Figure 1.1

1. - RPM is the X axis on your table
2. - Fuel Load % is the Y axis on this table, the Y axis will commonly be different depending on table purpose.
3. - These are the Y axis bins
4. - These are the X axis bins
5. - These are the Z axis cells

Changing X & Y "Bin" values and Re-Bin :

There are two ways to change the bin value:

Click on the X or Y header - To Change the bin this way open your table and click on the bin you wish to change, a “ Standard Input “ dialog will open, enter the new value for that bin and click “ OK ” . Now that bin has been changed but no cell values have been modified only change the value of the bin, it will not interpolate the values for the corresponding Z axis cells

Re-Bin Feature - The second way is to click on the button at the intersecting point of your X and Y axis ( See Figure 1.1 A-6 ) . This will open the “ Re-Bin Table” dialog, now make the changes to the X and Y axis bins that you need to suit your engine and click the “Apply New X & Y Values, Interpolate Z“ button at the lower right hand corner of the dialog ( See Figure 1.2 A-3 ) . Now your bin values have been changed and the corresponding cell values or Z axis values have been interpolate, allowing you to fine tune the trouble spots on your table without having to re-tune the whole table. Also keep in mind that if you decide that you do not like that changes made you can use the undo / redo buttons ( See Figure 1.1 A-7 ) on the original table dialog.

The Re-Bin feature allows you to change your X & Y values while keeping the tune as close to the same as possible. All table values are adjusted for newly assigned X & Y values.

Why Re-Bining may be necessary :

All of the ECU firmware for B & G products interpolate the Ve values, this allows you to have fewer X & Y bins unlike ECU's that do not interpolate the values causing a need for larger tables and consequently making tuning of your tables more time consuming and less accurate. As you start to tune your engine you will see that you really only need bins where the engine demonstrates a change from a linear direction. So having said that and also keeping in mind that every engine is different, it is impossible to know what the best value is for each X & Y bin when you start tuning your engine. But as you continue to tune your engine you will then key points along the X or Y Axis that are deviating from the linear direction and require a "Pivot" point to table values. You will be able to adjust your X and Y values to create these pivot points.

You can simply change the X & Y values to what you find more appropriate for your engine byt clicking on them and entering the new values that provide the needed pivot points. However, this will change your current tune in the process as the current Z values are no longer associated with the same X & Y values. This is where the interpolating feature really helps out, as you go through and change your bin values to smooth your map out for your engine the Z value or Cell value is interpolate so that any change made will provide you with a map that is as close to your old map as possible but with the use of the new X and Y values that will allow for a more accurate tune for your engine.

How to Re-Bin :

Figure 1.2

1. These are the X axis bins where you will enter new values and the corasponding Z axis cells will be interpolated.

2. These are the Y axis bins where you will enter new values and the corasponding Z axis cells will be interpolated.

Buttons & Hot Keys :
Button and Hot Key functions are also available on a right click menu.
The " = " key & the button above set the selected cells to the value that is enter in the "User Parameter" dialog.
The " > " key & the button above Increase's the value in the cells that have been selected by the amount specified in the
"Set Increment amount" dialog.
The " > " key & the button above Decrease's the value in the cells that have been selected by the amount specified in the
"Set Increment amount" dialog.
The " - " key & the button above decrease the selected cells to the value entered in the "User Parameter" dialog.
The " + " key & the button above decrease the selected cells to the value entered in the "User Parameter" dialog.
The " * " key & the button above scale the select cells based off of the value entered in the "User Parameter" dialog.
The " / " key & the button above adjusts all of the selected Z axis values to values interpolated between the selected four corners.
The " s " key & the button above smooth out a rough or bumpy table based on the smoothing factor entered in the "Standard Input" dialog.
Right click on the button above to change the smoothing factor. The best way to view the adjustments made by the smoothing feature is in
the 3D Table.
The " f " key will change every value up and to the right of the cell you have selected to the value in the selected cell . So if you select a
cell with a value of 65 every cell up and to the right of that cell will be changed to 65.
The standard copy and paste feature Ctrl + C and Ctrl + V will allow you select the whole table and paste it in another table or even Excel.
History Tail - The history trail is the blue trace line that you see on your table as the engine is running, it trails behind and shows you the
path through the table, that the data from the engine's sensors provided the ECU with to place the marker or history trail in that cell. To
change the number of reads back the history trail will go is set by right clicking on your table and at the bottom of the list you will see
"History Trail Length".Click on "History Trail Length" and it will open a dialog where you eneter the number of reads back you wish to see
on your table.
