A speed limiter is a governor that is designed to keep you from accelerating past
a designated speed. This is achieved by programming the EEC to cut off spark
and fuel to the engine after reaching the pre-programmed speed. There were
never any speed limiter placed on any year SC or XR7 with the manual
transmission. Some of the 89-93 SCís and XR7ís with the AOD were speed
limited at or just under 130 mph, but not all have this limiter. All 94-95 SCís
with the 4R70W were supposed to be speed limited at 125mph.
