Quick Lambda + Copy Up & Right

As for Quick Lambda except that the new value is copied to the sites
immediately above, right and diagonally above and right if the sites do not
contain a *.

Lambda Was

Adjusts the fuel table value by an appropriate amount by comparing the value
entered by the user to the desired Lambda value in the Lambda Table.

The value that is entered may be either the current Lambda reading from a
lambda meter if tuning online or the Lambda reading from the logged data if
tuning offline.

Note that if a Lambda sensor is directly connected to the ECU then online
tuning may be performed more easily using the Quick Lambda function.

Overall Trim Table

Trims the whole table by the percentage indicated by the Overall Trim then
sets the Overall Trim back to 0.

This is useful during initial tuning of the Fuel Main Table since an existing
table can be used then trimmed to take into account variations in injector
sizing etc. Note that it is better to change the IJPU setup parameter if large
changes are required as this will ensure that the table numbers maintain
sufficient range and resolution, i.e. ensures that the table numbers do not
become too small or too large.

Note that during interpolation the engine may run incorrectly. It is therefore
best if the engine is stopped during the interpolation. If the engine is running,
a warning will be given before the interpolation is started.

Interpolate Vertical Column

Linearly interpolates the current column between the upper most value and
the lower most value leaving the upper most value, the lower most value and
points marked with an * unchanged.

Note that it may be necessary to use the Backspace key to mark the desired
points with an *.

Interpolate Horizontal Row

Linearly interpolates the current row between the left most value and the right
most value leaving the left most value, the right most value and any points
marked with an * unchanged.
