The computer is connected via three connectors that pull out when a plastic clip is pressed. Remove the computer, and with a philips screwdriver remove the metal lid from the top of the computer. There may be small daughter circuit board covering some of the main circuitry.

Unscrew this and lift it out of the way. Honda ECUs run in generations, which use different connectors. Below is a stack of ECUs running from the newest generation at the top to the oldest generation at the bottom.

The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. Here is a list of common ECUs:.

The last 3 characters are broken down into 3 parts. There are other versions of this, but you get the idea. The second digit "0" typically means manual transmission, where a "5" means automatic transmission, and the last digit "1" is the version number.

This is usually a two or three digit number stamped on the 28 pin ROM, or main processor. Accord and Prelude ECUs can use a letter and number code.Skip to main content Honda ECU.

Hondata vs. Chipped ECU and How To Calibrate TPS Our Way

Not equivalent to a true dealer pass-through. Seems like a quality product, packaged well, prompt delivery, good instructions, had no difficulties installing. OBD error code cleared almost immediately, have had no recurrence after miles and several days. Exactly what I ordered!! Highly recommend. Jumper harness is good quality wiring easy to unclip off ecu if you need to. Perfect fitment, cheap price for what you get. Only 16 left in stock - order soon.

I love this tool and it fixed my idle problem after I replaced an electronic throttle body on my honda cr-v. I cant wait to learn more about what I can do with this tool. The harness is great quality and it's just plug and play, everything lined up and the car started up no problems.Honda is a Japanese company that is well known for manufacturing vehicles and motorcycles.

It is the largest producer of internal combustion engines in the world. It also produces luxury vehicles as well as race car vehicles for Formula One. The best way to give this vehicle an upgrade is by installing the Honda performance chips which are available for every single model of Honda.

These ECU chips help to increase the horsepower of the vehicle to a level that we may have once thought unattainable as well as improve its torque and overall performance. The Honda performance chips come with a knob that allows the driver to adjust the power for hauling or when trying to economize on fuel.

When you purchase this chip, you will be able to install it very easily as it will only require a few minutes, and the vehicle will be blazing the streets with more power than ever. Make Select Make. Model Select Model. Honda Home Search by Vehicle Honda. Choose Options Compare.

Briggs SF, CA.An engine control unit ECUalso commonly called an engine control module ECMis a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance.

It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps called lookup tablesand adjusting the engine actuators.

Before ECUs, air-fuel mixture, ignition timing, and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means. The fuel injection system has the major role to control the engine's fuel supply.

The whole mechanism of the EEMS is controlled by a stack of sensors and actuators. Most modern engines use some type of fuel injection to deliver fuel to the cylinders.

The ECU determines the amount of fuel to inject based on a number of sensor readings. Oxygen sensors tell the ECU whether the engine is running rich too much fuel or too little oxygen or running lean too much oxygen or too little fuel as compared to ideal conditions known as stoichiometric.

The throttle position sensor tells the ECU how far the throttle plate is opened when the accelerator gas pedal is pressed down. The mass air flow sensor measures the amount of air flowing into the engine through the throttle plate. The engine coolant temperature sensor measures whether the engine is warmed up or cool.

If the engine is still cool, additional fuel will be injected. Air—fuel mixture control of carburetors with computers is designed with a similar principle, but a mixture control solenoid or stepper motor is incorporated in the float bowl of the carburetor. Most engine systems have idle speed control built into the ECU. The engine RPM is monitored by the crankshaft position sensor which plays a primary role in the engine timing functions for fuel injection, spark events, and valve timing.

Idle speed is controlled by a programmable throttle stop or an idle air bypass control stepper motor. Early carburetor-based systems used a programmable throttle stop using a bidirectional DC motor. Early throttle body injection TBI systems used an idle air control stepper motor.

Effective idle speed control must anticipate the engine load at idle. A full authority throttle control system may be used to control idle speed, provide cruise control functions and top speed limitation. It also monitors the ECU section for reliability. Some engines have variable valve timing.

In such an engine, the ECU controls the time in the engine cycle at which the valves open. The valves are usually opened sooner at higher speed than at lower speed.
