• Y axis can be selected in "Table axis setup"

Idle ignition can drop back to main map with manifold pressure. See "Idle ignition

setup" menu. Idle ignition timing can have modifiers under "M2,Ignition trims".

Idle speed table

Idle speed control.

Sets engine idle speed based on battery voltage.

Example:-

Required idle speed 800 RPM

Battery voltage(Volts)

12.00 13.50

RPM 1000 800

The engine would idle at 800 RPM when battery voltage is 13.5 volts or higher.

If battery voltage drops to 12.0 volts the idle speed will increase to 1000 RPM.

Idle ignition setup

Idle table select

Select idle ignition timing table.

Options:

Disable: Does not use the idle ignition table.

Idle ignition table

Uses the idle ignition table.

Idle ign delta RPM X axis of idle ignition tables is the error in idle speed..

Idle ign threshold

The manifold pressure that changes back to the main ignition table.

Typical=65.0

This only applies if "Idle table select" is set to the idle ignition table.
