Window Mount Scanner
to Use and Install
OBD2 Scanner can read up to 75 gauges from
your OBD2 port including:
(O2) Sensor Voltage for all O2 sensors (including
Wide Band sensors)
and/or (MAF) sensor
(IAT) Intake Air Temp sensor
Instantaneous gas mileage.... All
at the same time!
the above 4 gauges can help you tune your car for
plug the scanner into your OBD2 port
it on the window and you're ready to go!
scanner can show up to 18 gauges on 3 windows.
gauges can be shown on each window.
There are 3 buttons on the back to change windows.
No Returns on this item
Scaner is tested before shipping
How to set up the gauge *
menu button is the left button on the back.
other two are Up and Down.
not start the car.
Plug in the gauge to the OBD2 port and turn
the key to run
The gauge will ask you how large your gas tank
is and your motor size.
Use the Up and Down button to choose and Menu
button to select OK.
gauge will scan all gauges and load the default gauge
gauges and clear all gauges.
the gauges you want and name them ABCD...etc.
1 gauge at a time can be called A or B or C.
can pic up to 18 gauges, 6 on each page.
Instantaneous fuel mileage
Bank 1 O2 # 1 ....(front left O2 sensor)
MAP or MAF
Bank 2 O2 #1 .....(Front right O2 sensor)
Intake manifold temp (IAT)
rotate through the gauges that you see..
Press and hold the Down button for 2 seconds.
windows are labeled like this
The manufacturer has a 45 page
PDF to show you how to use this gauge.
of this you do not need.
manufacturer also has a rebate of $9.00.
was the hardest rebate I have ever filled out.
Don't waste you time.... A roadside DWI test is easier.
scanner has trip mileage, alarms, all kinds of stuff,
but for a quick setup
all you need to know is how large your gas tank is,
motor size, and how to get into the menu and change
use a EFIE and/or a MAP
make adjustments to their vehicle. This is the most
to tune your vehicle, but you will have to cut wires.
Adds voltage to the O2 sensor.
prevents the (ECU) from thinking it's too lean and
can make small changes to the air fuel mixture.
connected to the (MAP sensor) Is Used
to make large changes to the
air fuel mixture
Enhancer: When used on the (IAT) is used
to adjust the timing.
This is not needed most of the time.
the ECU using a hand held programmer
like the Bully Dog, Predator, Edge or the SCT programmer.
Bully Dog is one of the best Programmers
will allows you to make some
changes while you are driving,
Most other Programmers do not.
recommend for everyone to re-flash (Reprogram)
the ECU if you can.
give most a 1-3 MPG gain even without a booster.
This will also improve shift points and the timing
See Computer controls for more info
Reprogramming is very easy to do but most Programmers
only give you 1-
3 preset tunes from the manufacturer.
will need to try all three to see which one works
advanced ECU programming tools will let you change
the fuel curve yourself.
is very hard to do and only advanced users should
try this method.
is a PIC of the scanner connected to my F-150
like 1 of the O2 sensors is low on voltage.... but
sensor varies between .14V
and .72V.. This is normal.
computer takes the average and decides if the truck
is too lean or too rich.
peak value is what you want to know.
looked at my rear O2 sensors and they showed .68V
suggests that everything is working fine.
want the rear O2 sensor to have a slightly lower
peak voltage than the peak voltage on the front
I turned on my Very Large HHO booster,
peak numbers dropped to less than .5V
tells the computer that I am lean...
do not want this.
an EFIE to the front O2 sensors will fix this
that the computer will not think it's too lean
vehicles will learn to ignore the O2 sensor
and make adjustments automatically
just disconnect the O2 sensor altogether.
does work on some cars, but you will get
a check engine light.
you have a small Hydrogen Booster on your vehicle
most people will not need to make any adjustments
