10mm socket/wrench
Phillips screwdriver
Prying tool (i.e. flat head screwdriver)
Torx T-15/10
Chip remover
Attempting to install a chip can be one of the
most dangerous things to do to your car.
Frying your computer basically kills your car.
BE VERY CAREFUL when installing an aftermarket
chip. Be sure to ground yourself when you are
in contact with the ECU, motherboard, and
chip. I put this on the web for information
purposes only, and can not be held responsible
for mishaps resulting from your installation.

Open the hood, and look close to the
windshield on the passenger side. There is a
black plastic cover that is over the rain
gutter. There are 4 Phillips plastic screws
that hold the cover in place (see above
picture). To remove these, you will need some
type of prying device (flat head screwdriver)
to get under them while unscrewing. They will
eventually pop off. |

STEP
2. |
Here is a close-up of the plastic screw. |
After removing the plastic screws, you will
need to slide the clip in the center of the
cover over (see above picture). Remove the
weather strip that is on the bottom of the
cover. You can then remove the plastic cover. |
| REMOVED
COVER |
STEP
3. |
Here is the removed cover. |
After removing the cover, you will see the ECU
(computer) in the center of the rain gutter
(see above picture). There is a nut and a
bolt, both 10mm, holding the ECU secure (also
a tab in the back, do not forget about this
when re-installing the ECU). Remove the
computer from the rain gutter (there are also
2 clips keeping the harness from flopping
around in the gutter, unclip these). |
| ECU
NUMBER |
STEP
4. |
Here is the ECU information that the chip
manufacturer will need when ordering a new
chip. ATTENTION!!! There is a specific number
for your ECU, do not use this one when
ordering! |
There is a latch on the side of the computer
where the wiring harness is connected to (see
above picture). To remove the harness, you
will need to slide the latch away from the
wiring harness. |

OPEN |
STEP
5. |
This is what the latch looks like when open |
There are 8 total screws that you will need to
remove to open up the ECU. There are 4
Phillips holding the bracket on, and 4 T-15/10
Torx holding the motherboard inside the
computer. The above picture shows all 4 Torx
screws, and 2 of the Phillips screws. |
| EXPOSED
MOTHERBOARD |
STEP
6. |
Here is the motherboard (very delicate, be
careful when handling). The chip that you will
need to replace is in the lower right hand
corner (mine has already been replaced with a
Garrett version .10 chip). |
Here is a close-up of the chip (note notch in
top left hand corner). When removing the chip,
be sure to note the location of the notch and
be sure to place the notch in the same
location when installing the new chip. I
highly recommend getting a PLCC socket chip
remover to remove the chip (avail. at Radio
Shack). After installing new chip, reassemble
computer in reverse order, re-install the ECU,
and reassemble the rain gutter cover. |
