Lay Out Parts

PIC_0001.JPG

OK so you have got the nice shinny new box with the avc-r in it.

Once u have finished admiring it from various angles you should open it up.

The best thing to do when starting this is to lay out all the parts and have the wiring diagrams and install

stuff ready to go.

Lay out all the parts and check the documentation that came with the AVC-Rfor the one that has pictures

of the parts.

Check that they are all there.

STEP 1

Disconnect Battery

 

Pretty self explanatory that one. Must do this before starting anything

 

STEP 2

Laying Out Wires

 

OK so start to lay out the wires in you engine bay and see where everything goes.

 

You are going to have to punch the wire that connects to the control module and also the one that wires up

to the ECU through the fire wall.

 

I chose the hole where the factory wires go through to the ECU. Pull back the large rubber grommet and

feed the wires through, you may have a bit of trouble getting it through the first time but keep trying and

you will get it. If you find that the wire has not gone through but you have pushed the wires in then more

then likely the wires have gone into the fire wall between the metal and the insulation, if this happens pull

it back out and try again as other wise you will have to cut the rubber in your passenger foot well to get

the wires through.

STEP 3

ECU Wiring

 

OK now this is where we get down and dirty.

Start by pulling off the black kick panel to the left of the passenger side footwell to expose the ECU.

Now u will notice that there is a cover on the plug, remove this with a small flat head screwdriver then you

will notice that the ECU is held on by a bolt (10 mm) remove this so as you can free the plug. Once you

have removed the plug from the ECU. you can start to examine all the wires.

 

Now this is where u go and grab the wiring diagram for the ECU (remember I told u to have this handy).

 

Once you have the diagram work from the right hand side (the side that was all the wires are facing) and

bear back the wires that u need to do.

AVC-R WIRING COLORS

AVCRWIRE4.jpg

Using the vehicle and also the avc-r wiring diagram start with the Red wire for the ignition power and work

you way along.

 

You want to strip back the wires about 2-3inchs back from the connector as this will give you enough room

to patch up if you make a mistake, and also room to make a good solder joint.

 

Once you have done each joint cover it with a piece of electrical tape.

 

AVC-R WIRE COLOR ECU. WIRE COLOR

GREEN & BLACK WIRE TO BLACK With WHITE STRIPE - GROUND

RED WIRE TO BLACK With THICK WHITE STRIPE - IG POWER

WHITE WIRE TO WHITE - SPEED SIGNAL

GRAY WIRE TO YELLOW WITH GREEN or BLUE STRIP - THROTTLE SIGNAL

PURPLE WIRE TO BLUE WIRE - RPM SIGNIAL

STEP 4

Installing Boost Solenoid

 

Now that you have placed the wires all out and wired up the ECU. you are going to have to mount your

Boost Solenoid. I choose the spot in front of the passenger side strut tower. There is two plugs here and a

nice little flat spot which is an ideal location away from heat etc. If you have something in this spot

(Models with Passenger Air Bag or ABS) then remove the factory solenoid and make up a bracket for it to

go in there.

 

The most critical point about mounting the solenoid is that you use the backing rubber that comes in the

kit. Apparently the solenoid is very sensitive to vibration and can be easily damaged.

 

So if we say that you are going to mount it in the spot with the two plugs, remove the plugs and place the

rubber backing plate on the flat section. Use this to put four self tapping screw into the metal then remove

these and place the Solenoid with the backing plate in the spot and screw the screws down tight (Not too

tight just enough to make a firm mounting)

.PIC_0020.JPG.PIC_0029.JPG.

 

STEP 5

Hooking Up Boost Solenoid

 

On the solenoid you have two pipes, one that has written above it NO and the other that says COM.

 

The one that says NO connects up to your intercooler piping, on the blitz LM spec cooler that I have there

is a brass elbow that you can run the piping to but you can use the factory piping for this.

 

The one that says COM connects up to the wastegate. Use the factory hose or if it is not long enough then

you can use some of the piping that was supplied with the kit.

.PIC_0019.JPG.PIC_0027.JPG.PIC_0028.JPG.

STEP 6

Installing Pressure Sensor

 

Next thing is the pressure sensor. This must be mounted with the top of the sensor upwords, this is very

important as aparently it will not work correctly if it is not placed in this manner. I chose the firewall near

the VIN plate, this location is away from direct heat and any other opstructions.

 

Mark the two hole and then pre drill the two hole then screw in the self tappers.

STEP 7

Hooking Up Pressure Sensor

 

Use the smaller diameter hose that came with the kit and hook it up to the Presure Regulator. This is the

small thing in the last shot, you will need to install a T piece in this pipe and the T piece comes with the kit.

Now where i located the Presure Sensor on the fire wall the pipe that comes with the Apex kit will not be

long enough but you can use some of the larger hose as a temp mesure (mine is still on there after 1

month) and then purchase a longer piece of pipe for this.

 

Run the piping loosely inbetween the manifold and the engine block and around to the pressure sensor.

STEP 8

Finishing Off

 

Ok so everything is in and all wired up, double check everything and then re connect the negative terminal

back up.

 

Check everything again then crank the car over, you should see the AVC-R start up with the cool looking

APEX logo and then it goes into the menu.

 

OK stop admiring it and turn off the engine.

 

Now you can properlly tie off all the wires in the engine bay and then fix up the wires in the loom etc and

place all the panels back on.

 

note - i have not included the install of the actual Comand unit, i think you can work out where you would

like to place it for yourself but a word of warning. KEEP IT AWAY FROM PRYING EYES. Or else you won't be

the only one admiring you new handy work.
