This will leave the selected bar highlighted and will cause the next bar to the left or right to
become highlighted.
The up and down cursor key result in a relatively small change in height of the bar or bars
selected. To facilitate quick tuning there are 4 key combinations that allow different
increments in bar height.
The key combinations and bar increments:
Key Combination Increment
↑

0.016ms
PgUp or PgDn 0.128ms
Shift-PgUp or Shift-PgDn 0.5120ms
Ctrl-PgUp or Ctrl-PgUp 1.0240ms
5.2.2 All Ranges
When tuning 3-dimensional maps it can often be useful to make changes to the same bar in all
the ranges of the map. This allows the user to tune basic fuel values across load in one engine
speed range for all the ranges so the fuel will be at least close to the requirements across the
full range. “All Ranges” is enabled and disabled by pressing:
ALT-R
When the software is in any of the ranges of a 3-dimensional map. The text “All Ranges” will
appear in the middle left of the screen and will remain there until the All Ranges function is
disabled. When All Ranges is enabled all changes made in any range of a three dimensional
map will affect the corresponding bar in all the other ranges of that map.
5.2.3 Percentage Changes
When tuning it can be useful to apply a percentage change to all or part of the maps. An
example of this would be when the injectors are changed for units with a higher or lower flow
rate. To make a percentage change select the bars that need to be changed and press:
ALT-P
The software will then prompt the user to type a percentage change, if a positive number is
typed then a percentage increase will result, if a negative number (any number with a ‘-‘
prefix) is typed a percentage decrease will result.
NOTE:
The percentage increase and decrease calculations are based on the current
height of the selected bars. This means that if a bar has a 50% increase applied
and the user wishes to reverse this increase, a decrease of 33% is required. For
example: if a bar had a height of 4ms and it has a 50% increase applied:
4ms x 50% = 2ms
The new height of the bar will be 6ms.
To reduce the bar to 4ms again by using the percentage change function 33%
must be used since.
6ms x -33% = 4ms
