Setup Menu Overview
To enter the menu screen below simply press the ENTER (middle) button once
Scramble: Scramble is to add additional boost (via duty) for a set
amount of time. Entering this option allows you to set how much duty
and how much time to add it for.
Display: This option allows you to select if you want your boost settings
and display in bar, psi or kpa
Overboost: This option allows you to set a boost level at which the V4
will display a warning and cut boost in the event of a over boosting
fault, this option also allows you to switch this feature off.
Input Trig: This is where you go to set up what you want to use the
external trigger input wire for, if anything. The 4 options are scramble
(as explained above), memory change which is where it increments to
the next memory setting e.g. 1>2>3... , boost cut where it'll cut to
minimum boost if this wire is switched to earth and lastely off in the
case of you not wanting to use this wire.
Anti Spike: This is to set a percentage which is proportional to the
recovery time to ramp up boost in throtle off on situations like gear
changes. This is often used to compensate for an inadequate wastegate
Hard Reset: This is for cases where you may want to return to all the
factory settings your V4 was supplied with. Some examples of these
cases might be when you are swapping the V4 to another vehicle, when
you have changed things and lost your way or when things are just
acting crazy for no aparent reason.

Scramble Setup
Press ENTER once to access
menu screen Press ENTER
again to access
Scramble setup
Use the UP and DOWN buttons to adjust the
'Secs' setting inline with how many seconds
you'd like the additional boost to stay on for
and then press ENTER to continue
Use the UP and DOWN buttons to adjust the
'Perc' setting inline with how much additional
duty you'd like to add whilst on scramble and
then press ENTER to save and exit
In running mode the scramble can be
triggered by pressing the up button or
the remote trigger when the 'input
trigger' is setup as scramble. When the
scramble is triggered the 'SCR' and the
remaining seconds are displayed in the
top right hand corner of the screen as
displayed to in the image to the left
MULTI-SCRAMBLE
The V4 has Gizzmo's multi-scramble feature. With this you can re-press the UP
button or remote button whilst on scramble and the V4 will add another
additional scramble duty and replenish the seconds. That's very confusing so
here's an example. If you had your scramble duty set to 3% and secs set to 5.
Upon triggering scramble 3% duty would be added to your base duty for 5
seconds. If after 3 seconds you decided you needed more boost again, you can
repress the trigger and you would then have your base duty + 6% (3% + 3%)
and the seconds would reprenish to 5sec again. This can be done up to 2 times
in addition to the first scramble.

Over Boost Setup
Press ENTER once to access
the menu screen
Press DOWN twice and
ENTER once to access
the overboost setup
NOTE: When you first enter the overboost setup it may display 'OFF'. If you
go once press above the maximum boost (in this example 3.2bar) or one
press below zero the display will read 'OFF' to indicate that overboost will be
disabled.
Use UP and DOWN to set the limit that
you would like to set at which the V4
warns you of an overboost situation and
actively switches to minimum boost. Once
you have set this press ENTER to save
and exit to the running screen
When you exceed the overboost level the display will show the
WARN logo like above and the duty will drop to zero as above

Input trigger Setup
Press ENTER once to access
the menu screen
Press DOWN 3 times and
ENTER once to access the
input trigger selection
Use UP and DOWN to highlight the selection
you would like (descriptions below) and then
press ENTER and your selection will be saved
and you'll return to the running screen
SCRAMBLE: this allows the remote input to trigger scramble and multi
scramble events. As with all remote triggering options the remote wire must
switch to earth so the remote wire goes to one side of the button/switch
and the other must be connected to earth
MEMORY: this makes the remote trigger wire increment the memory
selection e.g. 1 > 2 >3... Again it switches to earth so the remote wire goes
to one side of the button/switch and the other must be connected to earth
BOOST CUT: this is used to switch to minimum boost, so mainly as a
safety feature. An example of this may be if you wired a level sensor from a
water/meth injection tank so that if it got low it would switch a eath to the
remote wire to cut boost. Please be aware that when the aux boost cut is
active (cutting boost) the running display will indicate this as below.
OFF: this is obviously to switch the aux input off so that if it earths out
nothing happens.
EXIT: this is to return to the running screen with no changes

Anti Spike Setup
Press ENTER once to access
the menu screen
Press DOWN 4 times and
ENTER once to continue
to the anti spike selection
Use the UP and DOWN buttons to adjust
the anti spike to the desired setting and
then press ENTER to save and exit.
What is Anti Spike?
As wit h everything, wast egates t ake tim e to open, especially internal
wastegates, and in a situation where t hey are required t o react
quickly ( flat shifting gears at high revs, off/ on t hrot t le quickly whilst
on boost at high rpm ) this som et im es result s in a boost spike. Anti
Spike largely elim inat es t his and can be adj usted from 0 t o 100 wit h
100 being suitable for vehicles with a large am ount of boost spiking
and 0 suiting cars with no spiking issues. I deally you want to keep
this set t ing as low as possible because t he higher this is, t he longer it
will t ake t o ret urn to your desired boost set ting.

Hard Reset
Press ENTER once to access
the menu screen
Press DOWN 5 times and
ENTER once to access
the hard reset option
By default No will be selected. Should you
wish to continue a reset press UP once and
ENTER. Otherwise press ENTER to exit.
Another warning just to let you know all your
setting will be erased perminently. Should you
wish to continue, press UP once and ENTER.
The V4 will restart with all the factory default
settings as per when it was purchased
CAUTION!
If you do a hard reset, all user settings e.g.
scramble, input trigger, all memory duties,
gains pressures etc will be erased. You will end
up with all the factory setting as per when the
unit was supplied and as such, will have to
program everything again, you've been warned.

Adjusting the Memory Setting
What is start ???
This refers to when the V4 will start
taking control over the wastegate e.g.
as opposed to letting it operate
manually without intervention from the
solenoid. When the boost reaches the
'start' pressure, the V4 will start
operating the boost solenoid.
Hold DOWN
button until
screen changes
The setting screen will start by
flashing the 'start' setting. UP
and DOWN will increase/
decrease this setting. When you
have set this to the desired
setting, press ENTER to continue
to the Duty setting.
The 'duty' text will now be
flashing. UP increases the
duty, and therefore boost, and
DOWN decreases the duty. It
is impossible to know how the
duty will impact the boost, so
please read below. When you
are satisfied with the duty,
press ENTER to continue to the
gain setting.
VERY IMPORTANT TIP :)
Whenever you adjust the duty in the
setting mode you can then drive the
car (recommended in 3rd or 4th gear
at sufficent revs) and the V4 will
display the boost pressure on the
setting screen tempoarily, this makes
it very fast to set up.
The 'gain' setting will now be flashing.
UP increases the gain and DOWN
decreases it. We'd recommend skiping
this setting if you are setting a new
boost level and coming back to it after
the boost is set (see the quick start
guide). Press ENTER to continue
At this point the V4 needs to learn the
'stable' boost for the set duty. Drive the
car under full throttle at sufficent revs
and load to attempt to get the 'Max'
reading on the screen as high as
possible. You may see higher boost on
the real time readout than is recorded
on the 'Max' reading, this is simply
because the boost you have seen is not
stable. Once you have finished, press
any button to lock this setting in
memory.

Glossary I
D ispla y Se t t in gs
The V4 can display real tim e boost in Pounds, Bar or Kpa. All t his can
be set in the display m enu. Exam ple: 1bar equals 14.5lb which equals
100kpa.
D ut y
This dut y cycle, also referred to as the ‘Base duty’ can be adj usted
from 10% to 90% to adjust t he boost level. Every vehicle has a differ-
ent response to dut y cycle and essentially t he only way t o work out
your dut y cycle vs boost relat ionship is via t rial and error starting
from a low dut y cycle. A lower dut y cycle equals lower boost and
typically your boost won’t st art t o rise t ill at least 20% .
Ga in
Gain effects how quickly t he t urbo com es on boost . I deally t his would
be set as high as possible; however, if this is set t oo high
overshoot ing and boost inst ability can occur so there will be an ideal
set ting for this that will be different from vehicle t o vehicle.
Mem ories
The V4 has 6 m em ories in t ot al and can fast switch bet ween these.
This m eans t hat when you select t he next m em ory the boost will
change im m ediat ely which is an advant age when changing m em ories
whilst racing. Each m em ory has it s own gain set t ing (refer to ‘gain’
in this glossary) and control start pointOver Boost w a rning
Via the m enus, you can set an over boost pressure to flash t he
display and at t em pt to drop t he boost should your vehicle exceed t his
set pressure lim it .

gizzmo
ELECTRONICS
Glossary II
Anti Spike
A unique feature of the V4 is ‘Anti Spike’.
As with everything, wastegates take time to open and in a situation
where they are required to react quickly (flat shifting gears at high
revs, off/on throttle quickly whilst on boost at high rpm) this
sometimes results in a boost spike. Anti Spike largely eliminates this
and can be adjusted from 0 to 100 with 100 being suitable for
vehicles with a large amount of boost spiking and 0 suiting cars with
no spiking issues. Ideally you want to keep this setting as low as
possible because the higher this is, the longer it will take to return to
your desired boost setting.
Solenoid Supervisor
The V4 const ant ly m onit ors the boost cont roller solenoid output
channel t o ensure t hat t here are no m alfunctions and should
anything go wrong t he V4 I MMEDI ATELY displays ‘SOLENOID FAULT’
to warn you of a fault wit h your solenoid, solenoid loom or out put
driver. The V4 will also briefly pulse the solenoid whenever t he key is
turned on in order to ensure it is fully operational. If for any reason
the 'SOLENOID FAULT' displays without having a solenoid/loom fault
it can be switched off via the SOL TEST in the setup menu
