How to Install a computer chip

How To Do It
First disconnect the battery, you will be messing with the computer and you dont need to get shocked! After the battery is taken care of, remove the glovebox from the passenger side of the vehicle. There is no need to completely remove the glovebod from the car as it will be hanging from the glovebox light cord. I just unbolted the glovebod and moved it to the side.
With the glovebox out of the way, you will see the computer. The computer is mounted with three 10mm nuts. Remove the three nuts and slide the computer towards the firewall and then down, out of its holder.
Now it's time to install the chip! You need to remove the access cover that is on the computer. Remove the two 1/4" bolts that hold the access cover onto the computer.
Directly under the access cover, you can see the Memcal. Remove the Memcal by pushing down on the two tabs on either side of the Memcal.
Plug the chip and the Memcal into the bay in the computer. When in place, the aftermarket chip should be inbetween the Memcal and the computer.
Put the access cover back on the computer, then re-install the computer in the car and replace the glovebox. Reconnect the battery, and perform the idle relearn procedure, if necessary.
Note:If the chip does not require a 160 degree thermostat, you are finished... have fun with the new chip! If your chip does require a new thermostat you are about half way done!
Open the hood and locate the thermostat cover. It is on the driver's side of the engine, near the throttle body.
If you need to change your coolant, now is a good time to do so. If you are lazy like me, you dont need to drain the cooling system. You won't lose much coolant, if the engine is cool.
Once you have decided whether or not to drain the cooling system, remove the 2 bolts that hold on the thermostat housing.
Quickly replace the 160 degree thermostat with the stock unit. Make sure to put the thermostat in the right way! Take note when you take the old one out. This is the same position that the new thermostat must be in!
Put the thermostat housing back together and run the engine to make sure that you have no leaks.
If your car idles fine, and you aren't spewing green coolant everywhere, take your car for a spin! You are done! If the car is having idling problem, try the idle relearn procedure. If that doesn't solve the problem, contact the chip manufacturer.
