For what it's worth, MAP stands for Manifold Absolute Pressure (sensor) - a
part of the older 'speed-density' engine control system. My 23-year old
LTD
(soon to be donated to a better cause) has one of those. Speed-density
systems calculated mass air flow from manifold pressure, temperature and
engine RPM, instead of measuring it directly by a manifold air flow sensor
(MAF). Perhaps less accurate, but they were never plagued by the caked-on
dust that ultimately makes MAFs read wrong and cause pinging.
