Ignition Sync
The engine's ignition timing must be synchronized with the Infinity Tuner's ignition timing display.
This is crucial with older vehicles that have adjustable distributors, adjustable cam angle sensors,
etc. Most modern engines do not utilize a manual adjustment for ignition timing. However, this
wizard should always be used for verification as sensors can be frequently installed backwards
or upside down. This can catch a problem before damage occurs.
Note: This wizard can only be used when the engine speed is greater than 50 RPM.
Ignition Timing
For synchronizing, the ignition timing can be locked by checking the box.
Allowable values: Min value = 0, Max value = 45
Sync Adjustment
The window includes 4 buttons. Two buttons are used to Advance Timing and TWO buttons
are used to Retard Timing.
