Found under 'Edit-Table' drop down menu.

The Decel Table adjusts deceleration enleanment. This table allows the removal of a small amount of fuel during a decrease in throttle position or during a decrease in manifold pressure. The table is "Enleanment Multiplier" vs Temperature.

Increasing a cell value will increase the fuel enleanment to the engine, increasing the fuel removed.
Decreasing a cell value will decrease the fuel enleanment to the engine, decreasing the fuel removed.

This fuel gets subtracted from the base pulse width calculation. Make sure to check this table during tuning if decell popping is occurring. A colder engine condition requires a larger Enleanment Multiplier. Double click on a cell and use the up and down arrow to adjust.
