subtract to influence idle speed. Some engines may like more, some may like less. 5 degrees is
usually a good starting point.
The final ignition timing the engine sees (Total Timing) is composed of three components:
Base Timing
Value from RPM‐based timing curve
+ Idle Adv
Timing added or subtracted to influence idle speed (Optional. See Advanced menu.)
+ Vacuum Adv
Timing added based on manifold vacuum (Optional. See Advanced menu.)
= Total Timing
Timing‐related data is only valid when EZ‐EFI® is controlling timing.
Live Data
The Live Data section of the hand-held consists of a series of dashes that display live ECU data.
To switch between dashes or to return to the home screen, use the tabs at the bottom of the screen. The
text will highlight green to indicate the current screen.
Across the top of every dash are 4 LEDs that indicate the following:

Learning
This indicates that all of the enable conditions for
learning are met and that learning is currently enabled.
This can be used as feedback to give the driver a feel for
when the ECU will or will not learn.
Gray
Green
O2 On
The oxygen sensor has been initialized and is providing
feedback to the ECU. This must be ON before closed
loop fuel control is possible.
Gray
