Quick Start

Congratulations on your purchase of the AccessPORT. Please read this section to

get started using your AccessPORT quickly.

The AccessPORT is a handheld device used to reprogram your vehicle’s Engine

computer (ECU) through the diagnostic (OBD-II) port. The AccessPORT handheld

programmer comes pre-loaded with performance and convenience mapping.

In addition, the included Map Manager software for your PC allows you to

organize and transfer maps to the AccessPORT.

AccessPORT Features

With the AccessPORT handheld programmer, you can:

•Program (Flash) your ECU with improved Maps

•Instantly switch between up to 10 different Realtime Maps for

different modes of operation.

•Store up to 6 Base Maps

•Check to see which Base Map is currently in use

•Display Trouble Codes (CELs)

•Clear Trouble Codes (CELs)

•Reset ECU’s learned memory

•Return the vehicle to 100% stock programming

•Display Turbo boost values (in psi)

What is a Map?

A map is a special program designed specifically for your factory Engine

computer (ECU). By transferring different maps to your ECU, you can take

advantage of particular modifications or even enhance the performance of a

stock vehicle. Additional maps can also be used to allow the engine to operate

in Valet mode, Anti-Theft Mode, and modes for specific fuel quality, etc.

Your AccessPORT is capable of storing up to ten (10) Realtime Maps and up to

six (6) Base Maps. With the Map Management software, you can store and

organize the maps on your home PC and load them on your AccessPORT for use

on your vehicle.

Maps – Base vs. RealtimeMaps – Base vs. Realtime

Maps – Base vs. Realtime

Your AccessPORT utilizes proprietary technology to provide the ability of instantly

switching between ECU maps. This map switching can be performed without

actually writing new information into the ECU’s embedded flash memory. The

advantage of this technology is the convenience of switching ECU programming

quickly and easily, without reducing the finite life-span of the ECU’s flash memory.

There are two map types that are utilized by the AccessPORT, Base and Realtime.

Realtime MapsRealtime Maps

Realtime Maps

Realtime maps are loaded instantly and are used by your ECU without being

programmed into your ECU’s flash memory. This enables the AccessPORT user

the ability to alter the way in which the ECU functions without diminishing the

ECU’s Flash Memory life-span.

Realtime maps have the ability to instantly change fuel curves, ignition timing,

boost mapping, rev limits, etc. This means you can easily and quickly switch

between various performance and convenience maps as your needs change.

Realtime maps are selected through the [SWITCH MAP] selection on your

AccessPORT’s Main Menu.

In the event that your ECU is reset by disconnecting the battery or performing

what is known as a “hard reset”, the Realtime map loaded will no longer be in

use. The ECU will revert back to the Base Map.

Base MapsBase Maps

Base Maps

Base maps store the core features that will remain constant regardless of what

different modes of operations you select. These maps have the ability to change

ALL the data in the ECU.

Base maps are selected through the [CHANGE BASE MAP] selection on your

AccessPORT’s Main Menu.

Base maps are programmed into the ECU’s Flash Memory and will constitute the

use of a flash when selecting. When your ECU is reset by disconnecting the

battery, it will automatically revert back to the last base map used.

You should only need to change your base map when you need to alter a core

feature within your ECU or Check Engine Light activity.

Base Maps contain both Real Time and Base Map information.

Initializing your AccessPORTInitializing your AccessPORT

Initializing your AccessPORT

To begin using your AccessPORT, you must first perform the following steps that

will enable your factory ECU with the proprietary AccessECU technology. You

cannot access the Main Menu or other features of the AccessPORT until it has

been installed on your ECU using the following steps.

The AccessPORT comes pre-loaded with Maps. In the event you wish to change

the Maps prior to installing your AccessPORT, please refer to page 47 before

performing these steps.

Step 1:Step 1:

Step 1:

Put your key in the ignition and leave it in the ‘OFF’ position. Connect the two

green Test Mode connectors located under the driver’s side dash, left of the Steering

Column. To connect the Test Mode connectors, you simply need to plug them

into each other. Please refer to the diagram below:

WARNINGARNING

ARNINGARNING

ARNING:

Before beginning, please verify your vehicle is in proper working order

and is properly maintained. It is also imperative that the battery be

fully charged and in good condition. If the battery voltage drops

below an acceptable amount during the reprogramming process,

the ECU will be damaged and cannot be recovered. Your vehicle will

not run if this occurs. Avoid all electrical noise that may interfere

with the sensitive communication between the AccessPORT and the

ECU. Any interference may result in a programming failure and

damage to your ECU.

Step 2:Step 2:

Step 2:

Use the supplied Initialization Connector (BLUE for 2002 vehicles, WHITE for 2003-

2005 vehicles). Attach the Initialization Connector to the complementary whitish

(semi-clear) factory connector located in close proximity to the green Test Mode

connectors. It may be difficult to find but this connection is required, please use

patience.

Step 3:Step 3:

Step 3:

Turn the ignition key to the ‘ON’ position but DO NOT start the engine. Verify the

Check Engine light on your dash is blinking. You may also hear the radiator fans

cycling on/off as well as the fuel pump cycling, etc. THIS IS A NORMAL FUNCTION

OF TEST MODE. If your vehicle is not displaying a flashing Check Engine Light,

please refer to page 47 for additional steps before continuing.

Step 4:Step 4:

Step 4:

Connect the DiagPORT cable (D-sub 9-pin) to the complementary connector on

the AccessPORT.

Step 5:Step 5:

Step 5:

Connect the red end of the supplied DiagPORT cable to the diagnosis port con-

nector located in the lower portion of the dash (below the steering wheel). The

AccessECU logo will be facing you (up). Make sure connection is firm and secure.

connections and refer to “Tips and Troubleshooting” on page 46.

Step 6:Step 6:

Step 6:

The AccessPORT will automatically prompt you to select a Map that will be

programmed (flashed) to your ECU. Pressing the large round button (OK) will

display a list of available maps pre-loaded on your AccessPORT.

Using the AccessPORT arrow keys, select the map that you wish to program

into your ECU. This map will be your “base” map that replaces the original

factory map on the ECU and will not be erased when the battery is

disconnected or ECU reset. Once you have chosen your map, press the large

round OK button.

Turn the Ignition key to the ‘OFF’ position. Next, turn the ignition to the ‘ON’

position but do not start the engine. Once the ignition is in the ‘ON’ position, you

will press the large OK button on your AccessPORT to begin the programming

process. You must press the OK button 3-10 seconds AFTER turning the key to

the ‘ON’ position.

Step 8:Step 8:

Step 8:

The AccessPORT will first display an “Initializing” message followed by dots

indicating progress. During this process, you may notice your check engine

light stops flashing and the radiator fans, fuel pump, etc stop cycling. This is

NORMAL.

Once it has completed initialization, the screen will go blank briefly and then

display a FLASHING message. DO NOT DISTURB THE ACCESSPORT DURING THIS

PROCESS. This procedure will take anywhere from 5-10 minutes to complete.

Disconnecting the AccessPORT, or attempting to start the vehicle, will cause the

programming to fail and may render your vehicle inoperable.

If you receive an error during this step, please refer to the Troubleshooting steps

beginning on page 48.

Go drive! Your vehicle is now AccessPORT enabled!

Once the AccessPORT has finished reprogramming, it will display a message

prompting you to turn the ignition key to the ‘OFF’ position.

Turn the ignition key to the ‘OFF’ position. Next, press the OK button on the

AccessPORT. The AccessPORT will now display the MAIN MENU. At this point,

your AccessPORT is married to your ECU and the Map you selected is now active

on your ECU.

You can safely disconnect the AccessPORT from the vehicle.

DO NOT disconnect any cables during this time. Doing so will cause a

programming error and your vehicle will not start. Take care with the

DiagPORT cable connection by avoiding any tension. The DiagPORT

cable remains connected to the vehicle’s diagnosis port through friction,

there is no locking mechanism. Kicking, jarring, or pulling on the

connector may disconnect it and corrupt the programming.
