Normal Mode Gear Shift Ignition Retard

In normal mode, this is the amount of ignition retard requested by the Shift Ignition Retard module.

It is obtained by plugging the current engine speed into the appropriate Normal Mode Up (or Down) Shift Ignition Retard table. However, its rate of change is limited by Normal Mode Gear Shift Ignition Retard Rate Limiter Down and Normal Mode Gear Shift Rate Limiter Up.
