7.7 Table Choices 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL
Dual table
Fuel for injector bank 1 is calculated from VE1 and fuel for injector bank 2 is calculated from VE3. This can
also be used in conjunction with VE1/2 (and VE3/4) combined tables and algorithm blending. It is not compatible
with table switching or blending from VE1 to VE3.
7.7.0.4 Spark / ignition blending and switching types There are also four spark tables, with switching and
blending options similar to fuel.
Some options are not present as they do not apply to ignition; you cannot multiply spark tables, for instance, or
stage two sets of spark plugs (although the rotary split tables are a similar idea).
Method Diagram
Single table. One ignition algorithm uses Spk1.
This is the most common setup.
Single algorithm with table-switching. One
ignition algorithm uses Spk1 or Spk3 depending on
table switch setting/input.
Could be used with dual-fuel or also as a method
to extend effective table size.
Single algorithm with table-blending. One
ignition algorithm uses a proportion of Spk1 or
Spk3 depending on the blend input and curve (2).
The tables could be blended based on ethanol
percentage in the fuel from a flex-fuel sensor.
