5.2.4 Linearise


When tuning it is often useful to be able to set two load points with a given value and
approximate the fuel requirements between those two points with a straight line. The linearise
function allows the user set approximate fuel values based on a straight-line approximations
as shown below:


The above map shows the highlighted bar as much higher than the rest. In this case the
estimated fuel requirements for full load operation in this range is 12.288ms, it is unlikely that
the load point to the left of this bar would require such a significant reduction in fuel, it is
more likely that a straight line approximation across the load points would be closer to the
basic fuel requirements. In this case a straight-line approximation will be applied between the
2 extreme bars as follows:


All the bars between the 2 extreme bars are highlighted:
