Porsche 964 Chip Installation Instructions
I. Removal of the control unit
  1. The control unit that houses the chip is located under the driver’s seat.
  2. Move the driver’s seat to its rearmost position.
  3. Using a 10 mm socket, remove the four nuts securing the control unit to the floor.
  4. Lift the control unit up, then forward.
  5. Remove the electrical connector by pulling back the stainless steel retaining clip and rotating the plug back and away from the control unit.
  6. Opening the control unit
II. Opening the control unit
  1. The control unit’s cover is held on by the crimped metal tabs. These tabs must be carefully bent straight to allow the cover to be removed.
  2. Separating the two circuit boards to gain access to the chip requires extreme care.
  3. The next step is to separate the boards at the end away from the electrical connector. You will see that the two boards are connected with a ribbon cable, and to either side of the ribbon cable are posts that hold the boards together. These posts are connected with a ball and socket joint. Place a small screwdriver in one of the slots of the socket side, and gently pry open. Placing pressure only on the plastic strip the ribbon cable connects to, and never to the circuit board itself, push the two boards apart. First separate one side, then the other.
  4. With the back of the boards apart, lift the top board, gently stretching the ribbon cable. With the board tilted up, turn the box so you are looking at the electrical connector. At either side of the top row of pins you will see vertical tabs holding the top board to the box. Using a small screwdriver, push the tabs in towards the center.
  5. Take the screwdriver and push down from above the top row of pins. When the lip above the pins clears the connector housing, you will be able to pull the top board back.
  6. Once away from the front of the box, the top board will unfold like a book. The chip is on this board, not the fixed board.
III. Remove the old chip and install your new FabSpeed performance chip.
  1. Identify the chip to be removed. It will be the only socketed chip on the board. It will also have a silver-gray label with a number stamped on it. The number will be: 1 267 35_ ___.
  2. Chips are “keyed” for direction. Look at the chip and you will see that one end is notched. Note the direction of the notch so you can line up the new chip properly. Installing the chip backwards will damage your control unit. Make absolutely sure you put the chip in correctly! You will also see a matching notch on the socket as well as a painted rectangle on the circuit board itself indicating the correct direction of the chip.
  3. Gently pry the chip up and out of the socket, working first at one end and then the other so as not to bend the pins.
  4. Press the new chip into place. Again, make sure the chip is oriented correctly (with the notch in the right direction). New chips sometimes have their pins spread wider than the socket. If this is the case, first push in one side and very gently press on the chip to bend the pins in a bit. Then remove the chip and do the other side until all the pins line up and the chips may be pushed firmly into place.
  5. Double check the chip orientation before putting the box back together in the reverse order of disassembly.
IV. Old chip storage
  1. Use the container your new chips came in to store the original chip.
If you have any questions, please contact FabSpeed, Inc. tech support.
