This ECU socketing guide has been provided to assist you with your ECU socketing using a USDM Ecu chipping kit.

*These instructions only apply to OBD1 USDM Civic / Integra ECUs.*

Lets get started:

Unscrew the top cover of your ECU:

Next, turn your ECU upside down and unscrew the bottom cover:

 Honda has provided an outlined area showing where all of the new socketing components need to be soldered. Shown below:     

*It is recommended to replace the capacitor at C14(shown below) as these commonly go bad over time.*

Next, turn your ECU upside down and using either a desoldering gun or desoldering braid, desolder all of the component locations shown in the above pictures.

 
Next, install and solder in the following components:

2 .1uf capacitors (shown below) from your ECU chip kit go into joints labeled C51 and C52.

 

The 74HC373 chip (shown below), in the joints labeled '74HC373'.

*BE SURE THE HALF MOON NOTCH IS FACING TOWARDS THE ECU PLUGS.*

The 28 pin socket(shown below) into the area labeled '27C256'.

*AGAIN, BE SURE THE HALF MOON SHAPED NOTCH FACES THE ECU PLUGS.*

Insert your 1.2k resistor (shown below) into the area labeled 'R54' *note the direction of the other resistors*

(only needed on 11F0 and 1720 board types. R54 is not present on "1980" boards and therefore not needed).

Place jumper wire,(excess wire from R54) into position J1

 *This jumper wire can easily be cut to restore your ECU back to completely stock operation if needed.*

Last is the capacitor(shown below) at c14

Your ecu should look similar to this after your finished:

Make sure you install the chip with the half moon facing the ecu plugs.
