Introduction

The Ezy-FLASH Pro allows you to store a library of modified tunes, enabling quick and easy ‘flashing’ of your car’s engine control unit to increase performance, drivability and support aftermarket modifications. The plug-in unit can read and clear trouble codes, record high speed logs, display live data and performance metrics. The factory tune is also stored within the unit so that the car can be returned to stock at any time.

Important Safety Information

Safety Warning

The Ezy-FLASH Pro must NEVER be used by the driver while the vehicle is in motion! Doing so is illegal, and is a danger to you, your vehicle, and others.

Safety Warning

NEVER drive your vehicle with any cables connected (including Ezy-FLASH Pro cables) that may interfere with vehicle controls.

Warning - Vehicle Warranty

Reflashing your vehicle with the Ezy-FLASH Pro unit may void all or part of your manufacturer’s warranty. Other than product quality guarantee, there are no guarantees with the Ezy-FLASH Pro, either express or implied by ChipTorque or any Ezy-FLASH Pro dealers. The user accepts all risks and responsibilities when using the Ezy-FLASH Pro.

Warning - Battery

Warning - Reflashing

DO NOT disturb the vehicle, cables, or ECU during the reflashing process, including changing maps, locking, and unlocking the Ezy-FLASH Pro. Interrupting the reflash process may cause a reflash error, which may damage your ECU and prevent your vehicle from starting.

Warning - Repairs

DO NOT attempt any repairs on the Ezy-FLASH Pro unit. No user-serviceable parts inside. In the unlikely event of an Ezy-FLASH Pro device failure, contact the place of purchase and return the unit to them for repairs.

Tuning Maps

You get a whole set of tuning maps included when you purchase the Ezy-FLASH Pro product. Exactly which ones you get depend on the vehicle type, and it’s modifications. Usually you will get at least the following maps bundled with your Ezy-FLASH Pro:

Factory (unmodified tune)
Anti-theft program (car will not start)
Valet (low rev limit, low speed limit)
95 Octane (medium performance, tuned for lower octane)
98 Octane Low Boost (low boost, premium fuel)
98 Octane High Boost (performance tune, premium fuel)

Additional Tune Sets can be purchased from ChipTorque directly.

Check For Updates

The Ezy-FLASH Pro unit is programmed with the latest firmware available at the time of manufacture. It is possible that a newer version is available, and it is recommended that you always use the latest available version.

NOTE: Some updates require the Ezy-FLASH Pro to be unlocked before updating. If so, Tune Manager will inform you. If your Ezy-FLASH Pro is locked to your vehicle, you will need to follow the unlocking procedure.

It is also possible that some refinements are made to the menu structure from version to version. This may mean that the examples shown in this User Manual do not correlate exactly to your Ezy-FLASH Pro unit.

Important Battery Warning

Ensure your vehicle battery is fully charged and its condition is good before beginning any reflashing process, including changing maps, locking, and unlocking the Ezy-FLASH Pro. To minimise the power drain from the battery during reflashing operations, we recommend you turn off all accessories, including lights, entertainment systems / radios, fans / air conditioner, etc. As an extra precaution, an external battery charger may be added to the vehicle, although this is normally unnecessary with a healthy, charged battery.

Connect The Ezy-FLASH Pro

Connect the OBDII cable to the Ezy-FLASH Pro and secure the jackscrews.
With the key in the OFF position, connect the OBDII cable to the Vehicle.
The Ezy-FLASH Pro will start up immediately and display version and other information.
“Ezy-FLASH Pro VIN Locked” will be displayed if the Ezy-FLASH Pro is locked to a vehicle.

Select A Tuning Program

Note: Tuning Programs are sometimes called Tunes, ROMs, or Maps. These terms may be used interchangeably in this document. The exact text shown on the LCD windows in this document may differ from those on your Ezy-FLASH Pro screen.

From Main menu, select “Change Map”. The second line describes the name of the currently installed tuning map.
Navigate the menus to select a Tune Set that best matches your vehicle type.
Select a Tune from the Tune Set that best suits your vehicle.
Press SELECT to view Tune information. Use Up/Down to scroll through pages. Press SELECT when done.

Note: The first time you connect your Ezy-FLASH Pro to your vehicle, the Ezy-FLASH Pro must establish a partnership with your vehicle (“Locking”). During this phase, the Ezy-FLASH Pro will query the vehicle type and check that it is compatible with the Tune you have selected. It will then read and verify the maps in the ECU (“Initial Tune”), so your vehicle can be unlocked and fully returned to it’s original program if desired.

Warning - Reflashing

DO NOT DISTURB the Ezy-FLASH Pro, cables, or vehicle during the reflashing or locking process. Doing so may render your vehicle inoperable. This event is not warranted.

Trouble Codes

Note: Trouble Codes are also known as “Diagnostic Trouble Codes”, or “DTCs” for short. Most modern vehicles, including Subaru, store two sets of DTCs – Current and Historic. Current codes indicate problems that the vehicle still experiencing. Historic codes indicate a problem that has happened in the past, but is not exhibiting itself presently.

Connect the Ezy-FLASH Pro to your vehicle
From Main menu, select “Read/Clear Codes”
From the Codes Menu, select either
1. Read Codes
  1. Select Current or Historic Codes
  2. Inspect all codes
    Press SELECT to read information on each code
2. Clear Codes
  1. Select “Clear Trouble Codes”
  2. Turn key off to reset ECU

ECU Reset

Subaru vehicles clear historic and current DTCs by resetting the ECU. This has an unfortunate side effect; it also clears all other learned data in the ECU. One of these parameters – the Ignition Advance Multiplier - controls additional timing advance, and when it is reset, your vehicle may temporarily lose significant power (up to around 20wkW). All of this data will be re-learned over time and your vehicle performance will improve accordingly.

Live Data View

You can view up to 4 parameters at a time live (in real-time) using this feature. Data logging can be used on any compatible vehicle, not only the ‘locked’ vehicle.

Safety Warning

DO NOT view live data while driving on road.

Connect the Ezy-FLASH Pro to your vehicle
Start Vehicle
From Main menu, select “Data Logging”
From the Data Logging Menu, select “Live Data View”
Ezy-FLASH Pro is now displaying live data parameters
Press ‘SELECT’ to stop viewing Live Data .

Note: Data parameters may differ from those shown. Most versions may support multiple screens of live data. Scroll through screens using UP and DOWN buttons. Some parameters may not be available on all vehicle types. In this case alternate parameters may be used, or the allocated space will remain blank.

Licensing

Note: This section is only relevant for people who wish to use their Ezy-FLASH Pro with multiple vehicles with different ECU styles. An example of when this may occur is if the Ezy-FLASH Pro is sold to a user with a different vehicle type or year model.

The Ezy-FLASH Pro is supplied with the ability to function fully with any supported Subaru vehicle.
There are 3 Subaru ECU styles supported by Ezy-FLASH Pro. Ezy-FLASH Pro comes pre-installed with a single license which may be applied to either ECU style. This license applies to the first vehicle type the Ezy-FLASH Pro t is locked to. Ezy-FLASH Pro can be used on any other vehicles that have the same ECU style.

Before the Ezy-FLASH Pro can be used on vehicles with a different ECU style, a new license must be installed. Contact your Ezy-FLASH Pro supplier for information on purchasing additional licenses if required.
The 3 supported Subaru ECU Styles belong in the following vehicles groups:

WRX/STi MY01-05 (Throttle Cable control)
WRX/STi/FXT/LGT MY04-07 (Drive By Wire, serial reflashing)
WRX/STi/FXT/LGT MY08-10 (Drive By Wire, CAN reflashing)

The year model overlaps are a guide only, since this varies between sales regions.

Environmental Information

Operating and Storage Temperatures

The Ezy-FLASH Pro is designed to operate at between 0°C and 40°C (32°F-104°F) at less than 90% relative humidity, although the display contrast may suffer at the extremes of this temperature range.
Using the Ezy-FLASH Pro outside of this temperature range may cause damage to the unit, and/or may cause it to not operate correctly. Never leave or store the Ezy-FLASH Pro in direct sunlight! Recommended storage temperature is –20°C-50°C (0°F-122°F).

Humidity and Moisture

Do not use the Ezy-FLASH Pro if the relative humidity is above 90%. DO NOT allow the Ezy-FLASH Pro to get wet!!!
The Ezy-FLASH Pro unit is not air-tight. In very cold or humid environments there is a likelihood that condensation will form inside the unit; you would see this as dew on the display window.
It is not advisable to reflash your vehicle when condensation exists inside the unit as this may affect the electronics.
