Vehicle Speed Sensor effect on tuning

First, the control module needs powers and grounds. Next, it will not run or will run very poorly without distributor, MAP sensor, throttle position sensor, idle speed control motor, ignition coil, and fuel injectors. Finally, it will run properly in closed loop if it has heated oxygen sensor, engine coolant temperature sensor, and TBI temp sensor. Just about the same applies to full fuel injection, although most, including Magnum engines, use a crankshaft position sensor separate from the distributor, and TBI temp sensor is changed to a intake air temp sensor.
