LETRIPP II SOFTWARE USER GUIDE

(DEALER VERSION)

Perfect Power Online Manuals.

 

Support for your Perfect Power Unit.

ONLINE MODE

The Online mode of communication means that there is a constant communication flow between the unit and the software. It does not matter if either the RS232 or USB type of communication is used, the screens and the functions will remain the same.

 

We define ONLINE as the state between the software and the unit where the data between the software and the unit is always identical.  The software has been designed to maintain this relationship at all times.

 

NOTE: The Online information comes from the connected unit and will differ from unit to unit.  We have used various units as examples to demonstrate various points. Please understand that your screen and possible screen selections will differ from what you see here.

 

 

GENERAL SCREEN

LetRipp II Windows Tuning Software - General Software Screen

LetRipp II Windows Tuning Software - General Software Screen

As it is visible from the above screen examples, it is possible to get almost any combination of screen layout (screen shot on the right hand side).  Most likely the screen you will first see when you start the program, is the empty screen on the left hand side.

 

 

LOADING A MAP FILE

 

You have two options to LOAD a Tune Map – using the Menu bar or the Icon Task bar.

 

Using the Menu Bar, click on “File”, then select “Load File”. The “Open File” screen will open, as shown to the left.

 

The default “Operating Directory” is “C:\Tune_MapFiles”.  This directory has been created on your hard drive for the purpose of storing Map Files.  Should you wish to locate a file in a different directory to the default “Operating Directory”, click the “Browse” button and select a new directory on your computer.  Once a directory has been chosen, it will be stored for future use.

LetRipp II Windows Tuning Software - Loading A Map File

The program will only display Map Files that are suitable for your unit. In this example, these are the compatible Map Files for the product XMS4.

 

To LOAD a Map File, simply select the desired file from the list, and then click on the “Load” button. The program will automatically replace all screen contents with the information from the file and also send down (download) the map data to the unit. The loading of a file can be done while the vehicle is running on the unit. Depending on the size of the data being downloaded, allow approximately 3 seconds for the unit to respond to the new data.

 

On the “Open File” Screen, the DELETE button will delete the selected Map File from the hard drive of the computer.  When the “Delete” function is selected, the software will prompt the User to confirm the task (deletion).

LetRipp II Windows Tuning Software - Load a Map File

LetRipp II Windows Tuning Software - Load a Map File

When downloading a saved file or the default map to the unit, multiple windows are opened as the polling number decreases, all displaying the same problem, “The downloaded data had a problem in the format, Unit return a question mark!” Check that the Regional and Language Options in the control panel have been set to use the decimal (.) and not the comma (,) The unit works with the decimal point (.) in the Tuning and Config maps and will incorrectly apply the data when the comma (,) is used causing the problem.

 

WARNING: Once the file has been deleted, it cannot be recovered by the Windows Operating System and will be gone forever. A deleted Map File cannot be restored in any way, so exercise caution when Deleting Map Files.

 

LetRipp II Windows Tuning Software - Open File Icon Using the Icon Task bar, click on the “Open File” icon as shown to the left.

 

 

SAVING A MAP FILE

 

LetRipp II Windows Tuning Software - Saving a Map File

You have two options to SAVE a Tune Map – using the Menu bar or the Icon Task bar.

 

 

Using the Menu Bar, click on “File” and select “Save”. The SAVE function will allow you to provide a file name and a suitable description for the map being saved. The directory where the maps are saved will be the same directory that has been specified as the “Operating Directory” on the File Open screen above.

 

 

You can also use the FAST SAVE option on the Menu list.  The FAST SAVE function will save your map with a common name (“AFastSave”) and with a common description. The keyboard short cut for the Fast Save is “Ctrl + S”.  Every time the “Fast Save” option is exercised, an incremental number is attached to the file name, thereby making it unique.  An unlimited number of fast save files can be stored on your hard drive as each saved map file is only approximately 92KB in size.

 

 

If the FAST SAVE function is used, the saved Map Files will also be displayed in the list of Map Files. Should the “Description” of the Map File need to be changed, and then simply double click on the selected file name. An editing dialog box such as the one to the left will appear, allowing you to change the description of the selected Map File.

LetRipp II Windows Tuning Software - Saving a Map File

LetRipp II Windows Tuning Software - Save Map Icon Using the Icon Task bar, click on the “Save Map” icon as shown to the left.

 

 

 

NOTE: The map files that are saved can only be loaded by the same unit type. Map  migration between different product units is not allowed and not supported.

 

 

VIEWING THE MAIN MAPS

LetRipp II Windows Tuning Software - Viewing The Main Maps

Click on “Maps” on the Main Menu bar, and check which maps are installed in your unit. Take note of the keyboard short-cut function key assigned to each map name. You will notice that when you use the function keys, the maps will toggle to be visible or not.  Toggling the Maps to be visible or not, will not change the active state of the Map.

 

You can also move the maps on the screen by placing your mouse cursor on the edge of the map and clicking with your left mouse button so that the cursor changes to a cross.  Keep holding down the button to move the map.  If your physical screen is very small, less then (800 x 600), then very little will be able to be viewed at the same time.  The software will prevent you from dragging the map off the screen.

 

Should the Maps need to be relocated automatically, click on the option “Reset Map Positions” at the bottom of the “Main Map” Menu.  This will move all the screens to be one on top of the other in the top left hand corner of the screen.

 

 

ENTERING NUMBERS OR VALUES ON A MAP

 

There are many ways to enter values or data into the tune maps.  Some of the techniques are suitable for desktop editing, while others are more suitable for in-car tuning with a laptop.

 

 

Single Cell Entry

 

Simply click on the map that you wish to edit.  Use the “Arrow” keys on your keyboard, to navigate to the desired place, then type in the value or number that you wish to have entered.  Press “ENTER” on the keyboard, when done. Using the ENTER key on the keyboard, is very important as it confirms the end of your entry and then sends the data down to the unit.

 

LetRipp II Windows Tuning Software - Set Column

Set Column


This will set the entire selected column of a map.  Click or select the column that you wish to have changed, then type in a value or number and press enter.  The entire column will change to your typed-in number. The keyboard shortcut key for “Set Column” is Ctrl + C.  If have selected the icon, then the “Set Column” function will remain active until such time the icon is clicked again, to deactivate it.  The icon will remain indented (like a button) to show you that it is still active.  If you used the keyboard shortcut command, then the function will be disabled after it has been used (in other words, it won’t remain “ON” like when you click on it and it becomes indented).

 

LetRipp II Windows Tuning Software - Set Row

Set Row


This will set the entire selected row of a map. Click or select the row that you wish to have changed and then type a number and press enter. The entire row will change to your typed in number. The short cut key for Set column is Ctrl + R. This function will not work on side maps. If have selected the icon, then the Set row function will remain active till such time the icon is clicked on again to deactivate it. The icon will remain indented to show that it is still active. If you used the keyboard shortcut command, then the function will be disabled after it has been used.

 

LetRipp II Windows Tuning Software - Set Block Icon

Set Block


This will set a block of 3 cells in all directions from a selected cell.  Click or select the center cell and then type a number and press enter.  The selected block will change to your typed-in number. The keyboard shortcut key for “Set Block” is Ctrl + B. This function will not work on side maps.  If you have selected the icon, then the “Set Block” function will remain active until such time the icon is clicked on again to deactivate it. The icon will remain indented to show that it is still active.  If you used the keyboard shortcut command, then the function will be disabled after it has been used.

 

Blending


The “Blending” function is a very powerful feature as it can be used to fill a large amount of numbers or values into a map.  This feature will benefit the Tuner, as you will only need to enter four values in each corner of the Map to get the rest of the values automatically entered by the LetRipp II Software.  The Blend function can also be used in single row or columns where a simple blend is required, such as a side map.

You will first need to enter values into the four corners of the Map. The Main Map is used in this example.

 

 

In this example, we entered “0” in the top left hand corner, “110” in the bottom left hand corner, “245 in the top right hand corner and “180 in the bottom right hand corner.

Once your corner numbers or values have been entered, select the TOP LEFT hand corner with a mouse click or move the editing cursor.

 

LetRipp II Windows Tuning Software - F1 - Fuel Injection Map

Then hold down the “SHIFT” key while moving your editing cursor to the BOTTOM RIGHT corner of the field that you wish to have edited.  The Map will then be coloured in blue, such as the example on the left.  Once you have a selection, press “G” for GO.  “G” is the keyboard command for activating the “Blending” function.

 

LetRipp II Windows Tuning Software - F1 - Fuel Injection Map

As shown in the screen shot to the left, the rest of the values in the Map have been automatically calculated and entered by the LetRipp II Software.  The Blending function will blend all the numbers between the four outer corners.  The only numbers that will not be changed are the original numbers entered in the four outer corners.

 

LetRipp II Windows Tuning Software - F1 - Fuel Injection Map

Block Area Increase or Decrease “C”

The “Block Area” function is a very powerful feature as it can be used to increase or decrease the values in the selected area of the map.  This feature will benefit the Tuner, as you will only need to high light the area of the map that is too rich or too lean and then enter the amount by which each number must increase or decrease.  The Block area function can also be used in single row or columns where a simple increase or decrease is required. You will first need to select area that needs to be changed in the Map. The Injection Map is used in this example.

LetRipp II Windows Tuning Software - F1 - Injection Map #1

Once the area of the map is selected then press “c” on the keyboard. The following window will open.


Enter the number by which you need the values in the Map to increase or decrease. As displayed in the example, the amount that the selected are will increase by will be “100” (to decrease it would be –100) Press “OK”

LetRipp II Windows Tuning Software - Decrease Values on Map

The selected area has now been increased by 100

LetRipp II Windows Tuning Software - Block Area

Live Tuning

You will be able to tune the position of where your engine is (green cursor), while running your Map.  To do this “Live Tuning”, use the “M” for MORE and “L” for LESS at a particular point.  This will add or subtract from the existing number or value in the map.


Change the Edit Field

There is a way to change the EDIT field by adding or subtracting from the existing number in the Edit field (blue cursor).  Use the “Z” key for more and the “X” key for less.

 

 

DATA DISPLAY

LetRipp II Windows Tuning Software - Data Display Settings

Select “Data Display” from the Main Menu Bar.  The Data Display Settings dialog box will appear as shown in the example above.  Each item in the Display list can be displayed in various ways.  Click on an item on the list to select that item.  Once the item has been selected, the information that can be edited will be displayed in the window on the right hand side.

 

The Display Name is the name of the item that you wish to have displayed for that item. Try to keep the name below 16 characters long.  The “Reset all Display Names” button is used to reset all your display names back to the original or default names.

 

The Low Scale and High Scale items are only used for the graph function and can be ignored if the graph function is not being used.

 

Select “SN” for a “Small Number” display, “LN” for a “Large Number” display and “GR” for a “Line Graph” to graph the item.

LetRipp II Windows Tuning Software - Data Display

Once all the selections have been done, the screen will then display all your items.  If an item has been lost on your screen, use the “Refresh Display Items” button.  This button will refresh the screen and sort all items so that you are able to see them again. A maximum number of 24 small and 17 large display windows can be opened.

 

 

CONFIG SCREENS

LetRipp II Windows Tuning Software - Configuration Screens

Select “Config” on the Main Menu Bar.  A list of the available “Config” screens will appear.  The “Config” screens have a global impact on all tuning that is done.  All the “Config” screens are always active in the calculations of the unit. The list of available “Config” screens will differ from product to product.  This particular example is from a Fuel Tuner.  Take note of the keyboard shortcut keys for each “Config” screen.  All the keyboard shortcuts for the “Config” screens start with the “Shift” key followed by a function key.


There are three different types of “Config” screens:


Parameters and System Def

These are for setting various global values that have an impact on the running of the unit, for example, the “Max Fuel Limit”.


Status Display

This will show you what the unit is doing or what functions are presently active, for example, which Map the unit is presently running in.


Calibration

The Calibration Screens will differ from product to product and therefore you may only see two different Calibration options or five as in the example of the Fuel Tuner product.

 

 

CALIBRATION SCREENS UNDER CONFIG

LetRipp II Windows Tuning Software - Calibration Screens Under Configuration

Under the “Config” option on the Main Menu Bar, a number of Calibration options will be available, depending on the type of product that you are connected to.  Each Calibration option will open up a relevant screen.

 

All the Calibration screens are scales for maps.  The RPM Calibration is used on all maps and can only be setup when selected under “Config”.  All Calibration screens will have the same colour, as shown above.  We have included three examples above to show the slight differences between the way they look.  All screens have an “Apply” button that will apply the changes you have just entered.  To calibrate the TPS, display the TPS% value as shown in section 7.4.7. Turn on the Ignition. The percentage displayed is the Lower calibration value, then press the accelerator pedal to full throttle and use the displayed value for the Upper calibration.

 

Once a change has been made, the change will be indicated immediately on all the screens that use this calibration and this change will also be downloaded to the unit.  The new scale will have an immediate effect on the unit.

 

 

STATUS DISPLAY

LetRipp II Windows Tuning Software - Status Display

Select “Status Display” from the “Config” Menu Item.  The amount of items on the display will differ from product to product.  The “Status Display” screen is used to inform the User which function the unit is presently running in.

 

If a function is marked in BOLD, then that function is presently active.  “The Status Display” cannot set or change any of the function states.  It simply just shows the combined result of the “Parameter” and “System Def” in the map, unit wiring and any other function that has an affect on the unit.

 

The “Status Display” function can also be selected by clicking on the icon as shown above.

 

 

PARAMETER DISPLAY

LetRipp II Windows Tuning Software - ShiftF1 - Parameters

 

LetRipp II Windows Tuning Software - Parameter Display Icon

Select “Parameters” from the “Config” Main Menu item.  The “Parameter” screen will be displayed with a variety of features.  The “Parameters” function will be mainly used in the setting up of a vehicle’s installation.  If you want to find out more about the “Parameters”, RIGHT CLICK on any item and HOLD the RIGHT button down.  The relevant information will then be displayed.

The “Parameters” screen can also be selected by clicking on the icon as shown above.

 

 

SYSTEM DEF (SYSTEM DEFINITION)

 

Select “System Def” from the “Config” Main Menu item.  The “SYSTEM DEF”display box will appear as shown above.  The “System Def” contains system settings.  If an item or setting is unfamiliar to you, use the Help feature to see more information about it, by right clicking and holding down the right mouse button.  The amount of options on the “System Def” screen will differ from product to product.

LetRipp II Windows Tuning Software - ShiftF2 - System Definition

LetRipp II Windows Tuning Software - System Definition Icon The “System Def” screen can also be selected by clicking on the icon as shown to the left.

 

 

HELP ON ITEMS

LetRipp II Windows Tuning Software - Help On Items

The LetRipp II Software has an extensive, built-in HELP feature on all functions and features.  To get Help on any item, RIGHT CLICK on the display item and HOLD the RIGHT button down.  A “Help” feature will appear such as the one shown to the left, providing you with solutions and information.

 

The “Help” feature is also part of the manual as it provides in some instances technical information on how the item works and how it affects the process in the unit. The “Help” feature also provides information on what type of numbers or values should be entered.

 

The “Help” feature will only operate when the unit is Online as the “Help” information comes from the unit itself.

 

 

FAULT INDICATION

 

A faulty display is always indicated and highlighted in RED.  It may have a number in it, but it is preferable to place the mouse cursor over the faulty (RED) display and the FAULT CONDITION will be displayed.  There may be more than one condition, as each display item will have a capability of 15 fault states attached to it.

LetRipp II Windows Tuning Software - Fault Indication

In the above example, a display item “Airt Temp” has a fault, shown by the RED numbers “000”.  By moving your mouse pointer over the display field, a fault message will be displayed “Fault – Input open, short”.

 

 

LOGGING

LetRipp II Windows Tuning Software - Logging

While the LetRipp II Software and the unit are Online, you will be able to Log (Record) a session of running your tune map.  You will only be able to “Play Back”  the logged or recorded data when the LetRipp II Software and the unit are OFFLINE.

LetRipp II Windows Tuning Software - Logging

To Log or Record data, click on the “Logging” item on the Main Menu bar, then select “Start Logging” to commence the logging of the session.  Once the logging has been started, a message will be displayed: indicating the file name that will be used to store the data.  Each time a new recording is done, an incremental counter will be added to the name, so that each file will be unique.  In the above example, the counter is presently at “002”.  The Log File will be stored in the same location as your Tune maps.  By default the location will be C:\Tune_MapFiles. To STOP the recording, either close the program or select “Stop the Logging” under the “Logging” item on the Main Menu.

 

 

DISPLAY UNITS

 

LetRipp II Windows Tuning Software - Display Units Icon

You can change the measurement units and nomenclature of your software by clicking on the icon “Display Units”, as shown to the left.  A dialog box called “Display Units” will appear with the unit selection for pressure, temperature, air fuel ratio, and distance.  Click on the relevant radio button to select your preferred unit of measurement.

LetRipp II Windows Tuning Software - Display Units and Communication Setup

The unit of measurement will be applied to every aspect of the software and entry fields. For example should you change the Air Fuel Ratio from “AFR” to “Lambda” then your entry field will change from 14.7 to 1 for the same reading.

 

Note: It is highly recommended, once a change has been made to the preferred measurement unit, that the LetRipp II Software is restarted.  Should the software not be restarted after a change is made, then the label of an item could be in the incorrect measurement unit and could mislead you into typing an incorrect value.
