Fuel Blending And Switching Types - amp e MS3Pro ULTIMATE User Manual

7.7 Table Choices
7.7.0.2 Fuel blending and switching types There are four VE tables, numbered 1 through 4.
Here are some of the possible combinations of fuel table blending and switching. Electrical symbols for switches
and variable resistors illustrate the switch or blend functions.
Method
Single table. One fuel algorithm uses VE1.
This is the most common setup.
Single algorithm, with table-switching. One fuel
algorithm uses VE1 or VE3 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 fuel
algorithm uses a proportion of VE1 or VE3
depending on the blend input and curve (3).
The tables could be blended based on ethanol
percentage in the fuel from a flex-fuel sensor.
Combined tables - secondary additive table.
Fuel is calculated by adding the lookup from VE1
and VE2.
VE2 can be used a tweak to VE1 to add a 4th
dimension to the fuel table e.g. including a throttle
component in a speed-density tune. 0% in the
secondary table means no change, 2% means add
2%
Combined tables - secondary multiplicative
table. Fuel is calculated by multiplying the lookup
from VE1 and VE2.
VE2 can be used a tweak to VE1 to add a 4th
dimension to the fuel table e.g. including a throttle
component in a speed-density tune. 100% in the
secondary table means no change, 102% means
add 2% etc.
