobile component.

1. What does an Engine Computer do?

An Engine Computer, or Powertrain Control Module (PCM), is responsible for regulating the performance of your Ford Ranger’s engine. It monitors and controls many different aspects of engine function, including fuel delivery, ignition timing, and emissions.

2. Why is it important to use the correct engine computer?

Using the wrong engine computer can lead to decreased performance, poor fuel economy, and even damage to your Ford Ranger’s engine. The PCM is specifically calibrated for your vehicle’s engine and components, so it is essential to use the correct one to ensure optimal performance..

3. Can you get any year computer for your Ford Ranger?

Ford installs a new engine computer in each car model every year. The computer is designed to take information from sensors that are unique to each year and model of Ford Ranger. If you buy and install a computer for a different year, it may not work as well or may cause costly malfunctions. Luckily, engine computers for many years & models of Ford Ranger are readily availble from Flagship One.

4. How will a new engine computer improve the performance of my Ford Ranger?

If you install a new control unit in your Ford Ranger, you can expect a variety of improvements. This can include better fuel delivery and ignition timing, resulting in higher gas efficiency. Additionally, a new Ford Ranger PCM can help decrease emissions, making your vehicle compliant with environmental regulations.

5. What are some symptoms of a powertrain control module malfunction?

There are many symptoms of a faulty pcm, including poor fuel economy, the check engine light comes on, decreased performance, the engine stalls or misfires, rough idling, and increased emissions. If you experience any of these problems, it’s likely that your engine computer needs to be replaced.

6. Is an ECU and PCM the same thing?

PCM (Powertrain Control Module) — The PCM manages both the engine and transmission. It ensures that both the engine and transmission are working correctly.

ECU (Engine Control Unit) / ECM (Engine Control Module) — The control unit manages the engine only. It oversees all of the sensors, actuators, fuel injection, and ignition associated with the engine.

7. What is a programmed ECM?

A programmed ECM is an engine computer that has been pre-loaded with the specific calibration for your Ford Ranger. This can save you time and money, as you won’t have to take your Ford to a dealership or mechanic to have the computer flashed (a process of programming the computer to match your Ford’s engine). Flagship One offers pre-programmed engine control modules for a wide variety of Ford vehicles, including some units that are plug&play.

8. Are the Vehicle Identification Number (VIN) and ECM related?

The VIN on your Ranger is related to the specific ECM that your car needs. Ford will not release an engine computer without checking the VIN compatibility. The Engine Computers from Flagship One are all programmed to your Ranger’s year and model, so you don’t have to worry about finding the correct electronic control module. Simply enter your VIN when ordering, and we’ll do the rest. We also offer PCM repair for select models.
