7.7.0.6 Boost table switching Like with the AFR tables, there are two boost tables, and you can either use
one table, switch tables, or blend them. These work the same way as AFR table switching, except that you have
the option of setting the boost table switching to use a gear input instead of a hardware switch, so you can use a
different boost map in lower gears if you are traction limited. The boost table blending uses blend curve 6.
Note that you could effectively create a third boost setting by using a switch to shut off power to a boost control
solenoid. The result would give you the lowest boost level permitted by the wastegate spring.
In Closed Loop mode these two tables are target boost. In Open Loop they are raw boost solenoid duty cycle.
Method Diagram
Single table. Boost is determined from boost table
1.
This is the most common setup.
Switched tables. Boost is determined from boost
table 1 or boost table 2.
Either a physical switch or a gear option
determines which table is used.
Blended tables. Boost is determined as a blend
between boost table 1 and boost table 2 using
Blend Curve (6).
7.7.1 Table Switch / Dual Fuel
This screen sets up many of the table switching options, as well as settings for running an engine on multiple
fuel types. You can switch a wide variety of tables, not just VE and spark. Since fuels have different rates
of evaporation and different amounts of sticking to walls, you can also change cranking settings, warmup and
afterstart enrichment, and acceleration enrichment as well.
