3. Step-By-Step Guide To Socketing An ECU

How do you actually socket an ECU? Here’s a comprehensive step-by-step guide to help you through the process.

3.1. Gathering The Necessary Tools And Materials

Before you start, gather all the necessary tools and materials. This includes:

• A clean, spacious workbench
• Anti-static mat and wrist strap
• 10mm Deep Socket
• 6″ & 3″ Extension
• Ratchet
• Phillips and Flathead Screwdrivers
• Sharp Pick tool
• Needle Nose Pliers
• Hot Air Gun / Heat Gun
• 3 – 4 Stripped bread ties or DIP IC removal tool
• DIP 28pin Machined Pin Socket
• 30 Watt soldering iron
• 22ga (super thin) 60/40 Rosin Core solder
• Solder wick

3.2. Preparing The ECU For Modification

Begin by removing the ECU from the vehicle. Follow these steps:

1. Remove the three screw-clips holding the trim panel underneath the glove box and remove the panel.
2. Lift up on the front of the door sill plate. Remove the passenger-side kick panel.
3. Pull back the carpet as far as possible.
4. Remove the four 10mm nuts holding the metal bracket on.
5. Lift up on the metal bracket slightly to slide your hand under it and release the electrical connector on the black box (fan control unit) attached to the bracket. It may be easier to slide the black box off of the bracket. Be careful as there are sharp edges on the bracket.
6. Remove the bracket from the car, pulling the bottom of the bracket out first, otherwise, the top of it will hit the dash. Be careful handling it because the sharp edges will cut or scratch your leather or fingers.
7. Remove the 4 connectors from the right side of the ECU. If you have an auto transmission, there will be an additional 5th blue connector on the left. If the connectors are difficult to remove, first push the connector into the ECU firmly, then depress the button and remove the connector.

3.3. Disassembling The ECU

Disassembling the ECU requires careful attention to detail. Follow these steps:

1. Remove 5 screws from the top cover.

2. (A/T only) Remove 5 screws from the transmission daughterboard.

3. Remove the 5 screws from the side case of the ECU.

4. Remove 5 screws from the bottom cover.

5. Remove 8 screws from the lower ECU board.

6. (A/T only) Tilt the transmission board, remove, and set aside the bracket.

7. Identify the ROM chip that you will be extracting.

3.4. Removing The Original Chip

Removing the original chip requires precision and care. Follow these steps:

1. Strip three bread-ties. Skip this step if you have a DIP IC removal tool.

2. Pass the stripped bread tie wire under each side of the ROM chip. Be careful not to scratch the PCB board with the wire. Twist them together so that you have something to pull up on. You will be re-flowing the solder on this section of the board, so the point of doing this is so that you have a place to pull up on the chip without disturbing other sections of the board.

3. The wires should be set up like this:

4. Heat the ROM chip for approximately 1 minute on high heat. Make sure that you keep the heat gun a few inches from the chip. It is critical to keep the heat gun moving and heat both sides of the chip. Keep upward pressure on the wires with a pair of needle-nose pliers the whole time. This will indicate exactly when the solder has flowed (the chip will release from the board); therefore, you will not be able to overheat the board.

5. The pads should look like this after the chip is removed:

3.5. Installing The Socket

Installing the socket requires careful soldering. Here are the steps:

• OPTION 1: Have a socket ready (with straight pins) and immediately press the socket in after the chip is removed. If it doesn’t go in, do not force it! Go to OPTION 2. By forcing and bending the board with it heated, you risk failed or cold solder joints on the surface mount MCU (the two square chips).
• OPTION 2: Allow the board to cool for 5 minutes. Use desoldering wick or vacuum soldering gun to clear the pads of solder. Insert the socket and solder it in place.
• Turn the board over after cooling for 5 minutes and apply a small amount of solder to the socket and any other components in the area that appear to have been re-flowed (usually grey, not shiny).
• Install the ZIF socket (optional) and re-assemble the bottom board inside of the ECU case, install the bottom cover, and the 5 screws on the side of the case.

3.6. Reassembling The ECU

Reassemble the ECU carefully, ensuring all screws are tightened and connections are secure.
