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.
