Secondary algorithm blended table. Fuel is
calculated from VE1 using the primary fuel
algorithm and also from VE2 using the secondary
fuel algorithm and then the result is blended.
This could be used to have a blend between a
Speed-Density in VE1 and MAF tune in VE2. The
blend curve (1) allows you to alter where each
algorithm is in use. Each table should be tuned
individually i.e. set the curve to 0% and tune VE1,
then set to 100% and tune VE2, afterwards enable
blending.
Two way blend.Fuel is calculated from VE1 and
VE3 using the primary fuel algorithm. These are
blended. Then VE2 and VE4 are calculated using
the secondary fuel algorithm and blended. The
VE1/3 result is then blended with the VE2/4 result.
This could be considered for E85 (VE3/4) vs
regular gasoline (VE1/2) where algorithm blending
is also used between left and right, such as a
blend of Speed Density and MAF.
This is incompatible with ’Dual Table’ as that uses
VE3/4 for the second bank.
Two way blending is complex ! Do not enable it
without fully tuning each individual table.
Dual table. Fuel for injector bank 1 is calculated
from VE1 and fuel for injector bank 2 is calculated
from VE3.
This could be used where an engine has radically
different fuel requirements between banks (or
cylinders in a V twin.) or as part of a dual-fuel
install where the second bank is used for LPG or
methanol etc.
Injector staging. Fuel is calculated from VE1 and
the staging parameters determine the split
between primary and secondary injectors.
This is typically used on engines with a large
dynamic range so that small injectors may be used
at low loads for good tunability with additional
(staged) large injectors coming online at full power.
This concept is used from the factory on Mazda
rotary engines.
More variations. There are many more
combinations possible to include double blending,
switching between blended tables etc.
These are partially set in the Basic / Load Settings and partially set in the Table Choices menu.
