65. Learning
The primary function of the Learning feature is to minimize the amount of O2 correction
required to achieve the user defined values in the air/fuel ratio table. If learning is enabled, the
ECU monitors the % O2 correction. If the % O2 of correction is equal to or greater than 5%, the
ECU begins to Learn. Once it begins to learn, the ECU corrects the corresponding base fuel
pulse width (BLM up to +/- 25%) until it is within +/- 5% of the value in air/fuel ratio table. The
Learning function is only applicable to fuel correction, not Spark. The ECU does not allow the
Learning function to be enabled at idle or Wide Open Throttle (.3 to .9 Bar).
66. Configure (Learn Parameters)

The following screen will open.
Keep the left mouse button depressed and slide the mouse cursor down until Configure is
highlighted. Release the mouse button and the drop down screen below will open allowing the
user to Configure the Learning feature.
